industrystandardprotocols.Itis availablewith either an 8088 or

80386SX processor.

Power Requirements

12 to 24 volts DC.

Peripherals Supported

The SMG supports:

•Industry standard ruggedized printers

•Integrated GPS receivers

•Industrial PC keyboards

•Point-to-point 2.4 GHz LAN spread spectrum

•Integrated Wireless Wide Area Network radio

modems.

Inactivity Monitor

Shuts down the SMG when the vehicle has been turned off for a

8. Mounting nuts, bolts, and lock washers

9. Wire for power cable - UL listed #18 gauge, stranded,

outside jacket resistant to automotive chemicals with a

nominal outside diameter of .250 in.

Note:

A shielded power cable, terminated to chassis ground is

recommended.

10. Application speciﬁc connectors.

To Install:

1. Select a mounting location that is ﬂat and provides

adequate support and ventilation for the SMG.

Note:

SMG chassis must be grounded to the vehicle chassis.

2. Secure the SMG with appropriate nuts and bolts. Self-

locking nuts or lock washers must be used.

3. Construct the power cable.

•CrimpAMPpins onto wireends usingAMPtoolA9999

or equivalent.

•Slide cable clamp over wire and insert crimp pins into

circular connector housing as indicated

Figure 1

below.

4. Route the power cable to the battery power source.

•Connect the V+ wire to the battery power source,

splicing a fuse holder with an 8 amp fuse in-line with

the power source.

Note:

Locate the fuse as close as possible to the battery power

source.

•Connect the Vehicle Accessory Power to the vehicle

accessory bus, splicing a fuseholder with a 1 amp

fuse in-line with the accessory power source.

Note:

Locate the fuse as close as possible to the accessory power

source.

The accessory bus is the ‘switched’ power source con-

trolled by the ignition key. Connect the power cable to

the power source using appropriate connectors.

•Place a CAUTION label on each fuse holder.

5. Plug the circular connector into the +12/24 VDC connec-

tor on the SMG.

Application Notes

Inactivity Monitor

The inactivity monitor is designed to do an orderly shutdown of

the SMG when the vehicle has been turned off for a period of

time. Two versions are available: a custom hardware

implementation and a generic implementation that is an

application that runs on the SMG.

Hardware Implementation

The SMG monitors vehicle activity via the accessory power bus and

assumes that when the bus is at ground potential, the vehicle has

been powered off. When power to the accessory bus is removed, a

hardware time in the SMG is activated. This causes the SMG to

power down within 3 to 5 minutes. When power is applied to the

vehicle accessory bus (i.e. vehicle power is turned on), the SMG

powers up and goes through the normal boot cycle. If power is ap-

plied to the accessory bus prior to the SMG being deactivated, the

hardware time is halted and reset.

Software Implementation

Application software running on the SMG controls the activity

monitor function. The status of the accessory bus is periodically

monitored and when loss of accessory power is detected, the

software intelligently determines when to shut down the SMG.

The application continues to monitor the accessory bus during

shutdown and halts and resets the timer if accessory power is re-

applied before the shutdown is complete. As with the hardware

implementation, application of accessory power will initiate a

power-up sequence on the SMG.

Note:

Neither implementation can be altered by the vehicle

operator.
