3.9 Selection of Intelligent Transceiver Unit (ITU) Location
After the mounting locations for the FM/DHF and GPS antennas have been determined, a
suitable location for the ITU must be determined. As the FM/DHF and GPS antennas have a
fixed length of cable, the location of the ITU will be determined by the proximity of the cable
ends. Similar to the FM/DHF and GPS antennas, the location of the ITU needs to be
considered as this unit also has a fixed non-adjustable length cable.
Note: Cable routing usually takes more wire length than expected.
Preferred ITU locations within the cab are behind the driver or passenger seat, in a storage
compartment, in the living area, or under the bunk. For day cab tractors, install the ITU on
the rear bulkhead, or under the seat.
CAUTION ! Air ride seats have a wide range of motion; ITUs and DTs mounted
within the range of motion of air ride seats can cause damage, both to the seat and
to the Terion equipment. If you are planning to mount the ITU or DT near an air
ride seat, check the seat’s full range of motion – forward, back, up and down.
