FIGURE 79: RCP Panel Port Connectors
These RCPs are connected to PESA Remote Control Panels with daisy-chained cables constructed
with RCP connectors (Part No. 81-9029-0780-0) and shielded, twisted-pair cable (Part No. 81-9028-
0043-2, Belden 8451, or equivalent) as illustrated in Figure 80. The connector body has an integral
strain relief, which requires the use of a nylon cable tie, which is included with the connector. If this
cable tie is not available, use PESA Part No. 81-9021-0028-8.
