ii
Environmental Consciousness
NCR is demonstrating its concern for the environment by designing an
intelligent power management system into this terminal that operates
efficiently whether the system is in a stand-alone or network
environment.
Grounding Instructions
In the event of a malfunction or breakdown, grounding provides a
path of least resistance for electric current to reduce the risk of electric
shock. This product is equipped with an electric cord having an
equipment-grounding conductor and a grounding plug. The plug must
be plugged into a matching outlet that is properly installed and
grounded in accordance with all local codes and ordinances. Do not
modify the plug provided – if it will not fit the outlet, have the proper
outlet installed by a qualified electrician. Improper connection of the
equipment-grounding conductor can result in a risk of electric shock.
The conductor with insulation having an outer surface that is green
with or without yellow stripes is the equipment-grounding conductor.
If repair or replacement of the electric cord or plug is necessary, do not
connect the equipment-grounding conductor to a live terminal. Check
with a qualified electrician or service personnel if the grounding
instructions are not completely understood, or if you are in doubt as to
whether the product is properly grounded.
Use only 3-wire extension cords that have 3-prong grounding plugs
and 3-pole receptacles that accept the product’s plug. Repair or replace
damaged or worn cords immediately.

Chapter 2: Installing the Hardware Infrastructure
Chapter Overview
This chapter describes how to install the RealPrice hardware
infrastructure. This includes the following components:
• CBSs
Note: The RealPrice Release 3.4 Communication Base Station (CBS) is
a 10/100Base-T Ethernet device and may be used in a 10 Base-T or
100Base-T Ethernet network. CBS power supplies
• Data and power cables
• Transmit and receive antennas
For information about ordering these parts, refer to Appendix A.
Note: After the RealPrice hardware is installed, the RealPrice software
must be configured and the site must be RF certified. Refer to the
following documents:
• "Chapter 4: CBS Configuration" in the RealPrice Software Guide
(B005-0000-1479)
• RealPrice RF Certification Utility Guide (AIP-000269) or the "Certify
RF Infrastructure" section of the RealPrice Implementation Guide
(B005-0000-1250).
2-2 Chapter 2: Installing the Hardware Infrastructure
Policy for New Installations
It is the CBS installer's responsibility to ensure that CBS firmware
revision levels are correct at the time of installation.
The correct firmware level is one of the following:
1. The latest firmware version available at www.ncr.com -> Support -
> Drivers and Patches -> Retail Support Files -> Retail RealPrice
Support Files.
2. A customer-specified firmware version. A small number of
customers do not allow installation of any new firmware that has
not been integration tested in their lab. The installation project
planner (usually NCR Professional Services) informs if this is the
case.
Due to supply chain logistics, new CBSs may not come pre-installed
with the latest firmware. Always verify.
To keep up to date, subscribe to the RealPrice software/firmware
update mailing list. NCR uses this list to announce new firmware
releases. Subscribe by sending an email to majordomo@lists.ncr.com
with "subscribe realpriceupdates" in the body of the message.
Installation Recommendations
• The most efficient way to install the RealPrice hardware
infrastructure is in one pass through the store. Install the CBSs,
antennas, power cables, and data cables all at the same time.
• Whenever possible the CBSs should installed at 15 feet or lower so
that serviceability by the ladder is possible.
• The primary CBS must be installed so that it is serviceable from the
floor.
• Label all CBSs, antennas, and data cables. Document how
components are labeled for future reference.
• Label all power supplies and 48V cables for serviceability.
Chapter 2: Installing the Hardware Infrastructure 2-3
• Power supply labels should indicate which CBSs they power,
and the fact that they are part of the RealPrice ESL system.
• The 48V cable labels should indicate which CBS they lead to.
• Neatness makes servicing the system much easier.
• Do not mount the power supply AC main power strips on the floor
or in a place where they might be accidentally switched off.
• Do not mount power supplies on the floor or in a place where wires
might get accidentally pulled out.
• Provide slack in cables, especially in receive antenna cables.
• Test the system as it is being installed. Refer to “Chapter 3, CBS
Network Utilities and Diagnostic Tools” in the NCR Utilities Guide
(B005-0000-1487) for information on testing.
• Provide AC power that meets NCR requirements for the power
supplies. Refer to the "Power, Grounding and Distribution
Requirements" section of the RealPrice Site Preparation Guide (B005-
0000-1501).
• Test wiring as it is installed. Some installation problems are
extremely difficult to diagnose later.
• RealPrice Release 3.x requires the RF infrastructure to be connected
to the site's RealPrice Software Controller to test the infrastructure.
Refer to the following for information on testing the infrastructure
and site certification:
• RealPrice Implementation Guide (B005-0000-1250)
• RealPrice RF Certification Utility Guide (AIP-000269)
• RealPrice III Certification Site Survey Policy (497-0421218)
2-4 Chapter 2: Installing the Hardware Infrastructure
General Layout Instructions
• The cable length between any two devices (10/100Base-T
compatible Ethernet hub to CBS or CBS to CBS) cannot exceed 100
m (328 ft.).
• The maximum number of Ethernet levels beyond the primary CBS
is three (3).
• The maximum total cable length is as follows:
Cable Maximum Cable Length
Ethernet (primary CBS to last CBS in chain) 300 m (984 ft.)
Power supply to last CBS in the chain 162 m (532 ft.)
• Use only NCR authorized communication cable.
• Communication cables must be secure and locked into their
connectors.
• The maximum number of CBSs per store is 85.
• If the communication cable is routed through an exposed area, such
as up the side of a wall, across the top of a freezer where
merchandised is stacked, or in an elevator shaft, it must be in a
conduit and the conduit must be connected to the building ground.
• The minimum distance between a communication cable and a
fluorescent, neon, or incandescent light is 30 cm (12 in.).
• Minimum distance between a transmit or receive antenna and a
neon light is 2.43 m (8 ft.).
• All communication cable connections must be protected from
electrical and mechanical deterioration. The deterioration of
communication cable connections due to corrosion or electrolysis,
especially in a humid or corrosive atmosphere, may result in
electrical noise.
Chapter 2: Installing the Hardware Infrastructure 2-5
• Minimum distance between the transmit antenna and any receive
antenna connected to 1 Watt or 500 mW CBS's is 9.2 m (30 ft.).
Minimum distance between the transmit antenna and any receive
antenna on a 100 mW CBS is 6.2 m (20 ft.). There is no minimum
distance between two transmit antennas.
• The minimum distances between a communication cable and
electrical equipment/associated power cables are as follows:
Maximum Rated Circuit Power Unshielded Power Cables Shielded Power Cables
1 kVA 30.5 cm (14 in.) 2.54 cm (1 in.)
2 kVA 45.7 cm (18 in.) 5.08 cm (2 in.)
5 kVA 60.9 cm (24 in.) 15.24 cm (6 in.)
Over 5 kVA 152.4 cm (60 in.) 30.48 cm (12 in.)
• All interconnecting wiring between the Ethernet hub, CBSs, and
power supplies is low voltage wiring. This wiring must conform to
all local and national electrical codes for the routing of commercial
signal wire.
• Do not route communication cables outside the building.
2-6 Chapter 2: Installing the Hardware Infrastructure
Tools and Supplies
RealPrice infrastructure installers must have access to the tools
typically found in an electrician's tool box. Additional tools and
supplies an installation team may require are shown in the following
table.
Tool/Supply Quantity
Cable ties 10 per CBS
RJ45 Modular Jacks 2 per cable plus spares
RJ45 crimp kit 1
Low-torque electric screw driver 1
ESL removal tool 1 per installer

Chapter 2: Installing the Hardware Infrastructure 2-7
CBS Installation
The following sections describe the preparation, cabling, and
installation of the CBS and its related components.
CBS Ethernet Cable Connections
The RealPrice CBS uses a star topology and has an integrated Ethernet
switch that can connect to three other CBSs. RealPrice supports up to
three (3) levels below the primary CBS. This topology results in the 85
CBS maximum mentioned in the “General Layout Instructions”
section. The following illustration shows an example 85 CBS
configuration, its Ethernet cable connections, and the maximum
number of CBSs on each level.

CBS Numbering
CBS’s are identified in the CBS Manager section of the RealPrice CBS
configuration file (DNCBSCONFIG.XML) with a unique number and a
host name or IP address. Using the numbering scheme shown in the
illustration helps identify the level in which the CBS is connected in the
topology when running diagnostic tests and analyzing diagnostic logs.
This scheme is as follows:
• Primary CBS = always 1
• Level 1 = CBS 11-14
• Level 2 = CBS 111-144
• Level 3 = CBS 1111-1444
CBS configuration details are described in “Chapter 4: CBS
Configuration” in the RealPrice Software Guide (B005-0000-1479).
Chapter 2: Installing the Hardware Infrastructure 2-9
CBS Power Supply Cable Connections
The CBS Power Supply can support up to five (5) CBSs. The following

CBS Timeslots
Each CBS uses two (2) of the 24 available Timeslots to communicate
with the ESLs in its coverage area. Timeslots are assigned in pairs (1,
13; 2, 14; 3, 15; and so forth) to each CBS.
To provide the most efficient communication network, adjacent CBSs
must have timeslots that differ. The optimal difference is 6, but in larger
installations, this may be difficult to accomplish.
The timeslots for the CBSs shown in the Sample Store Cabling
illustration in the previous section could be set as follows to achieve
efficient communications:

CBS timeslot configuration can be done using the CBS Setup options in
the RealPrice Support Utility (dnutils.exe) after the RealPrice Base
Software is installed and the RealPrice CBS Configuration file is
modified. Refer to “Chapter 2: The RealPrice Support Utility” in the
RealPrice Utilities Guide (B005-0000-1487) for details on how to use this
utility to view and set CBS timeslots for Windows installations. Refer
to the "dncbssetup (CBS Setup Utility)" section of “Chapter 7: Testing
and Troubleshooting in AIX” in the RealPrice Installation and Service
Guide (B005-0000-1247) for details on how to use this utility to view and
set CBS timeslots for AIX UNIX installations.
CBS Hopping Table
Each CBS is assigned a set of hopping frequencies in the 2.4 gHz range
that it uses to communicate with the ESLs. There are 565 frequencies
available numbered 0-564. CBS models have 83 frequencies in their
hopping table associated with a Hopping Table Index (0-82) in a single
frequency band. Local regulation may limit the number of frequencies
permitted. For example, in France, only 142 frequencies are used.
To provide the most efficient communication network, CBSs must not
have the same hopping table.
Chapter 2: Installing the Hardware Infrastructure 2-13
Hopping frequencies are assigned during the manufacturing process,
but can be modified using the RealPrice Support Utility. Refer to
“Chapter 2: The RealPrice Support Utility” in the RealPrice Utilities
Guide (B005-0000-1487) for details on how to use this utility to view and
set the CBS Hopping Table after the RealPrice Base Software for
Windows NT/2000/XP is installed. Refer to the "dncbssetup (CBS

The CBS product label identifies the model number, serial number, and
unique MAC address of the CBS. The least significant 6 hexadecimal
characters of the MAC address are used to specify the host name for
each CBS in the CBS Manager section of the RealPrice CBS
Configuration file (DNCBSCONFIG.XML). The host name format is
NCRDNETXXXXXX where XXXXXX represents the 6 characters from
the MAC address (357942 for the sample label above).
When you complete the RF infrastructure installation, you need to
assign IP addresses and verify CBS communications. The
recommended method for managing IP addresses is through the use of
Static IP Addressing. A DHCP Manager from a DHCP Server may also
be used. Refer to “Chapter 4: CBS Configuration” in the RealPrice
Software Guide (B005-0000-1479) for details about assigning CBS
addresses in your Ethernet network and also how to enter the CBS
configuration information in the CBS Configuration File. Refer to the
"Verify Communication Links" section for how to verify CBS
communications.

Connecting Ethernet Data Cables
From the primary CBS, a data cable connects every secondary CBS in
the system as shown previously in “CBS Ethernet Cable Connections”
section. Note that the Uplink data connector is used to connect to a
higher level CBS and the data connectors 1, 2, 3, and 4 are used to
connect to lower level CBSs. Otherwise, use standard CAT5 Ethernet
wiring conventions.
General Comments Regarding Ethernet Wiring
In this section, the assumption is that RJ45 connectors are being
crimped directly to the ends of each cable. It is acceptable to use punch-
down jacks and pre-fabricated CAT5 patch cables, or any other
generally accepted CAT5 wiring methodology.
Chapter 2: Installing the Hardware Infrastructure 2-23
Connecting the Ethernet Hub to the Primary CBS
Each store configuration has only one primary CBS. All other CBSs are
secondary CBSs. The primary CBS is connected directly to the Ethernet
Hub. Standard 4 pair, CAT5, 24 AWG solid, unshielded cables are
required for all Ethernet communications.
Locate the Ethernet hub.
1. Cut a length of data cable that is long enough to reach from the hub
to the primary CBS. Refer to "General Layout Instructions" section
for maximum cable length information.
2. On each end of the data cable, install the wires into an RJ45
connector as shown in the following illustration and then crimp the
connector onto the cable.

3. Plug the data cable into the Uplink data connector on the primary
CBS.
Connecting Secondary CBSs
Follow these steps to connect the secondary CBSs:
1. Cut a length of data cable that is long enough to reach from one
CBS to the next CBS.
2. On each end of the data cable, install the wires into an RJ45
connector as shown in the previous illustration and then crimp the
connector onto the cable.
3. Plug the RJ45 connector into data connector 1, 2, 3, or 4 and into the
Uplink data connector of the next CBS.
4. Repeat steps 1 – 3 until all secondary CBSs are linked by a data
cable.
Connecting Power Supply Cables
Refer to the illustrations in the “CBS Power Supply Cable Connections”
section. Power supply cable routing is store dependent. The power
connector provides flexibility to connect additional CBSs in series from
one CBS to another or in parallel from a CBS to four other CBSs.
Connecting CBS Power Supplies to AC Power
Place the CBS power supplies with the host computer system, if
possible. Plug all power supplies into a common power strip so that
they can be powered on and off at the same time for reset purposes.
AC main power strips must have an indicator light to prevent
confusion about whether the system is currently powered on or off.
DO NOT remove power by unplugging the +48 VDC plug from the
power supply or the CBS as this may cause damage to the CBS.
Chapter 2: Installing the Hardware Infrastructure 2-25
Cable length restrictions may prevent installing all power supplies in
the same location. In this case, it may be necessary to install a
separately switched AC main circuit so that the power supplies can
still be controlled at the same time. If local electrical codes or special
circumstances require the installation of more than one switched AC
main circuit for the power supplies, all the main circuit switches
should be in the same easily accessible location.
Do not install the CBS power supply in the ceiling.
1. Have an electrician install new AC receptacles if needed.
2. Do not plug the CBS power supply into an AC receptacle until
steps 1 – 6 in the next section are complete and the transmit
antenna is connected to the CBS.
Connecting CBS Power Supplies to CBSs
Each CBS power supply can power up to five CBSs as shown
previously in the store configuration illustration. The wiring is the
same for each group of up to five CBSs.
Follow these steps to connect a CBS power supply to each group of up
to three CBSs:
1. Cut a length of power cable that is long enough to reach from the
power supply to a CBS.
2. Splice the power cable wires to the pigtail supplied with the power
supply (black to black and red to white) and then crimp the
provided crimp connectors over the splices.

5. Install the power cable wires into the connector (white into pin 1, 3,
5, 7 or 9 [48 V] and black into pin 2, 4, 6, 8 or 10 [Ground]). Use
pins in pairs: 1-2, 3-4, 5-6, 7-8, and 9-10 for each power cable
connection at the CBS.
6. Plug the connector back into the CBS.
7. Insert the AC power cable into the power supply's AC receptacle.
8. Connect the AC plug to the AC power source.
9. Turn on AC power by setting switch to ON position. (Green light
indicates that power source is working properly).
Caution: To prevent damage to the transmitter, the transmit antenna
must be connected to the CBS before applying power to the CBS.
Chapter 2: Installing the Hardware Infrastructure 2-27
CBS Antennas
Two types of antennas are available:
• Transmit
• Receive
The transmit and receive antennas look similar, but have the following
differences:
• The transmit antenna has a small blue dot on the antenna case.
• The transmit antenna has a 1.83 m (6 ft.) cable attached. The cable
has a threaded reverse polarity TNC connector that attaches to the
CBS.
• The receive antenna has a 0.25 m (10 in.) cable attached. The cable
has a female BNC connector. A CBS Receive Antenna cable (1424-
C057-0180) is used between the attached cable and the CBS. This
cable has two BNC connectors.
14086
Note: The new Antenna cable for Freezers is 6 meters (19 feet) long.
Note: With 100 mW CBSs, a 15 m (49 ft.) receive antenna cable
1416-C520-0150 must be used instead of the usual 18 m (59 ft.) receive
antenna cable.
Consider the following when installing antennas:
• Install the antennas at the same time that the CBSs are installed.
• When connecting cables to antennas (especially Transmit
antennas), make sure connections on both ends are properly
aligned on the threads and are screwed down completely.
• Use care when connecting cables so the antenna cable connector is
not loosened from the circuit board inside the antenna.
2-28 Chapter 2: Installing the Hardware Infrastructure
• On a suspended ceiling, mount the antennas to the ceiling tile. In an
open ceiling, hang the antennas from the roof trusses.
• When mounting the antenna, face the front of the antenna (the side
opposite the cable connector) towards the ESLs, with as few
obstructions between it and the ESLs as possible.
Caution: The transmit antenna is required to comply with FCC RF
exposure requirements for mobile transmitting devices. A separation of
20 cm (8 inches) or more must be maintained between the antenna and
all persons during device operation to satisfy RF exposure compliance.
Installing CBS Antennas
The transmit antenna and receive antenna kits include the same
mounting hardware. The installation procedures for the transmit and
receive antennas are the same.
Note: Observe the following precautions to avoid RX antenna ESD
failures:
1. Always connect the RX cable to the CBS before connecting the cable
to an RX antenna.
2. Keep antennas in their anti-static packing bags until they are ready
to be installed.

Mounting an Antenna in a Freezer
20355
Freezer Bracket
Freezer Gasket
7730 RealPrice CBS freezer layout guidelines sometimes require
mounting receive (RX) antennas inside of freezers. To prevent
mechanical and moisture damage to the antenna or freezer, use the
following installation guidelines:
• Seal all cable entry holes with permagum sealing compound. Do
not use expanding foam.
2-32 Chapter 2: Installing the Hardware Infrastructure
• If the customer stacks merchandise on top of the freezers, protect
exposed RX antenna cables with metal conduit.
• Protect the RX antenna BNC cable connector from the freezer
environment.
Note: Maintain a minimum distance of 9.2 m (30 ft.) between each 1 W
or 500 mW CBS's transmit and any receive antennas. Minimum
distance for a 100 mW CBS's transmit and receive antennas is 6.1 m (20
ft.).
To install an antenna in a freezer:
1. At the desired location, drill one (1) 16 mm (5/8 in.) hole for the
antenna cable.
2. Route the antenna cable through the hole in the Freezer Gasket.
3. Place the Freezer Bracket over the Antenna and check the
alignment of the assembled parts as follows.
Note: The round and elongated mounting holes in the gasket and
bracket are matched together.
• The antenna alignment guides are centered between the edges of
the elongated hole in the gasket.
• The gasket does not extend past the edge of bracket on any side.
Note: Proper alignment of gasket, antenna, and bracket is necessary to
make a secure seal against the ceiling.
4. Route the antenna cable through the hole in the ceiling.
5. Raise the assembled parts up against the ceiling.
6. Using the Freezer Bracket as a template, drill two (2) 3 mm (0.125
in.) holes in the freezer ceiling for the mounting screws.
7. Use the two (2) self-tapping screws to secure the bracket to the
ceiling.
Chapter 2: Installing the Hardware Infrastructure 2-33
8. Connect the end of the Receive antenna cable to the CBS, then
attach the Receive antenna pigtail to a Receive Antenna Cable.
Connect the other end of the Receive antenna cable to the CBS.
Note: Protect the RX antenna BNC cable connector from the freezer
environment.
• Water condensation inside and dripping water from outside an
unprotected BNC connector will trigger electrolytic corrosion
that will eventually destroy the connector.
• Carefully choose freezer RX antenna locations so that the inline
BNC cable connectors are in a room temperature environment
outside the freezer wall.
• For conventional stand-alone freezers, use the 7730-K050-V003
"Kit - Rx Antenna w/18m cable" or 7730-K054-V003 "Kit - Rx
Antenna w/15m Cable (for 100mW CBS)." These antennas
have a 25cm (10inch) antenna lead.
• For large walk-in and oversized freezers with high ceilings, use
the new long-lead 7730-K055-V002 "Kit - Rx antenna (6m lead)
and 12m cable." These antennas have an extended 6m (20ft)
antenna lead for better freezer routing, but they must be used
with the corresponding shortened 12m (39ft) antenna cable for
proper operation.
• In special situations, it is possible to seal the inline BNC
connector from the freezer environment. See the detailed
instructions below.
9. Use cable ties to secure the antenna cable.
10. Seal all cable entry holes with permagum sealing compound.
• Unsealed holes will cause icicles around entry holes and frost
buildup on nearby product. If the inline BNC connector is not
protected, condensation will drip down the antenna cable and
trigger electrolytic corrosion inside the connector that will
quickly destroy it.
2-34 Chapter 2: Installing the Hardware Infrastructure
• To use permagum, roll a walnut-sized piece into a rope shape
and push as much as possible into both ends of the cable entry
hole. Permagum-type sealing compound looks like modeling
clay and is commonly available from HVAC and electrical
supply houses. One example is Virginia KMP brand sealing
gum, catalog number PP-22V, from www.virginiakmp.com.
• If replacing an antenna or cable, re-seal the cable entry hole.
New permagum is best, but existing permagum can be re-used,
if necessary.
• DO NOT use any type of expanding foam sealant, for example
Dow brand "GREAT STUFF" polyurethane foam or DAP brand
DAPtex latex foam. NCR has found that these materials do not
cure properly at freezer temperatures or in the presence of
water condensation.
Note: If the customer stacks merchandise on top of the freezers,
protect exposed RX antenna cables with metal conduit. Customers
sometimes showcase large items on top of freezer units. These items
will damage exposed RX antenna cables. Protect cables with short
lengths of metal or plastic electrical conduit. Use appropriate straps to
keep the conduit in place.
Special Instructions for Sealing Inline BNC Antenna Connectors That
Must Be Located Inside Freezers
This BNC sealing procedure is only recommended for the following
situations:
• If servicing a walk-in or oversized freezer that was installed before
the previous guidelines were available
• If installing RealPrice infrastructure at a new site and long-lead RX
antenna kit 7730-K055-V002 cannot be obtained in time to meet the
installation schedule
Chapter 2: Installing the Hardware Infrastructure 2-35
Materials Required:
• 12in (30.5cm) length of CoaxSeal™ #105 hand-moldable plastic
material (http://www.coax-seal.com). This material is available
from Radio Shack and commercial electrical supply houses.
• 12in (30.5cm) length of black electrical tape, 3M Super 88 Scotch®
Brand Vinyl Electrical Tape or equivalent
Procedure:
1. Connect the RX antenna to the RX cable inside the freezer.
2. Wrap the in-line connectors with electrical tape. The electrical tape
allows the Coax-Seal™ material to come off cleanly in case of future
servicing.
3. Wrap the connection with a 12in (30.5cm) length of Coax-Seal™
material. Wrap beyond the ends of the electrical tape in order to
ensure a watertight seal.
4. Shape and form the Coax-Seal™ material to ensure a good seal.
Note: Keep the electrical tape and Coax-Seal™ material warm inside a
jacket as much as possible while working in the freezer. This keeps
them flexible for better adhesion.
Note: To prevent condensation from becoming trapped inside the
cable connection, do not remove antennas or cables from the freezer
once they have become cold. If they are removed, then keep them
outside the freezer until all signs of condensation have evaporated
before bringing them back in.
2-36 Chapter 2: Installing the Hardware Infrastructure
Hanging an Antenna from a Roof Truss
Note: Maintain a minimum distance of 9.2 m (30 ft.) between a 1 W or
500 mW CBS's transmit and receive antennas. Minimum distance for a
100 mW CBS's transmit and receive antennas is 6.1 m (20 ft.).
To hang an antenna from a roof truss (or other object) refer to the
illustration on the following page and these instructions:
1. Screw the 0.61 m (2 ft.) threaded rod into the 1/4-20 UNC hole in
the back of the antenna.
Note: A 2 ft. threaded rod is supplied in the antenna kit. If the open
ceiling installation requires a longer section of threaded rod, it is
expected the requirement be pre-determined and the longer rod be
supplied by the installer.
2. Secure the antenna cable to the threaded rod using three equally
spaced cable ties.
Note: Attach the 0.25 m (10 in.) Receive antenna pigtail to a Receive
Antenna Cable before securing the cable to the threaded rod as shown
in the illustration.
3. In the desired location, hold the antenna cable against a roof truss
and lower the antenna to the desired height.
4. Use a cable tie to hang the antenna cable from the roof truss.
Caution: Antenna cables must be secured to a roof truss as shown in
the following illustration. Do not hang the antenna from a CBS's
connector as the connector cannot withstand the weight of the
threaded rod, cable, and antenna.
5. Connect the antenna cable to the CBS.
Note: Always connect the RX cable to the CBS before connecting the
cable to an RX antenna.
6. Use cable ties to secure the antenna cable.

CBS Hardware Configuration
After all RF infrastructure components have been installed, and the
Ethernet cabling and power supply cabling has been circuit tested for
continuity, the system can be powered-up to establish the connection
between an Ethernet network and the RealPrice CBS units. IP allocation
can be configured using Static IP Addressing or using a DHCP Server.
Static IP addressing may be required for the following situations.
• For permanent assignment when you are not able to use the
existing DHCP Server/DHCP Manager in your communication
network
• For permanent assignment when you do not have a DHCP
Server/DHCP Manager in your communication network and
customer does not wish to have one
• For temporary assignment of IP addresses to test the RF
infrastructure
The decision is made during site survey interviews between the PS
Project Manager and the customer. The IP addresses, subnet mask, and
gateway address are provided by the customer’s IT support group.
Refer to the “Chapter 4: CBS Configuration” in the RealPrice Software
Guide (B005-0000-1479) for details about how to configure the IP
addresses for the RealPrice CBS units.
Verify Communication Links
Use the following procedures to verify your communication links.
1. Power-up each CBS.
2. Verify that each CBS link status LED is lit.
3. Use the Ping utility to ping each CBS using its IP Address to verify
connectivity.
Chapter 2: Installing the Hardware Infrastructure 2-39
Note: If your network is using a Dynamic IP Addressing, use the ARP
utility to display a list of the dynamically assigned IP Addresses. Refer
to “Chapter 4: Common Diagnostic Utilities” in the RealPrice Utilities
Guide (B005-0000-1487) for details on ARP. Cross reference the CBS
MAC address to the CBS number assigned in the store layout to
confirm all CBSs respond to the ping test. If reserved IP addresses were
used, refer to that list to confirm all CBSs respond to the ping test.
Document CBS Network Addressing
Note the CBS Numbers, MAC Addresses, and CBS IP Addresses on the
store layout for reference purposes.

Firmware Downgradability
Once a CBS is installed with firmware 3.2.0 or higher, it cannot be
downgraded below firmware 3.2.0 except by returning it to the factory
or by contacting NCR Level 4 support for special assistance. This is
true regardless of the CBS hardware release. The ftpdl.exe utility
reports an error and the CBS remains unaffected if downgrade is
attempted. Note that firmware 3.2.0 does not support the TFTP
bootloader feature.
3-16 Chapter 3: Maintenance
Unlike the firmware 3.2.0, 3.4.0 CBS cannot be downgraded as low as
the CBS hardware can allow in the previous chart. For example, the
original hardware release 3.2 CBS can be downgraded from firmware
3.4.0 to 3.2.0. However, ftpdl.exe reports an error and the CBS remains
unaffected if a revised hardware release 3.2 CBS is downgraded from
firmware 3.4.0 to 3.2.0. If TFTP bootload feature is used to downgrade
the firmware, the CBS ignores the bootload request and remains
unaffected.
Updating the Firmware
Periodically updates may be required to add enhancements or correct
problems in the CBS firmware.
Upgrade all CBS firmware to the latest version available. The latest
firmware release can be found at www.ncr.comÆSupport ÆDrivers
and PatchesÆRetail Support FilesÆRealPrice Support Files.
Note: Check to make sure that the customer does not have a special
firmware version requirement.
Caution: Some customers may not allow firmware to be installed
until it has been integration tested.
The 7730 Firmware Management System – “Firmware Bootloader” –
(released with firmware version 3.3.4) facilitates firmware updates to
the 7730 Communications Base Station (CBS). The Firmware
Bootloader consists of software components that reside on both the
RealPrice System Server and 7730 CBS units.
Upgrading firmware from 3.2.x and earlier to 3.3.4 requires upgrading
to firmware version 3.3.4 first using the method (ftpdl) described in the
previous section “Updating CBS's Firmware Image (ftpdl)”.
The Firmware Bootloader supports:
• Simultaneous firmware update to multiple CBS units
• CBS recovery following application block firmware corruption
• Diagnostic features to support flash update failure troubleshooting
Chapter 3: Maintenance 3-17
The Firmware Bootloader provides a simple method for updating 7730
CBS firmware. The following steps outline the method for firmware
update:
• A CBS evaluates its firmware at boot time and determines if a
firmware update is necessary. This determination is made by
sending a TFTP request for the RealPrice boot file and comparing
the internal firmware version of the CBS with the target firmware
version information contained in the boot file.
• The CBS initiates the firmware update, if necessary, by making a
TFTP request for the new firmware image.
• Upon completion of the file transfer, the CBS replaces its
application firmware with the newly acquired firmware image.
• Finally, the boot firmware transfers control to the application
firmware, and the CBS begins normal operation.
Steps for completing firmware update
1. Configure the DHCP server, if using DHCP.
This is an optional step. DHCP server configuration is discussed at
the end of this section.
2. Customize the boot file, if necessary.
Two files are required to accomplish a firmware update:
• an application image, the binary image that contains the
machine instructions for normal CBS operations. Application
images are non-editable binary files and are at least 700K bytes
in size.
• a boot file , an XML file that specifies rules and instructions for
the firmware update.
Note: A default boot file and application image is distributed with
each firmware release.
3-18 Chapter 3: Maintenance
Boot File
Boot files are small, editable XML-formatted files of 1K bytes or less
and contain the following information:
• Update instructions indexed by CBS’ current firmware revision
• Application image filenames
• Application image revision information
Boot files may contain wildcard information to select a group of
target CBS units with similar characteristics. Boot files may
stipulate a firmware upgrade to a newer revision or a downgrade
to an older revision.
The user may wish to modify the boot file to specify a different
location for the firmware image or specify new rules for the update.
The boot file may be modified with any basic text editor. A sample
boot file is shown:
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl"
href="dnbootloadconfig.xsl"?>
<!DOCTYPE rp7730 SYSTEM "dnbootloadconfig.dtd">
<rp7730>
<ImageFilename>rom334.bin</ImageFilename>
<ImageVersion>3.3.4</ImageVersion>
<TargetVersion>3.*.*</TargetVersion>
</rp7730>
• ImageFilename is the file name of the firmware image to be
used to upgrade the CBSs firmware level.
• ImageVersion is the new firmware revision level.
Note: ImageFilename and ImageVersion versions must match for
successful firmware upgrade as shown in the following example:
...
<ImageFilename>rom334.bin</ImageFilename>
<ImageVersion>3.3.4</ImageVersion>
...
Chapter 3: Maintenance 3-19
The ImageFilename indicates that the firmware image is 3.3.4 and
ImageVersion reflects the same version.
TargetVersion is the firmware version that is targeted to be
upgraded. Wild card characters can be used.
3. Place the boot file and firmware image in the dnet\firmware
directory.
4. From a command prompt, type dnloadcbsfirmware. The
following screen displays if successful.
Note: dnloadcbsfirmware takes care of the stopping and starting
RealPrice as well as flashing firmware. The process will take a few
minutes. Please be patient while the entire process is carried out.
3-20 Chapter 3: Maintenance
5. If the firmware upgrade was unsuccessful, the following screen
displays.
The table below shows the possible errors while upgrading the CBS.
Error Code Description
0 Success
1 an unrecognized failure occurred
3 No DHCP server responded to boot request
4 The TFTP server address is unknown
5 the TFTP server did not reply to request
7 the TFTP server could not find the requested
boot file
8 critical information is missing from the boot
file
9 the TFTP server could not find the requested
image file
10 the new image file and boot file information
Chapter 3: Maintenance 3-21
do not match
11 the new image file sumcheck is bad
12 the new image is incompatible with the
hardware
13 an error occurred while writing to flash
memory
Note: dnloadcbsfirmware attempts to upgrade the CBSs three times. If
CBSs report failure to upgrade after all attempts, power cycle the target
CBS units. The user may manually power cycle the CBSs or initiate a
soft reboot.
Manual Power Cycle
To manually power cycle the units, unplug the CBS Power Supplies
from the AC source. Reconnect each power supply starting with the
power supply connected to the primary CBS. Continue
reconnecting each power supply.
Soft Reboot
To initiate a soft reboot, from a command prompt, type
dnCBSreset. It takes a few minutes to reset the CBSs and
complete the firmware update.
6. Optionally, examine the target CBS units to confirm that the
firmware update was successful.
Use the utilities dnCBSFirmware and dnCBSDiags to confirm the
success of the firmware update.
dnCBSFirmware
From a command line prompt, type dnCBSFirwmare to display
the ARM version (firmware version level) for each CBS in the
RealPrice system.
If the firmware update has been successful, the DOS window
displays all of the CBSs with the correct firmware level listed.
3-22 Chapter 3: Maintenance
If the result of dnCBSFirmware shows different versions among
the CBSs or no change to the firmware version, run dnCBSDiags to
determine the error.
dnCBSDiags
From a command line prompt, type dnCBSDiags to view the
diagnostics for each CBS.
Review the Bootloader Status entry which reports the status of the
Bootloader update process. 0 (success) indicates that the process
has been successful.
7. Troubleshoot problems with the firmware update.
Verify that the TFTP Server is installed and configured properly.
See section “NCR TFTP Configuration” later in this chapter.
Verify that the DHCP Server is configured properly.
Verify that the boot file is correctly formatted and defines the
correct file to use for the upgrade.
Note: The process may need to be repeated to successfully update the
firmware.
Chapter 3: Maintenance 3-23
DHCP Server Configuration
DHCP is optional and depends on how the RealPrice system is
configured in a store environment.
If the TFTP server is running on a different server than the RealPrice
server or if a different TFTP server is used, DHCP needs to be
configured.
To configure the Windows NT 4 Server DHCP server to work with the
NCR TFTP server, vendor specific information needs to be configured.
1. Open the DHCP Manager.
2. Select DHCP OptionsÆScope.
3-24 Chapter 3: Maintenance
3. Select 043 Vendor Specific Info and select Add to make it an active
option.
4. Select Edit Array button.
5. Enter the following values in the Numeric Value Array Editor:

60 Second Octet for IP address of TFTP server
39 Third Octet for IP address of TFTP server
205 Fourth Octet for IP address of TFTP server
0 Required
6. Select OK to save the values.
Updating Firmware Before RealPrice Base Software Installed
Under normal circumstances a user utilizes server components and
diagnostic features released with RealPrice Base software package;
however, a firmware update may be accomplished before the base
software is installed. The following limitations and restrictions apply:
A DHCP server must be configured to specify option 43 (Vendor
Specific Info) as described in the previous section.
A native TFTP server must be present. NCR TFTP Server ships and is
installed with the RealPrice Base software package.
No diagnostic capabilities are available to assist with troubleshooting.
3-26 Chapter 3: Maintenance
To use DHCP as a means of initiating a firmware update, the CBS
requires that a DHCP server specify a TFTP server name using option
43. The DHCP server must allow for specifying option 43 as an ASCII
string representing the TFTP server’s IP address in standard dotted
decimal notation. See DHCP Server Configuration above.
Using Static IP Addresses
If CBSs are configured to work without a DHCP server (static IP
addresses), each CBS uses the address of the RealPrice server as the
TFTP server address.
To use this alternate method, the CBS must already be aware of the
RealPrice server.
This can only be accomplished if the CBS first establishes a connection
with the RealPrice server during normal operation and stores its
address in non-volatile memory.
At boot time, the CBS immediately goes to the application image and
begins normal operation in the event that it cannot determine the TFTP
server address.
NCR TFTP Configuration
When the RealPrice Base software is installed, the NCR TFTP Server is
installed as a service configured to start automatically on reboot. If a
different TFTP server is installed and used, the NCR TFTP service
needs to be disabled.
The 7730 Firmware Management System (Firmware Bootloader) uses
NCRTFTPS to flash application image, the binary image that contains
the machine instructions for normal CBS operations.
The NCR TFTP Server can run as either a Windows NT service or an
application.
Chapter 3: Maintenance 3-27
Command Line Parameters
The NCR TFTP Server does not normally provide an interactive user
interface when running as a service. It is stopped and started like other
NT services, controlled through the Services dialog box in the Control
Panel. It may also be started from the command line.
The NCR TFTP Server supports the following command line
parameters (preceded by ‘-‘ or ‘/’):
• ? – displays command line parameter help
• help – displays additional product information
3-28 Chapter 3: Maintenance
• install – installs the service
• remove – removes the service
• status – displays version information and service status
• start – starts the service
• stop – stops the service
• parameters – displays/changes parameters
If NCR Fit Client is installed, RealPrice overwrites the NCR TFTP
server and increases the maximum number of sessions for TFTP server
from default 20 to 40.
Chapter 3: Maintenance 3-29
No changes need be made to Default Directory unless running TFTP
server on a different server than RealPrice server.
• application – run executable as an application on Windows NT 4.x
