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.

9
Programmer Notes
The status of the accessory power bus is available to the
application at port 379H bit 7. The application software can
periodically monitor this input and when loss of accessory
power is detected, it can intelligently determine (based on
customer criteria) if and when to shut down the SMG.
The actual power down sequence for the SMG is initiated by the
application setting port 37AH bit 3 to logic 1. This starts the
hardware timer, which shuts down the SMG in 3 to 5 minutes.
Note: The only way to halt and reset the timer is for the
application to clear this bit. To do this, the application
must continue to monitor the accessory power bus in
the event power is re-applied before time-out.
Once the SMG has been shut down, power re-applied to the
accessory power bus initiates a power-up cycle sequence and
the SMG goes through a normal boot cycle.

Regulatory Information
Radio Frequency Interference Requirements
This device must operate in compliance with Federal Communications
Commission (FCC) Rules and Regulations Part 15.
This equipment has been tested and found to comply with the limits for Class A
digital device, pursuant to Part 15 of the FCC rules. These limits are designed to
provide reasonable protection against harmful interference when the equipment is

radiate radio frequency energy and, if not installed and used in accordance with
the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his
own expense.
However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more of the
following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
