instructions for the installation and operation of the MOSCAD-M ™ Remote Terminal Unit (RTU). It also provides on-site tuning instructions for RTU elements that do not necessarily require shop level assistance. This manual covers the basic RTU and most communications and I/O options. The online help of the MOSCAD-M RTU Configurator contains additional information on the RTU. General Description The RTU is a remotely located unit used for monitoring and control of local equipment. The unit can operate in stand-alone mode, or as an intelligent RTU or node on a distributed control system. The RTU consists of the following components installed in a plastic case: printed circuit board, internal/external radio, and battery housing. This manual describes both basic and expanded I/O models. The MOSCAD-M is a low-power unit that incorporates a variety of power save modes which enable the unit to operate with minimal power consumption. The RTU case is suitable for either wall or DIN rail mounting. Figure 1 provides a general view of the MOSCAD-M RTU. The MOSCAD-M RTU is enclosed in an indoor plastic case and is intended for outdoor base station use. The installer must make sure that the installation meets the requirements of the standard and protects the unit from weather hazards. The antenna must be physically secured at a permanent outdoor location. Figure 1 MOSCAD-M RTU –General View with Case Introduction Hardware Options Line, RS232 and RS485 Communication Interfaces A variety of Line, RS232, and RS485 communication interfaces are available: • RS485 adapter • RS232 multiplexer • Ethernet Interface Unit Radio Communication Interfaces A variety of radios can be attached using internal DPSK or duo-binary modem: • Internal radio UHF High Band • Internal radio UHF Low Band • Variety of external radios (GP140/328, HT750, PRO5150) For details on the available external radio models, and their connection to the RTU, see Appendix B. I/O Configurations Different models of the MOSCAD-M RTU have slightly different I/O configurations. Models with basic I/O configuration: • 12 Digital Input • 8 Digital Output (4 Magnetically Latched, 4 Open Collector) • 2 Digital Output (Solid State) Models with expanded I/O configuration: • 15 Digital Input • 8 Digital Output (4 Magnetically Latched, 4 Open Collector) • 4 Analog Input (4-20 mA) • 1 Analog Output (0-5V or 4-20mA) • 2 Digital Output (Solid State) Power Supply and Battery The power supply and backup battery options are: • 9-30V DC power input (compatible with 12V DC Solar Panel) • 3 x “C” backup battery (for Real Time Clock and RAM retention) INSTALLATION General MOSCAD-M SAFETY SUMMARY The MOSCAD-M should be installed by qualified and authorized technicians. 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 longer cables and/or cabinets are used, the installer is responsible for making sure that the installation complies with the requirements of the relevant standard. The product is a radio accessory. The installer must make sure that the radio connected to the system has all required approvals and that the installation meets the requirements of the standard. This equipment is a base 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 • Miscellaneous Wall Mounting The dimensions of the unit are: width – 21.5 cm (8.46"), height – 18.5 cm (7.28"), depth – .85 cm (.33"), weight – 1.5kg maximum (see Figure 2). Installation Figure 2 Dimensions of MOSCAD-M RTU Plastic Case The unit can be installed on screws or on DIN rail mounting. Before installing the MOSCAD-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 (internal radio models), allow for an extra 10 cm (4"): 2.02 cm (.8") from the top of the box for the RF connector and 8 cm (3.15") for the wires. For models with external radios, allow 8 cm (3.15"). Wall Mounting with Screws The 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 the screws (see Figure 3). The screws used should not protrude from the wall surface by more than 6 mm or by less than 4 mm. Installation Figure 3 Installation of MOSCAD-M – Screw Mount It is also possible to attach the MOSCAD-M to the wall using the small screw hole at the bottom of case, though this requires dismantling the RTU, which is generally discouraged. Consult Motorola service personnel before opening the MOSCAD-M casing. To mount the RTU: 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 than 3.5 mm and head size is at least 5.5 mm. 3. Reassemble the parts of the MOSCAD. Before beginning any disassembly or reassembly procedures, you should be adequately grounded to prevent damage to static sensitive devices in the unit. Wall Mounting on DIN Rail For mounting the RTU on a DIN rail, two universal foot elements (Phoenix Connectors MFC PIN 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 in Figure 4. Press until they click behind the snaps that secure their placement. (See zoomed image in Figure 5.) Installation Figure 4 DIN Rail Attachment SNAP Figure 5 DIN Rail Attachment-Foot Element Snap-in (Enlarged) 2. Press the unit onto the DIN rail, using both universal foot elements. The elements can be used on DIN rail 35 mm and G rails. (See Figure 6). Figure 6 MOSCAD-M Mounted on DIN Rail Installation Connections Verify that all power and ground connections are made in accordance with local standards. Ground Connection Connect the grounding cable directly to the protective grounding pins 9 and 10 (PGND) in the main power-in connector (see TB1 in Figure 9). Power Connections The 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 unit with a 3.5 amp fuse on the cable. Backup Battery Connection The RTU has a special chamber for 3 “C” alkaline backup batteries (not supplied) that are used to retain the unit’s RAM and Real Time Clock in power fail situations. Internal Radio Connection - antenna The internal radio is connected through the 14-pin connector on the Main board inside the plastic housing. Its power is driven from that connector. When an internal radio is installed, Port 3 of the radio cannot be used. External Radio Connection Connect 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 the unit is powered off. Installation If 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 P11 jumper located on the Main board. (See markings on the board.) To set the power to 8V, remove the jumper and save for future use. This is usually set in the factory according to the external power supply of the radio. The default setting is 9V DC. To change the voltage, follow the disassembly instructions in Appendix C, place the jumper and reassemble. Line Communication Connection Line Communications are connected through Ports 1 or 2 (see Figure 9.) Port 1 can be programmed as RS485 (1A) or RS232 (1B). Port 2 can be programmed as RS232. Installation Installation of Backup Batteries The backup battery should not be installed before the unit is connected to the main power supply. This may cause the battery to drain. 1. Place 3 “C” size alkaline batteries into the carton cylinder, each in the same direction, as shown in Figure 7 below. Figure 7 Backup Battery Cylinder and 3 Backup C Batteries 2. Place the cylinder with the batteries into the battery case in the direction indicated on the unit (see Figure 8 below). Figure 8 Installation of Backup Batteries Installation Miscellaneous Open the Case Door To open the case door properly, press the two clips (latches) and pull the wing to an open position. The cable cover is opened counter-clockwise to expose the cable connections and the backup battery cover is opened clockwise to expose the battery housing. Close the Case Door To close the case door properly, press until the latch clicks. Note that if the batteries in the housing are not inserted properly, the backup battery cover door may not close. If the cable connections are not threaded properly through the cable holes, the cable cover may not close. Antenna Placement The antenna is connected to the internal radio through the snap hole on top of the plastic housing (see Figure 9). For models with external radios, screw the antenna onto the radio antenna connector. An antenna placed on top of the plastic housing produces strong electromagnetic fields that could be harmful to the electronics of the MOSCAD-M RTU and to people in the vicinity. Fixed Site Antennas The antenna installation must comply with the following requirements in order to assure optimal performance and make sure human exposure to radio frequency electromagnetic energy 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 manage the site in accordance with applicable regulatory requirements. This may require additional compliance actions such as site survey measurements, signage, and site access restrictions in order to ensure that exposure limits are not exceeded. 10 THE MOSCAD-M UNIT Overview The MOSCAD-M RTU (shown below) contains power connections, line communication ports, internal/external radio interfaces, radio modems and I/Os. Figure 9 MOSCAD-M Unit 11 The MOSCAD-M Unit Communication Ports The MOSCAD-M RTU has 3 ports available: PORT 1 - RS232 Configurator Port (for programming and monitoring the unit), RS232 External Dialup Modem, or RS485 Communication, User protocol (1A is used for RS485) (1B is used for RS232) PORT 2 – Secondary Port RS232 (User protocol) PORT 3 – External Radio interface Ports 2 and 3 can work simultaneously with each other and with either Port 1A or Port 1B. Ports 1A and 1B cannot work simultaneously. Port 3 cannot be used when an internal radio is installed. Connectors The 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) - TB1 DO (10 pin) – TB2 DO/DI (10 pin) – TB3 DI (10 pin) – TB4 DI/AO (10 pin) – TB5 AI (10 pin) - TB6 The 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 Indicators The push-button is used to activate the LED panel, to toggle the LED panel so that it displays the status of the CPU or of the I/Os, to initiate software downloading to the CPU, and to erase User Flash memory and RAM. 12 The MOSCAD-M Unit LED Control Display On/Advance When 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 next page, 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 (Hardware Test Controlled). The next depression of the push-button returns the display to the CPU. Display Off The display can be programmed using the Configurator Site Configuration tool to turn off automatically after a predefined period of time if the push-button has not been pressed. LED Test When the push-button is pressed continuously for a few seconds, all LEDs light up simultaneously. When the push-button is released, the LEDs turn off. User Flash Erase After power-up, all LEDs light up. To erase the User Flash, press the push-button while the LEDs 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 erase the User Flash. User RAM Erase (Cold Restart) Turn off the power supply, while the push-button is depressed. The next time the unit is powered 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 network configuration) will not be erased. System Software Downloading During power up, press the push-button continuously. This will cause the unit to enter bootstrap downloading mode, in which the FLASH is programmed from a PC connected to Port 1 of the MOSCAD-M. The CPU LED will begin to blink at 1 Hz, indicating that the CPU has entered bootstrap downloading mode. If after 120 seconds no bootstrap software is loaded and executed, the normal power-up procedure is performed. CPU Reset To reset the CPU when a backup battery is not installed, turn the power supply to the unit off and on again. When a backup battery is installed, follow the Cold Restart method described above. 13 The MOSCAD-M Unit LED Display Indications A 5 × 4 matrix of LEDs is used for diagnostics and testing of the unit (see Figure 10). The top row indicates to which page or toggle (CPU, IO1, IO2, IO3, Page 4, Page 5, Page 6) the LED panel is set. To advance from one page to another, press the push-button once quickly. The first depression of the push-button activates the display. Subsequent short depressions of the push-button advance the display to the next page: 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 (Hardware Test Controlled).

They are connected to the Power In TB1 (pins 3-8) and can drive up to 400mA each. The switches are equipped with over-current protection, limiting the current driven through each of them to 400 mA maximum. Figure 11 shows how the solid state DOs are to be connected. It is recommended that the wetting power be connected to the solid state output with a fuse of 1 amp. Figure 11 Main Board Solid State Digital Output I/O Connection 22 The MOSCAD-M Unit DO Magnetic Relay connection (x4) Four magnetically latched Digital Outputs are connected to TB2. They can drive up to 2A. Figure 12 shows how the DOs are to be connected. Figure 12 Main Board Magnetically Latched Digital Output I/O Connection DO Open Collector (x4) Four open collector Digital Outputs are connected to TB2/TB3. The DOs can sink a current of up to 500mA. They are divided into two groups of two, each with a common ground. Figure 13 shows how the DOs are to be connected Figure 13 Main Board Open Collector Digital Output I/O Connection 23 The MOSCAD-M Unit DI (x12) Twelve wet Digital Inputs are connected to TB3-TB5. Three of these (DI1-DI3) may be used as Wakeup events for the RTU. DI11-DI12 can be used to count pulses of up to 10KHz. They count the rising edge of the pulse. They can also show the actual state of the DI (On/Off). Figure 14 shows how the DIs are to be connected. Figure 14 Main Board Digital Inputs I/O Connection 24 The MOSCAD-M Unit Additional I/Os (Expanded I/O Models only) AI (x4) Four Analog Inputs are connected via TB6. (See Figure 9.) The AIs are 4-20mA or 0-5V. Each AI has a jumper which determines the measurement. If the jumper is placed (closed), the AI is set up to measure current (4-20mA). If it is not placed (removed), it measures voltage (0-5V). The jumpers are placed in the factory based on customer order. If the status of the jumpers is changed, the AI Type must be changed accordingly in the Hardware Test tool of the MOSCAD-M Configurator. See Configurator help. Four options are available for the AI expansion configuration. The default AI setup of all MOSCAD-M PLUS radios will be 4-20mA (no option is required.) Options AI1 AI2 AI3 AI4 Default 4-20mA 4-20mA 4-20mA 4-20mA V741 4-20mA 4-20mA 4-20mA 0-5V V742 4-20mA 4-20mA 0-5V 0-5V V743 4-20mA 0-5V 0-5V 0-5V V744 0-5V 0-5V 0-5V 0-5V A label on the plastic housing will specify the AI setup. If, for some reason, the jumpers need to be changed, the RTU must be disassembled. For instructions, see Appendix C. Figure 15 shows how the AIs are to be connected. Figure 15 Expansion Board Analog Input (Voltage/Current) I/O Connection 25 The MOSCAD-M Unit AO (x1) One Analog Output is connected to TB5. The AO is 0-20mA or 0-5V. The AO type (current or voltage) is determined by connecting to the proper pin on the TB and by selecting the proper AO type in the software (either via the Configurator Hardware Test utility or the user software application.) The AO can be driven from an internal or external power supply. The minimum output resistance for voltage is 5KΩ. The maximum output resistance for current is as shown below: Power Supply Current Output Maximum Output Resistance Internal 8VDC 120 Ω Internal 6VDC 100 Ω Internal 9VDC 250 Ω External (24VDC) 23-30VDC 750 Ω External (24VDC) 22VDC 700 Ω External (24VDC) 20VDC Max 600 Ω The figure below shows how the AO is to be connected.

As long as the input power is above 6V DC, the unit is still powered from the main power supply input. If the input power drops below 6V DC, the unit will use the backup battery to preserve the contents of the RAM and Real Time Clock (RTC) data. In this case, the unit is in Low Power Sleep mode and not in Reset 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 the backup 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), the unit 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 voltage drops below 3.5V. This indication is also available for the user application. Under these circumstances, the SS1 and SS2 Solid State switches are turned off even if they were set to independent operation mode. 29 The MOSCAD-M Unit Power Supply The MOSCAD-M can be operated from an input of 9-30V DC. The minimum input level is determined by the output voltage level required for the AUX/Internal radio. The table below describes the minimum input levels for the different settings: Output Power Minimum Input Power 6.5 7.5 10 10.5 9.6 11.5 The AUX/Internal radio power is set by a jumper on the Main board. The table below describes the different models with their default settings from the factory: Model Output Power Minimum Input Power F4570A 9.6 11.5 F4571A 10.5 F4572A 10.5 F4573A 7.5 F4574A 7.5 F4575A 7.5 F4580A 9.6 11.5 F4581A 10.5 F4582A 10.5 F4583A 7.5 F4584A 7.5 F4585A 7.5 30 POWER MANAGEMENT Overview The MOSCAD-M includes a Power Management feature which is controlled by the user application. The unit can operate in four power save modes: • Power Management Disabled (in which the entire system is operational and no power saving technique is used) • Run mode (in which the entire system is operational and power is provided only to active ports 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 system tasks are idle, and the Power Management Feature is enabled, the RTU will enter Idle Sleep mode in order to conserve power. The unit will return to Run mode if one of several Wakeup events occurs. If the input power falls below 8.9V, the unit automatically enters Low Power Sleep mode. The unit will return to its previous mode (Run or Idle Sleep) when the input power returns to at least 9.3V. The Power Management Feature, which is disabled by default, can be enabled by the user application. Run Mode In Run mode, tasks will execute, suspend and exit, as necessary. In order to execute, each application and system task will request a ‘visa’ from the ‘visa manager’. When the task suspends or exits, its visa is returned. If all visas in the system have been returned, the unit can enter Idle Sleep mode. A task can choose to operate without a visa; however, it may be forced 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 wake up. When the requested Wakeup event occurs, the task will receive a signal and awaken (even if the Power Management feature is disabled.) If one of these events occurs while the system is 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 @ 14V DC. Typically, power consumption will be 50mA. The additional power consumed by the radio in Run mode depends on the radio type and will be at least 40mA. 31 Power Management Sleep Mode The 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 and devices (communications inputs and outputs, etc). In Sleep mode, the unit’s power consumption will be <5mA @ 14V DC. In Sleep mode, the current consumption is <5mA. However, the power consumption will be significantly higher if the AO is enabled or the radio port is defined as a Wakeup event. If Port 3 is enabled in Sleep mode, the power consumption will be 30mA and the radio power consumption will be at least 40mA, for a total of at least 70mA. 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 supply One or more of these power supplies might be left active, depending on the type of Wakeup events that are selected. (See Wakeup events below.) The AO power supply will not be disabled in Idle Sleep mode if a value is set in the AO. By default, The solid state SS1 and SS2 switches are controlled by the Power Management feature. However, it is possible to configure them to an independent operation mode where they are controlled (enabled/disabled) by the user application only. If the unit enters Low Power Sleep mode, SS1 and SS2 will be turned off even if set to independent operation mode. If one of several preprogrammed Wakeup events occurs, the unit will return from Idle Sleep mode to Run mode. Those tasks which requested the Wakeup event will wake up and any other 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 previous mode. 32 Power Management Wakeup Events When enabling the Power Management feature, the MOSCAD-M user should configure those Wakeup events that will wake up the unit from Idle Sleep mode. The possible Wakeup events are: • DI Wakeup When a Change of State occurs in DI1 and/or DI2 and/or DI3, a Wakeup event is generated. • Push-Button Wakeup Pressing 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 30 seconds. • Communication Port Wakeup A signal received at one of the unit’s three ports, if designated by the user as a Wakeup event, 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) Wakeup The Real Time Clock (RTC) will cause the unit to wake up every 5 minutes to reset the watchdog timer. The user application can request a wakeup after a certain period of time or upon receipt of a specific Wakeup event. This will then cause the system tasks (and the unit) to wake up and the unit to return to Run mode. See the ‘C’ Toolkit for MOSCAD Family RTUs manual (68P02956C75) for details on the system functions which provide these services to the application. For more information on the Power Management Feature, see the MOSCAD-M RTU Configurator User’s Guide (68P02961C55). 33 ETHERNET INTERFACE OPTION Overview The Ethernet interface option is used as a communication link for the MOSCAD-M units with Local Area Networks (LAN). The Ethernet interface option supports TCP/IP protocol on a Twisted Pair (TP) connector, with automatic polarity correction. External Ethernet Interface Unit Enclosed in a plastic box, the external Ethernet Interface unit provides an RS232 port for connection of MOSCAD units to LAN. The external Ethernet unit is powered by 9-15V DC and has indication LEDs on its front panel. The system software of the external Ethernet unit can be upgraded using the Ethernet Interface Downloader program. The following figure depicts the front panel of the Ethernet unit. 12V DC (9-15V) Power inlet Power LED RS232 Connector to RTU RST - Reset DIAG - Diagnostics Data Present Ethernet indication LEDs Ethernet twisted pair connector RS232 indication LEDs Figure 18 External Ethernet Unit – Front Panel The Ethernet indication LEDs are: • TX - Ethernet Transmit • RX - Ethernet Receive • LI - Ethernet Link Integrity The RS232 indication LEDs are: • TX - RS232 Transmit • RX - RS232 Receive • CM - RS232 Channel Monitor 34 Ethernet Interface Option Installation The unit can be connected to Port 1 or Port 2 of the MOSCAD-M RTU. (See Figure 9.) Connections To connect the external Ethernet Interface unit, proceed as follows: 1. Connect the communication cable (FKN5953A) between the external Ethernet Interface unit RS232 Port (P2) and the MOSCAD-M RS232 port (Port 1B or Port 2). If the communication cable is not long enough (80 cm) for external connections, use a longer cable. 2. If no radio is attached to the MOSCAD-M, connect the power cable (FKN4465A) between the Ethernet unit power inlet and the AUX DC connector on the MOSCAD-M. Make sure that the AUX DC is configured to 9V DC and above, as described in the External Radio Connection section of the Installation chapter. If a radio (internal or external) is attached to the MOSCAD-M, connect the Ethernet unit power inlet to an external 9-15V DC power supply using the external power cable FKN4090A (not supplied). 3. Connect the Ethernet Interface unit Ethernet Port (P1) to the LAN, using an Ethernet twisted pair shielded cable. Install a Suppression Core (Fair-Rite) P.N. 0443164151 on the cable as shown below.

The following applications are covered: • RTU-to-Computer/Terminal Connections • RTU-to-Modem Connections • RTU-to-RTU Connections RTU-to-Computer/Terminal Connections For a 25-pin or 9-pin D-type connector, use the FLN6457 cable kit, in order to connect one of the RTU RS232 ports to a computer or terminal. The kit includes a cable with RJ45 modular jacks on both ends, an RJ45 to 25-pin female D-Type adapter, and an RJ45 to 9-pin D-Type adapter. When the connector is facing upwards, the left-hand pin is Pin No. 1, and the right-hand pin is Pin No. 8.

RTU-to-Modem Asynchronous Connection For a 9-pin or 25-pin connection, use the FLN6458 cable kit to connect one of the MOSCAD-M RTU RS232 ports asynchronously to a modem. (The RTU serves as DTE.) The kit includes a cable with RJ45 modular jacks on both ends and an RJ45 to 9-pin and 25-pin male D-Type adapter (see Figure 21). The possible RTU configurations are detailed below: Port No. Configurator Definition RS-232 UART External Dialup Modem (MDLC) 1. Before transmitting, the RTU sends an RTS=on signal to the modem, and will not transmit unless it receives a feedback CTS=on signal from the modem. 2. The RTU will not receive unless it receives a DCD=on signal from the modem. 3. When using a modem in auto-answer mode (connected to a computer port) for remote service, the RTU does not support the RTS/CTS protocol, as the port is designed to operate with a local computer as well as with a modem.

Set the middle knob (channel select knob) to Channel 1. • Use the BNC Adapter to connect an external antenna to the radio. 41 Appendix B: Models and Accessories MOSCAD-M Installation Kit for GP140/GP328/HT750/PRO5150 Radios The MOSCAD-M Installation Kit for GP140/GP328/HT750/PRO5150 Radios enables users to install a GP140, GP328, HT750 or PRO5150 radio (externally) to the MOSCAD-M. The Installation Kit includes: • Mounting Bracket (FCN5516A) • Audio Communication Cable (FKN5953A) • Audio Accessory Adapter (HLN9716B) • DC Power Cable (FKN4465A) • BNC Adapter (HLN9756A) • DIN Rail Radio Connectors (Part #0786144U05) See Figure 23 for connection details. MOSCAD-M Debug Kit The MOSCAD-M Debug kit enables the user to debug a ‘C’ application using the XRAY debugger. Set up the MOSCAD-M Configurator PC as described below, then follow the debugging instructions in the ‘C’ Toolkit for MOSCAD Family RTUs manual. MOSCAD-M Board The kit consists of a special MOSCAD-M board, specifically built for debugging. The system software (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-M Configurator 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 pushbutton there are two additional buttons which do not exist in the standard MOSCAD-M. The leftmost button is Reset. The rightmost button is NMI (Non Masked Interrupt). The NMI (or CTRL+C from the PC keyboard) will stop the program. Two megabytes of RAM are installed in the debug board to enable downloading the system software from the PC to the unit. 42 Appendix B: Models and Accessories Debug Setup By default, downloading from the PC to the unit is done via Port 2. When the unit is first powered up, LED 12 (CM2) should be lit, indicating that the debugger should be downloaded via Port 2. In order to connect to Port 1, a modified system file must be downloaded to the flash. This file is 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 standard MOSCAD-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 system will 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 Stop Communication utility in the Configurator. h) In the Downloader utility, make sure the proper PC COM port is specified in the download session and download the system file using the MMxyyD2.KRL file. The .krl file, which is 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 with the 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 the directory. 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 3.1V DC, the RAM data will not be retained and the debugger will have to be downloaded again. 43 Appendix B: Models and Accessories Logic Analyzer The MOSCAD-M debug board can be connected to a Logic Analyzer in order to perform sophisticated debugging. The Logic Analyzer is used when it is necessary to see what is running on the data and address bus. This is generally in extreme cases where the memory is corrupted 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 the upper right-hand side of the board. These connectors (Motorola part # 2808044H09) are not provided 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 the connectors on the board.

To do so, the RTU is disassembled, jumpers are placed on the Expansion board, and the unit is reassembled, as described below. The AI setup of the MOSCAD-M PLUS radios is described under AI (x4) in the Installation chapter. If the status of the jumpers is changed, the AI Type must be changed accordingly in the Hardware Test tool of the MOSCAD-M Configurator. See Configurator help. Before beginning any disassembly or reassembly procedures, you should be adequately grounded to prevent damage to static sensitive devices in the unit. Disassembling the RTU Remove Connectors Before opening the RTU, the five 10-pin connectors on the bottom of the RTU must be disconnected. Note the configuration of the connections so that they can be easily reconnected after placing the jumpers and reassembling the RTU. Open RTU Turn the unit upside down, so that the rightmost wing is closer to you. Using both thumbs, press the two tabs (A) at the bottom of the unit, as shown in Figure 24, to release the back of the case. Lift the cover (B) and push forward slightly (C), to release the cover from the top tabs.
