4Installation Guide MDS 05-2873A01, Rev. D3 Review Draft 3—12/17/01 ABOUT THIS MANUAL This guide presents installation and initial operating instructions for the MDS iNET 900™ transceiver. Following installation, we suggest keeping this guide near the equipment for future reference.The scope of this manual is limited to the safe and effective installation of the unit in typical office or non-hazardous industrial settings. Users who require optimization of the equipment’s capabilities and oper-ating range should read the MDS iNET 900 Network Administrator’s Manual , P/N 05-xxxxA01. This manual provides more in-depth infor-mation on antenna selection and optimization, and extensive coverage on user-controllable parameters and diagnostic tools.Many of the essential installation information is contained on the Installation Reference Chart found at the center of this manual. PRODUCT DESCRIPTION The MDS iNET 900 transceiver (shown on the cover) is a data radio transceiver designed for to support wireless data networks.The MDS iNET 900 transceiver is designed to provide network man-agers with a easy-to-install wireless local area network (LAN) services with plug-and-play hardware. The unit can be reconfigured for any one of three standard operating arrangements; some require the use of electronic keys (alphanumeric code) purchased from MDS. The model descriptions reflect their operating mode capabilities. The core data interface services are 1. Ethernet, 2. Serial, and 3. Serial and Ethernet. (See Table 1 on page 5 for a summary of core interface services.)Three model configurations are available; they are:1. Ethernet Bridge—Supports Ethernet traffic only2. Serial gateway—Supports serial traffic only (Encrypted over IP protocol)3. Access Point/Dual Gateway—Supports Ethernet and serial data simultaneously
MDS 05-2873A01, Rev. D3 Installation Guide 5 Review Draft 3—12/17/01 The MDS iNET 900 transceivers serve as either an “Access Point” or “Remote Gateway”. An Access Point is a wireless hub that provides connectivity into a wired Ethernet LAN/WAN. From a radio perspec-tive, an Access Point also serves as the radio network’s “master sta-tion” providing synchronization signaling for associated iNET 900 Remote Gateway radios. INSTALLATION PLANNING This section provides tips for selecting an appropriate site, choosing an antenna system, and reducing the chance of harmful interference. General Requirements There are three main requirements for installing the radio—adequate and stable primary power, a good antenna system, and the correct interface between the transceiver and the data device. The center Installation Reference Chart shows a typical Remote Gateway instal-lation. Table 1. i NET 900 Models and Data Interface Services Model Oper.

6Installation Guide MDS 05-2873A01, Rev. D3 Review Draft 3—12/17/01 Access Point stations are similar, but typically they use an omni-direc-tional antenna and a Local-Area Network (LAN) or a Wide-Area Net-work connected to the LAN port. The Access Point iNET radio provides a connection to the wired network for devices attached to the Remote Gateways.Antennas are a vital link in the system; they must be chosen and installed correctly. The MDS iNET 900 Network Manager’s Manual provides details on choosing a site and making antenna selections INSTALLATION A typical transceiver product shipment consists of an iNET 900 trans-ceiver and a manual. Check the contents against the packing list attached to the outside of the shipping box. Below are the basic steps for installing a i NET 900 transceiver. Should further information be required, see “IN CASE OF DIFFICULTY...” on page 14 of this manual for information on contacting the factory. You will also find support information at the Microwave Data System Web site at www.MicrowaveData.com on the Internet. NOTE: It is recommended that the Access Point station be installed first. In this way, it will be possible to quickly check the operation of each associated Remote Gateway unit as it is placed on the air. MDS iNET 900 transceivers are shipped from the factory set to the “Remote Gateway” mode unless they are marked differently. Step 1—Mount the Transceiver Mount the transceiver to a stable surface. (Fasteners/anchors/screws are not supplied unless specified when the order.) Four threaded holes are located on the bottom of the radio that are suitable for connecting mounting hardware. Use 6-32 x 1/4 inch screws to attach mounting hardware to the bottom of the radio.
MDS 05-2873A01, Rev. D3 Installation Guide 7 Review Draft 3—12/17/01 Screws used to hold the mounting brackets to the radio should be 5⁄16 inch (8 mm) long or shorter to prevent damage to the radio’s internal PC board. If these screws are replaced for any reason, the new screws must not exceed this length. The radio’s case is made of a durable cast-aluminum, however, the use of the wrong sized screws can damage the screw sockets on the cover. Step 2—Install the Antenna The antenna and i NET 900 unit should be mounted with the antenna a minimum of six inches (15 cm) from other equipment, especially metallic objects. NOTE: Radio frequency energy generated by the i NET 900 can interfere with the operation of nearby low-level RTU circuits and change the reported values of the data being monitored. For this reason, the antenna should be mounted at least 10 feet (>3 meters) from the RTU, sensors and other components of the system.General information on the selection and installation of antenna sys-tems is provided in the MDS iNET 900 Network Manager’s Manual . Step 3—Measure & Install Primary Power The primary power at the transceiver’s power connector must be within 10.5–30 Vdc and be capable of continuously furnishing up to 500 mA. The optimum voltage is 13.8 Vdc. Be sure to observe proper polarity as shown in Figure 1. A power connector is provided with each radio suitable for use with pigtail leads. Invisible place holder Figure 1. Primary Power (DC) Polarity The radio is designed to be used only in nega-tive-ground systems. Make sure the polarity of the power source is correct. Reverse polarity will dam-age the iNET 900’s circuitry and will result in per-manent damage to the unit.CAUTIONPOSSIBLEEQUIPMENTDAMAGECAUTIONPOSSIBLEEQUIPMENTDAMAGE
8Installation Guide MDS 05-2873A01, Rev. D3 Review Draft 3—12/17/01 The power supply used with the transceiver should be equipped with overload protection (NEC Class 2 rating), to protect against a short cir-cuit between its output terminals and the transceiver power connector. Step 4—Review the Radio’s Configuration There are two essential settings for i NET 900 transceivers that should be known before placing the radio into service. They are: Radio Operating Mode —Access Point or Remote Gateway Network Name— Unique name of the radio network that is used to generate the hopping pattern. NOTE: Transceivers are normally shipped from the factory config-ured as a Remote Gateway. Unit IP Address —Must be a unique number to allow for IP access through the Ethernet Port. Transmitter Power Output Level —Default is 1 Watt. Adjust as necessary for compliance with FCC guidelines. NOTE: A unique IP address is important if the radio’s LAN (Ethernet) port will be used for IP-based data communica-tions or for unit configuration. NOTE: The COM1 port’s only function is to provide access to the iNET 900’s management system. COM2 is not functional at this time.The following is a summary of the installation procedure. For more detailed instructions on using the menu-based COM1 and the HTTP/Bowser interfaces, please read the MDS iNET 900 Network Administrator’s Handbook . Procedure a. Connect a personal computer’s serial communications port (COM1 or COM2) to the COM1 Port connector on the radio transceiver. (See the I nstallation Reference Chart for location. Data defaults: 19,200 kbs/8N1.)b. Launch a terminal emulator program, such as HyperTerminal, on the computer.c. Depress the ENTER key. The radio will respond with the start-up screen of a text-based Management System.
MDS 05-2873A01, Rev. D3 Installation Guide 9 Review Draft 3—12/17/01 d. A login with password will be required to make any changes to the radio. (Default = admin )e. Select the desired options to review existing settings and to initiate necessary changes such as the IP address and other network parameters. Changes are saved in the unit’s flash memory.f. Repeat the above steps for each transceiver in the network. Basic i NET Unit Parameter Defaults The table on the center Installation Reference Chart provides a sum-mary of basic operating parameter’s range of and default values. All of these are available through the i NET’s Management System acces-sible through a terminal emulator connected to the COM1 port. Step 5—Connect the Data Equipment Connect Ethernet/IP-compatible equipment data equipment to the transceiver’s LAN port. The port supports only 10BaseT.Use only the required pins for the application—do not connect any-thing to unused pins. Use a straight-through Ethernet cable to connect to a hub or a crossover cable to connect directly to an Ethernet station or RTU. See the Installation Reference Chart in the middle of this guide for pinout information. Remote Gateway —If the radio network seems to be operating prop-erly based on observation of the unit’s LEDs, connect the user data equipment to the LAN port. Use the IP PING command to verify the communications link integrity with the Access Point unit. Access Point —Connect the WAN/LAN to the LAN port of the radio. LED Indicators A table of LED functions can be found on the center Installation Ref-erence Chart .
10 Installation Guide MDS 05-2873A01, Rev. D3 Review Draft 3—12/17/01 Step 6—Check for Normal Operation a. Observe the transceiver LED status panel (See the Installation Reference Chart ) for the proper indications. In a normally operating system, the following LED indications will be seen within 30 seconds of start-up:• PWR— Lit continuously• LINK —Blinks intermittently at Remote Gateways and contin-uously on Access Point stations.• LAN —On indicates it connected to a good Ethernet cable. Blinks (flickers) with data activity.b. Check the received signal strength indicator (RSSI) for an adequate signal level from the radio network’s Access Point station. (RSSI available through the iNET Management Sys-tem) It may be necessary to reposition the gateway radio’s antenna for better reception/signal strength, or if a directional antenna is used, rotate it until the signal is optimized.See the Installation Reference Chart for details on the LED functions and chart of Management System menus. If all checks out OK, you are done with the installation. Congratula-tions! Performance Optimization After the basic operation of the radio has been checked, you may wish to optimize its performance using some of the suggestions given here. The effectiveness of these techniques will vary with the design of your system and the format of the data being sent.Complete instructions on using the unit’s configuration options refer-enced within this section are can be found in the MDS iNET 900 Net-work Manager’s Manual.
MDS 05-2873A01, Rev. D3 Installation Guide 11Review Draft 3—12/17/01TROUBLESHOOTINGIt is best to begin troubleshooting at the Access Point station, as the rest of the system depends on the Access Point for polling instructions and synchronization data. If the Access Point station has problems, the operation of the entire network will be affected.All radios in the network must meet these basic requirements:•Adequate and stable primary power•An efficient and properly aligned antenna system• Secure connections (RF, data & power)• Proper programming of the radio’s operating parameters, especially Mode selection (Access Point/Remote), Network Name, and IP Network Address• The correct interface between the radio and the connected data equipment (proper cable wiring, data format and timing).Table 2 on page 12 provides suggestions for resolving system difficul-ties that may be experienced in the radio system. If problems persist, contact the factory for further assistance. Refer to the inside back cover of this guide for contact information.

Check for the proper supply voltage at the power connector.b. Cycle the power and wait for the unit to reboot. (≈ 30 seconds)Interference is suspected. a. Verify that the system has a unique network name. A nearby systems (Access Point station) with the same network name will cause interference.b. If omnidirectional antennas are used on, consider changing to directional antennas. This will often limit interference to and from other stations.c. The installation of a filter in the antenna line may be necessary. Consult the factory for further assistance.The LINK LED does not turn on. a. Check for secure interface connections at the radio and the connected device.b. Check the antenna, feedline and connectors. Reflected power should be less than 10% of the forward power reading (SWR ≈2:1 or lower).c. No synchronization with Access Point, or poor overall performance. Check RSSI level.Cannot pass IP data to WAN. a. Use the PING command to test communication with iNET units in the local radio system.b. If successful with local PING, attempt to PING an IP unit attached to an iNET radio.c. If successful with the LAN PINGs, try connecting to a known unit in the WAN.
