GPS
The 304-SD can be outfitted with an optional GPS module. For optimum results it is recommended that the GPS module be
exterior mounted utilizing the magnetic base with the cable protected by a suitable grommet.
If it is not possible/practical to have the GPS module exterior mounted, the GPS module must be mounted internally with a
direct line of sight vertically skyward.
Inertia, G, Sensor.
The Inertia, G, sensor can detect acceleration of the vehicle. The Inertia sensor can monitor driver behavior: Acceleration;
deceleration and abrupt stopping. The Inertia sensor can detect X/Y/Z axis. The Inertia sensor cable connects to
CAB000323 which has two bundles of 485 wires. Always connect the G-Sensor to the 485-4 of CAB000323. The G-Sensor
connection should always be orientated towards the rear of the vehicle.
Please Note: Only mount the G-Sensor Horizontally on the vehicle floor, if not, inaccurate and/or inconsistent data may occur.

GND connects to Black GND on cable set 485-4 on CAB000323
B.
Green, 485B, connects to Blue/White on cable set 485-4 on CAB000323
C.
White, 485A, connects to Blue on cable set 485-4 on CAB000323

Red connects to Red +5V on cable set 485-4 on CAB000323
Figure 8: Inertia, G- Sensor Wiring.
If the 304-SD has an Inertia, G, Sensor this can be setup
with independent values for X, Y and Z axis, these can be
set to the requirements of the individual customer. The
Inertia sensor can be tested by accessing the Check
Button, System
Sensor
Acceleration. With the
Inertia sensor in your hand click on the Check button (B)
as you quickly move the sensor from left to right. As the
sensor is moved the values of X, Y and Z (C) will change.
After the Inertia sensor has been installed ensure it is
enabled by selecting ON from the Drop down menu (A).
Once selected click the SAVE button.
