6 Intelligent Transceiver Unit (ITU) Installation
1. Determine the best location for the ITU. It should be mounted such that the ITU
cable attachment panel is located away from the driver. The ITU must also be within
reach of the FM/DHF and GPS antenna cables and power cables.
CAUTION! The ITU must be orientated so that the cables attach away
from driver access. This will prevent cables from becoming entangled with
other equipment.
DT can mount to
back of ITU base
plate if space permits
Use ITU base plate
as guide to mark
holes in tractor.
ITU base plate attach
to tractor floor with
¼" – 20 x 1.25” self-
drilling lag bolt.
Cable end of ITU is
mounted to end of
ITU base plate with
wide holes.
2. Install the ITU base plate. Use the ITU base plate as a guide to mark the holes. The
1/4" - 20 x 1.25" lag bolts are self-drilling, but will self-drill much faster if a 1/8"
pilot hole is drilled first.
3. Attach the ITU to the base plate. Mount the ITU to the ITU base plate using four
1/4" - 20 x 3/4" cap screws, flat washers, and star washers.
CAUTION! Do not over-tighten. Excessive torque will damage the ITU
case. Tighten only enough to secure the ITU to the base plate.
4. Attach cables. Plug the FM/DHF, GPS and data cables into the ITU. Wait until you
are ready to calibrate the ITU before plugging the power cable into the ITU.
