3INSTALLATIONGeneralMOSCAD-M SAFETY SUMMARYThe MOSCAD-M should be installed by qualified and authorizedtechnicians. If the installation involves high-voltage connections,technicians must be specifically qualified to handle high voltage.This equipment was tested with cables 3 meters in length. If longercables and/or cabinets are used, the installer is responsible for makingsure that the installation complies with the requirements of the relevantstandard.The product is a radio accessory. The installer must make sure that theradio connected to the system has all required approvals and that theinstallation meets the requirements of the standard. This equipment is abase station unit and complies with the FCC base station requirements.The antenna must be installed outdoors.Power Connections:This device accepts 9-30V DC input, maximum 2.5A @15V DC.This chapter covers the following installation procedures:• Wall mounting• Connections• Backup Batteries• MiscellaneousWall MountingThe dimensions of the unit are: width – 21.5 cm (8.46"), height – 18.5 cm (7.28"), depth – .85cm (.33"), weight – 1.5kg maximum (see Figure 2).
Installation4Figure 2Dimensions of MOSCAD-M RTU Plastic CaseThe unit can be installed on screws or on DIN rail mounting. Before installing theMOSCAD-M RTU, verify that there is sufficient space around the unit. Allow 20 cm (7.87")from the bottom of the box for the TB connectors. When an RF connector is attached (internalradio models), allow for an extra 10 cm (4"): 2.02 cm (.8") from the top of the box for the RFconnector and 8 cm (3.15") for the wires. For models with external radios, allow 8 cm (3.15").Wall Mounting with ScrewsThe MOSCAD-M can be mounted on the wall using screws, as shown in Figure 3.1. Secure two screws (maximum head size 0.9 mm) on the wall, 105 mm apart.2. Hang the unit on the screws, fitting the two cavities on the back cover of the unit over thescrews (see Figure 3).The screws used should not protrude from the wall surface by more than 6 mm or by less than4 mm.
Installation5Figure 3Installation of MOSCAD-M – Screw MountIt is also possible to attach the MOSCAD-M to the wall using the small screw hole at thebottom of case, though this requires dismantling the RTU, which is generally discouraged.Consult Motorola service personnel before opening the MOSCAD-M casing. To mount theRTU:1. Open the case and dismantle the parts of the MOSCAD-M.2. Secure the back of the case against the wall using a screw whose diameter is less than3.5 mm and head size is at least 5.5 mm.3. Reassemble the parts of the MOSCAD.Before beginning any disassembly or reassembly procedures, youshould be adequately grounded to prevent damage to static sensitivedevices in the unit.Wall Mounting on DIN RailFor mounting the RTU on a DIN rail, two universal foot elements (Phoenix Connectors MFCPIN UMK-FE) are required. To mount the unit, proceed as follows:1. Slide the two foot elements into the recesses on the back cover of the unit as shown inFigure 4. Press until they click behind the snaps that secure their placement. (See zoomedimage in Figure 5.)
Installation6Figure 4DIN Rail AttachmentFigure 5DIN Rail Attachment-Foot Element Snap-in (Enlarged)2. Press the unit onto the DIN rail, using both universal foot elements. The elements can beused on DIN rail 35 mm and G rails. (See Figure 6).Figure 6MOSCAD-M Mounted on DIN RailSNAP
Installation7ConnectionsVerify that all power and ground connections are made inaccordance with local standards.Ground ConnectionConnect the grounding cable directly to the protectivegrounding pins 9 and 10 (PGND) in the main power-in connector(see TB1 in Figure 9).Power ConnectionsThe unit can be connected directly to a 9-30V DC source through the main Power-In connector(see Figure 9) where Pin #1 is + (positive) and Pin #2 is – (negative).It is recommended to connect the main power supply to the unitwith a 3.5 amp fuse on the cable.Backup Battery ConnectionThe RTU has a special chamber for 3 “C” alkaline backup batteries (not supplied) that areused to retain the unit’s RAM and Real Time Clock in power fail situations.Internal Radio Connection - antennaThe internal radio is connected through the 14-pin connector on the Main board inside theplastic housing. Its power is driven from that connector. When an internal radio is installed,Port 3 of the radio cannot be used.External Radio ConnectionConnect the external radio to Port 3 (see Figure 9). Verify that the radio button is set to ON.The radio signals are driven from the AUX connector in Figure 9.It is recommended to replace the external radio only when theunit is powered off.
Installation8If the external radio is connected to an outside power supply,first power on the unit, and then power on the radio.The auxiliary power supply (maximum 2A) can be changed to 6V,6.5V, 7.5V, 8V, 9V or 9.6V DC by changing the setting of the P11jumper located on the Main board. (See markings on the board.) Toset the power to 8V, remove the jumper and save for future use.This is usually set in the factory according to the external powersupply of the radio. The default setting is 9V DC. To change thevoltage, follow the disassembly instructions in Appendix C, place thejumper and reassemble.Line Communication ConnectionLine Communications are connected through Ports 1 or 2 (see Figure 9.) Port 1 can beprogrammed as RS485 (1A) or RS232 (1B). Port 2 can be programmed as RS232.
Installation9Installation of Backup BatteriesThe backup battery should not be installed before the unit isconnected to the main power supply. This may cause thebattery to drain.1. Place 3 “C” size alkaline batteries into the carton cylinder, each in the same direction, asshown in Figure 7 below.Figure 7Backup Battery Cylinder and 3 Backup C Batteries2. Place the cylinder with the batteries into the battery case in the direction indicated on theunit (see Figure 8 below).Figure 8Installation of Backup Batteries
Installation10MiscellaneousOpen the Case DoorTo open the case door properly, press the two clips (latches) and pull the wing to an openposition. The cable cover is opened counter-clockwise to expose the cable connections andthe backup battery cover is opened clockwise to expose the battery housing.Close the Case DoorTo close the case door properly, press until the latch clicks. Note that if the batteries in thehousing are not inserted properly, the backup battery cover door may not close. If the cableconnections are not threaded properly through the cable holes, the cable cover may not close.Antenna PlacementThe antenna is connected to the internal radio through the snap hole on top of the plastichousing (see Figure 9). For models with external radios, screw the antenna onto the radioantenna connector.An antenna placed on top of the plastic housing producesstrong electromagnetic fields that could be harmful to theelectronics of the MOSCAD-M RTU and to people in the vicinity.Fixed Site AntennasThe antenna installation must comply with the following requirements in order to assureoptimal performance and make sure human exposure to radio frequency electromagneticenergy is within the guidelines set forth by the local regulations.• The antenna must be mounted outside the building.• Mount the antenna on a tower if at all possible.• If the antenna is to be mounted on a building, then it must be mounted on the roof.• As with all fixed site antenna installations, it is the responsibility of the licensee to managethe site in accordance with applicable regulatory requirements. This may requireadditional compliance actions such as site survey measurements, signage, and site accessrestrictions in order to ensure that exposure limits are not exceeded.
11THE MOSCAD-M UNITOverviewThe MOSCAD-M RTU (shown below) contains power connections, line communication ports,internal/external radio interfaces, radio modems and I/Os.Figure 9MOSCAD-M Unit

Port 3 cannot be used when an internal radio isinstalled.ConnectorsThe MOSCAD-M RTU has the following connectors available (see Figure 9):RS485 Port 1A (RJ45, 4 pin)RS232 Port 1B (RJ45, 8 pin)RS232 Port 2 (RJ45, 8 pin)External Radio Port 3 (RJ45, 8 pin)AUX out for external radio power supply (2 pin)Power In/Solid State DO (10 pin) - TB1DO (10 pin) – TB2DO/DI (10 pin) – TB3DI (10 pin) – TB4DI/AO (10 pin) – TB5AI (10 pin) - TB6The MOSCAD-M RTU has the following internal connectors.Internal radio connector (14 pin)Backup Battery connector (2 pin)I/O Expansion connector (26 pin)Controls and IndicatorsThe push-button is used to activate the LED panel, to toggle the LED panel so that it displaysthe status of the CPU or of the I/Os, to initiate software downloading to the CPU, and to eraseUser Flash memory and RAM.
The MOSCAD-M Unit13LED ControlDisplay On/AdvanceWhen the display is off, pressing the push-button once, momentarily, activates the display.Every consecutive momentary depression of the push-button advances the display to the nextpage, in the following order: CPU > IO1 (I/O Page 1-DI) > IO2 (I/O Page 2-DO) > IO3(I/O Page 3-AI) > Page 4 (AO) > Page 5 (User Application Controlled) > Page 6 (HardwareTest Controlled). The next depression of the push-button returns the display to the CPU.Display OffThe display can be programmed using the Configurator Site Configuration tool to turn offautomatically after a predefined period of time if the push-button has not been pressed.LED TestWhen the push-button is pressed continuously for a few seconds, all LEDs light upsimultaneously. When the push-button is released, the LEDs turn off.User Flash EraseAfter power-up, all LEDs light up. To erase the User Flash, press the push-button while theLEDs are lit. All the LEDs flash three times. Now, release the push-button.Alternatively, press the push-button continuously for at least 40 seconds at any time to erasethe User Flash.User RAM Erase (Cold Restart)Turn off the power supply, while the push-button is depressed. The next time the unit ispowered up, it will perform “cold restart”, which means all data stored in the RAM is erased.Note: The data that is stored in the Flash (i.e. applications, site configuration, and networkconfiguration) will not be erased.System Software DownloadingDuring power up, press the push-button continuously. This will cause the unit to enterbootstrap downloading mode, in which the FLASH is programmed from a PC connected toPort 1 of the MOSCAD-M. The CPU LED will begin to blink at 1 Hz, indicating that the CPUhas entered bootstrap downloading mode. If after 120 seconds no bootstrap software is loadedand executed, the normal power-up procedure is performed.CPU ResetTo reset the CPU when a backup battery is not installed, turn the power supply to the unit offand on again. When a backup battery is installed, follow the Cold Restart method describedabove.

As long as the input power is above6V DC, the unit is still powered from the main power supply input. If the input power dropsbelow 6V DC, the unit will use the backup battery to preserve the contents of the RAM andReal Time Clock (RTC) data. In this case, the unit is in Low Power Sleep mode and not inReset mode. This means that the status of outputs 1 to 8 is preserved.The battery will retain the data for at least 70 days (cumulative). Power consumption from thebackup battery will be <5mA @ 4.5V DC.If no backup battery is detected, or if the backup battery falls below 3.1V DC (power fail), theunit will shut down until power is restored. In this case, the RAM and Real Time Clock(RTC) data will not be retained. LED 4 (BATT) will indicate when the backup battery voltagedrops below 3.5V. This indication is also available for the user application. Under thesecircumstances, the SS1 and SS2 Solid State switches are turned off even if they were set toindependent operation mode.
The MOSCAD-M Unit30Power SupplyThe MOSCAD-M can be operated from an input of 9-30V DC. The minimum input level isdetermined by the output voltage level required for the AUX/Internal radio.The table below describes the minimum input levels for the different settings:OutputPowerMinimumInput Power696.5 97.5 98109 10.59.6 11.5The AUX/Internal radio power is set by a jumper on the Main board.

31POWER MANAGEMENTOverviewThe MOSCAD-M includes a Power Management feature which is controlled by the userapplication. The unit can operate in four power save modes:• Power Management Disabled (in which the entire system is operational and no powersaving technique is used)• Run mode (in which the entire system is operational and power is provided only to activeports of the unit)• Idle Sleep mode (in which the unit uses low power)• Low Power Sleep mode (in which the unit is basically off)When the MOSCAD-M is powered up, it operates in Run mode. If all application and systemtasks are idle, and the Power Management Feature is enabled, the RTU will enter Idle Sleepmode in order to conserve power. The unit will return to Run mode if one of several Wakeupevents occurs.If the input power falls below 8.9V, the unit automatically enters Low Power Sleep mode. Theunit will return to its previous mode (Run or Idle Sleep) when the input power returns to atleast 9.3V.The Power Management Feature, which is disabled by default, canbe enabled by the user application.Run ModeIn Run mode, tasks will execute, suspend and exit, as necessary. In order to execute, eachapplication and system task will request a ‘visa’ from the ‘visa manager’. When the tasksuspends or exits, its visa is returned. If all visas in the system have been returned, the unitcan enter Idle Sleep mode. A task can choose to operate without a visa; however, it may beforced into Idle Sleep mode by the system when all other tasks have returned their visas.Before a task suspends itself, it will define those Wakeup events which will cause it to wakeup. When the requested Wakeup event occurs, the task will receive a signal and awaken (evenif the Power Management feature is disabled.) If one of these events occurs while the systemis in Run mode, it will prevent the system from entering Idle Sleep mode.Total power consumption from the main power supply in Run mode is at most 150mA @ 14VDC. Typically, power consumption will be 50mA. The additional power consumed by theradio in Run mode depends on the radio type and will be at least 40mA.
Power Management32Sleep ModeThe MOSCAD-M will enter Sleep mode in the following situations:• Idle Sleep - All system and application tasks are idle.• Low Power Sleep - The main power supply falls below 8.9V.Power consumption is minimized by switching off the power of all non-active circuits anddevices (communications inputs and outputs, etc). In Sleep mode, the unit’s powerconsumption will be <5mA @ 14V DC.In Sleep mode, the current consumption is <5mA. However, thepower consumption will be significantly higher if the AO is enabled orthe radio port is defined as a Wakeup event. If Port 3 is enabled inSleep mode, the power consumption will be 30mA and the radiopower consumption will be at least 40mA, for a total of at least70mA.When entering Idle Sleep mode, the following power supplies are disabled:• Radio/auxiliary power supply• AI power supply• AO power supply• SS1 and SS2 switches power supply• 3.3V Peripheral power supply• Port 1 UART, Port 2 UART power supplyOne or more of these power supplies might be left active, depending on the type of Wakeupevents that are selected. (See Wakeup events below.)The AO power supply will not be disabled in Idle Sleep mode if avalue is set in the AO.By default, The solid state SS1 and SS2 switches are controlled bythe Power Management feature. However, it is possible to configurethem to an independent operation mode where they are controlled(enabled/disabled) by the user application only. If the unit enters LowPower Sleep mode, SS1 and SS2 will be turned off even if set toindependent operation mode.If one of several preprogrammed Wakeup events occurs, the unit will return from Idle Sleepmode to Run mode. Those tasks which requested the Wakeup event will wake up and anyother tasks will remain suspended.If, however, the unit is in Low Power Sleep mode, it will not respond to Wakeup events.When a power level of 9.3V is restored at the power input, the unit will revert to its previousmode.
Power Management33Wakeup EventsWhen enabling the Power Management feature, the MOSCAD-M user should configure thoseWakeup events that will wake up the unit from Idle Sleep mode.The possible Wakeup events are:• DI WakeupWhen a Change of State occurs in DI1 and/or DI2 and/or DI3, a Wakeup event isgenerated.• Push-Button WakeupPressing the push-button when the unit is in Idle Sleep Mode will cause a Wakeup event.(The push-button is enabled at all times.) The unit will enter Run mode for at least 30seconds.• Communication Port WakeupA signal received at one of the unit’s three ports, if designated by the user as a Wakeupevent, will cause the unit to wake up.Port 1 Wakeup: when data stream is received.Port 2 Wakeup: when data stream is received.Port 3 Wakeup: when an indication for an active channel (channel monitor) is received.• Periodic (Internal) WakeupThe Real Time Clock (RTC) will cause the unit to wake up every 5 minutes to reset thewatchdog timer.The user application can request a wakeup after a certain period of time or upon receipt of aspecific Wakeup event. This will then cause the system tasks (and the unit) to wake up and theunit to return to Run mode.See the ‘C’ Toolkit for MOSCAD Family RTUs manual (68P02956C75) for details on thesystem functions which provide these services to the application.For more information on the Power Management Feature, see the MOSCAD-M RTUConfigurator User’s Guide (68P02961C55).
34ETHERNET INTERFACE OPTIONOverviewThe Ethernet interface option is used as a communication link for the MOSCAD-M units withLocal Area Networks (LAN). The Ethernet interface option supports TCP/IP protocol on aTwisted Pair (TP) connector, with automatic polarity correction.External Ethernet Interface UnitEnclosed in a plastic box, the external Ethernet Interface unit provides an RS232 port forconnection of MOSCAD units to LAN. The external Ethernet unit is powered by 9-15V DCand has indication LEDs on its front panel. The system software of the external Ethernet unitcan be upgraded using the Ethernet Interface Downloader program.The following figure depicts the front panel of the Ethernet unit.Figure 18External Ethernet Unit – Front PanelThe Ethernet indication LEDs are:• TX - Ethernet Transmit• RX - Ethernet Receive• LI - Ethernet Link IntegrityThe RS232 indication LEDs are:• TX - RS232 Transmit• RX - RS232 Receive• CM - RS232 Channel MonitorPower LED12V DC (9-15V) Power inletEthernet twisted pairconnectorEthernet indication LEDsRS232 indication LEDsRST - ResetDIAG - Diagnostics Data PresentRS232 Connector to RTU

Set up the MOSCAD-M Configurator PC as described below, then follow thedebugging instructions in the ‘C’ Toolkit for MOSCAD Family RTUs manual.MOSCAD-M BoardThe kit consists of a special MOSCAD-M board, specifically built for debugging. The systemsoftware (system.krl) is burned into the flash memory at the factory. Another system file(MmxyyD2.krl) is available with the Debug System Installation (FVN9779) MOSCAD-MConfigurator and must be downloaded before using the Microtec XRAY debugger.The debug board has no plastic housing and all components are visible. Next to the push-button there are two additional buttons which do not exist in the standard MOSCAD-M. Theleftmost button is Reset. The rightmost button is NMI (Non Masked Interrupt). The NMI (orCTRL+C from the PC keyboard) will stop the program.Two megabytes of RAM are installed in the debug board to enable downloading the systemsoftware from the PC to the unit.
Appendix B: Models and Accessories43Debug SetupBy default, downloading from the PC to the unit is done via Port 2. When the unit is firstpowered up, LED 12 (CM2) should be lit, indicating that the debugger should be downloadedvia Port 2.In order to connect to Port 1, a modified system file must be downloaded to the flash. This fileis available from the factory.To set up the system for debugging, do as follows:a) Compile and link your application using Microtec tools.b) Connect the MOSCAD-M Configurator to the debug board as you would the standardMOSCAD-M board.c) In the Site Configuration utility, set Port 2 to Not Used.d) Download the site configuration.e) Connect Port 1 of the RTU to the COM port of the PC.f) Switch off the RTU, then switch it on again, while the push-button is pressed. The systemwill then be in bootstrap mode where a new system can be downloaded.g) If a communication session is open with the RTU, make sure to use the StopCommunication utility in the Configurator.h) In the Downloader utility, make sure the proper PC COM port is specified in the downloadsession and download the system file using the MMxyyD2.KRL file. The .krl file, whichis found in the C:\MConf150\system directory when the debug system is installed,downloads the corresponding system and kernel files to the RTU.i) Make sure that the CM2 LED is lit, indicating that the port is ready to communicate withthe Microtec debugger.j) Connect Port 2 of the RTU to the PC COM port on which the XRAY debugger runs.k) Copy the include file (e.g. MM_V100.inc) which suits your MOSCAD-M version into thedirectory. Compile and link your source files.l) Use the MCDEBUG.BAT file to load the ‘C’ application into the RAM.m) Follow the debug instructions in the ‘C’ Toolkit for MOSCAD Family RTUs manual.If the unit is powered off or if the main power input falls below 3.1VDC, the RAM data will not be retained and the debugger will have tobe downloaded again.
Appendix B: Models and Accessories44Logic AnalyzerThe MOSCAD-M debug board can be connected to a Logic Analyzer in order to performsophisticated debugging. The Logic Analyzer is used when it is necessary to see what isrunning on the data and address bus. This is generally in extreme cases where the memory iscorrupted and the problem cannot be found using the debugger capabilities.The Logic Analyzer is connected to the board through connectors P12, P13, and P14 on theupper right-hand side of the board. These connectors (Motorola part # 2808044H09) are notprovided with the MOSCAD-M board and must be ordered separately and assembled.The pins of the connection cable should be configured according to the Pin Assignment below.Once the pins are configured, the cables should be connected from the Logic Analyzer to theconnectors on the board.Pin Assignment – Logic Analyzer TBsThe following charts indicate the function of each pin in the various connectors.P12Pin #Function P12Pin #Function1 NC 11 Address bus Add bit 82 NC 12 Address bus Add bit 73 PG0_DTACK 13 Address bus Add bit 64 Address bus Add bit 15 14 Address bus Add bit 55 Address bus Add bit 14 15 Address bus Add bit 46 Address bus Add bit 13 16 Address bus Add bit 37 Address bus Add bit 12 17 Address bus Add bit 28 Address bus Add bit 11 18 Address bus Add bit 19 Address bus Add bit 10 19 PG1_A010 Address bus Add bit 9 20 GND
