4.5.3.1 Required Control Cabling (Regardless of Driving Traffic Data Type)
For RMI connections:
The Control/Data Cable CA/WR0066 (DB-25F to DB-25M, 6’) provides
the serial communication path between the Redundant CDM-625 and the CRS-300 (via the
CRS-310 RMI) for all driving traffic data types, and is therefore always required.
For all driving traffic data types
, refer to Figure 4-10 through Figure 4-12 to connect and
secure the CA/WR0066 cable between the Redundant CDM-625 and the CRS-310 RMI on the
CRS-300 as follows:
• DB-25F connector labeled “Data Interface” on Redundant CDM-625, to
• DB-25M connector labeled “P1” on the CRS-310 RMI.
For TMI connections:
Depending on the driving data traffic type, in addition to its use as a
control cable between the Redundant CDM-625 and the CRS-310 RMI, the CA/WR0066 cable is
used as a control cable between the Traffic CDM-625(s) and the CRS-330 or CRS-340 TMI; as a
data cable with the CRS-316 TMI; and as a combination control/data cable when used with the
CRS-340 TMI.
