5.6.1 CRS-170A  CDM-840 Control and IF Interface Connections Using
Cabling Kit KT-0000160
You must order terrestrial data interface components/kits separately. See Section 5.6.2 for
CDM-840 terrestrial data interface configuration and connection examples and details.
You must use Comtech EF Data's KT-0000160 1:1 Redundancy Control/IF Interface Cabling Kit (Section
5.2.1) for your control and L-Band Unit-to-Switch cabling connections. Figure 5-28 and Figure 5-29 show
how to connect a pair of CDM-840s together with the CRS-170A L-Band 1:1 Redundancy Switch module.
The table included with each figure lists the items you will need from this kit for your initial setup.
IMPORTANT: It is ESSENTIAL that you make the Control and the IF Rx and Tx connections
correctly. See Section 5.6.1.1 for details about the CDM-840 Unit-to-Switch Control
Interface connection, and Section 5.6.1.2 for details about the CDM-840 Unit-to-Switch IF
Interface connections.
