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.

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.)

Connections

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

Verify that all power and ground connections are made in
accordance with local standards.

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.

7

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

8

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

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.

Installation

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.

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

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.

The MOSCAD-M Unit

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

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). In each page, the LEDs have different functions, as described in
the charts below.

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.)

AO (x1)

The MOSCAD-M Unit

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:

Backup Battery

Below 8.9V DC, the unit enters Low Power Sleep mode. 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.

Function TB6

(AI)
Pin #

Function

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.

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.

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.

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.

The Power Management Feature, which is disabled by default, can
be enabled by the user application.

31

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.

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.)

Power Management

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.

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

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.

Power Management

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).

Port No. Configurator Definition

1 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.

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

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

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.

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.

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.

APPENDIX C: CHANGING THE ANALOG INPUT
MEASUREMENT TYPE

General

This chapter describes changing the units of measurements of the AIs, from current to voltage
and vice versa. 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.

Remove Main Board

Press the two small tabs (A) at the top of the Main board (shown in Figure 25) to release the
top of the Main board. Then press the two small tabs at the bottom of the Main board (B) to
release the bottom of the Main board. Lift the Main board out of the housing.

Removing Main Board from MOSCAD-M RTU

Remove Expansion Board

Press the two small tabs at the top of the Expansion board (A) to release the top of the
Expansion board. (See Figure 26.) Then press the two small tabs at the bottom of the
Expansion board (B) to release the bottom of the Expansion board. Lift the Expansion board
out of the housing.

Place Jumpers

Flip over the Expansion board. Locate the four jumpers marked P7, P8, P9, and P10, near the
center of the board, as shown in Figure 27. All jumpers which are placed measure 4-20mA.

To change an AI to 0-5V, remove the jumpers. Make sure to save the cap. To change an AI to
4-20mA, place the jumpers. Press the cap down until you hear it click.

The chart below shows the correlation of jumpers to AIs.
