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.
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.
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.
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).
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).
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.
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).
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.

The MOSCAD-M Unit I/Os (All Models) Wetting switch connection (x2) Two solid state (SS1, SS2) Digital Outputs are provided for wetting/supply voltage control of the DI, AI, or external devices. 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.
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.
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.
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.
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 MOSCAD-M Unit DI (x3) An additional 3 wet Digital Inputs are connected via TB5. Figure 17 shows how the DIs are to be connected.

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 9 6.5 9 7.5 9 8 10 9 10.5 9.6 11.5 The AUX/Internal radio power is set by a jumper on the Main board.
POWER MANAGEMENT Overview The MOSCAD-M includes a Power Management feature which is controlled by the user application.
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.
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.
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.
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.
