There are four Remote Control Panel (RCP) Panel Port Connectors, located on the rear of the unit and
illustrated in Figure 3-16. These connectors interface the 864XR frame with external remote system
control panels via an RS-485 compliant serial communication interface using the PESA proprietary
RCP Protocol defined by PESA Document No. 81-9062-0300-0. External remote control panels can
be daisy-chained between one another and the 864XR frame. Any, or all, of the four connectors may
be used to form up to four separate system control branches.

Figure 3-16 - RCP Panel Port Connectors
PESA Remote Control Panels are connected to the RCP Port Connectors in a daisy-chain fashion
using cables constructed with RCP connectors (PESA Part No. 81-9029-0780-0) and shielded,
twisted-pair cable (PESA Part No. 81-9028-0043-2, Belden 8451, or equivalent) as shown in Figure
3-17. The connector body has an integral strain relief requiring the use of a nylon cable tie, included
with the connector. If additional cable ties are required, use PESA Part No. 81-9021-0028-8.
