TCU Installation Terrestrial Mobile Communications Terminal Installation Instructions
14 QUALCOMM Proprietary 80-53184-1 Rev. A
Location and Orientation
• Choose a location where the unit will not come into contact with liquids or solvents.
• Choose a location where tire chains or other tools will not likely be stowed on top of the unit or
cables. Do not mount the unit near items that may fall on it or bump cable connections.
• Choose a location that is structurally sound. The surface must support the full weight of the TCU
(total weight for TCU is approximately 2 lbs.) under all circumstances.
• Install the TCU so that the connector panel is facing down towards the floor. This will protect cable
connections from accidental damage and will discourage tampering. Be sure to provide enough
room for cable bends or the removal of cables for servicing (4” to 6” is recommended).
• Install the TCU so that the unit, cables, and any accessories can be serviced in the future.
Installing the TCU
To install the TCU follow these steps:
1.
Mark the exact TCU installation location (usually on the cab wall behind the driver’s seat about
two feet from the floor).
2.
Mount the TCU into proper position (with cable connectors facing down) and drill holes in the
appropriate spots.
3.
Secure the TCU in place using the supplied self-drilling mounting hardware.
4.
Connect all the cables to the appropriate TCU connectors.
Connecting Cables to the TCU
Inspect all cables for bent pins or other damage before connecting them to the TCU.
The TCU should be oriented so that the connector panel is facing away from accessible areas. This will
protect the cables from accidental damage and will discourage tampering.
Connecting the Antennae Connector to the TCU
Plug the GPS/PCS Antenna connector into the appropriate slot. Tighten the screwlocks on the
connector securely.
Connecting the EDU Connector to the TCU
Plug the EDU Cable connector into the appropriate slot. Tighten the screwlocks on the connector
securely.
Connecting the Handset Connector to the TCU
Plug the Handset Cable connector into the appropriate slot. Tighten the screwlocks on the connector
securely.
