ORBCOMM controller (3, Figure 32-12) transmits
data through antenna (1, Figure 32-13) mounted on
top of the cab. The antenna coaxial cable is routed
through the inside of the cab to protect it from
damage. If the antenna or coaxial cable is damaged,
replace the parts.

Interface Module
Interface module (5, Figure 32-12) receives data
from the sensors installed on the truck and sends this
information to the KOMTRAX Plus controller. There
is a small green LED light on the face of the
controller. With the key switch ON, the light must be
blinking. If the light is continuously illuminated, there
is a problem in the controller.
When a new interface module controller is installed
on the truck, new software has to be installed inside
the controller. IM-Diag connector (1, Figure 32-14) is
used to connect the interface module to a laptop PC
for installing software.
