3.7.3Routing the ODU/IDU Interconnect Cable

1. Select where the cable will enter the truck or building from outside.

2. Determine the length of cable required. Allow three extra feet on each end to allow

for strain relief, as well as any bends and turns.

3. Route the cable.

The SDIDU

is equipped with TNC female connector on the rear of the chassis.

Depending on the ODU type, it will be equipped with either an N-type or TNC female

connector at its interconnecting port. A length of coaxial cable (such as Times Microwave

Systems LMR-400, LMR-300 or LMR-200) fitted with the appropriate N-type or TNC male

connectors is required to connect the ODU to the SDIDU

. This cable assembly may be

supplied in fixed lengths with the digital radio. Bulk coaxial cable of equivalent

specification may also be used, with terminating connectors applied during cable

installation.

Based on an evaluation of the cable routing path, pull the ODU/SDIDU

Interconnect

cable from one unit to the other, utilizing cable trays, ducts, or conduit as required. Take

care that the ODU/ SDIDU

Interconnect cable is not kinked or damaged in any way

during installation. Be sure to protect the TNC connectors from stress, damage and

contamination during installation (do not pull the cable by the connectors). If multiple

ODU/ SDIDU

Interconnect cables are to be installed along the same route, the cables

should all be pulled at one time. Be sure the installed cable does not have any bends that

exceed the specified cable bend radius. The ODU/ SDIDU

Interconnect cable should be

adequately supported on horizontal runs and should be restrained by hangers or ties on
