CAUTION
To avoid potential problems, existing wiring
harnesses must be carefully examined for
evidence of damage, corrosion, or broken
wire strands.
Any damage detected must be repaired
before a new MTX5000 system is placed
into service.
Note
The MTX5000 IDU is available with either the RFU
1 or with both RFU 1 and RFU 2 rear connectors.
If you have only one ODU, disregard connections
and references to the second ODU (RFU 2).
If your MTX5000 IDU and ODU contains the Type “N” connector
RFU 1 and RFU 2 option, the IDU and ODU can be connected
using an existing wiring harness after inspection, subject to the
limits called out in “Cabling Requirements” on page 6-9.
ODU Connections The existing connector(s) at the ODU end of
the wiring harness will connect directly to your MTX5000
ODU(s). Verify that all connections have been completed, as
shown in Figure 6-6 on page 6-12.
IDU Connections At the IDU end of the wiring harness, verify
the connections are as shown in Figure 6-6 on page 6-12.
Connections for ODU 2 (RFU 2) are identical to those for ODU 1
(RFU 1).
The ITT Cannon KPT06F14-12SX connector is utilized on
MTX5000 IDU/ODU configurations that contain the Type “N”
RFU 1 and RFU 2 connector option.
