Remote Interface
4.4.1 Host Computer Remote Communications
The RCS20 has a dedicated RS-485 serial control port (Remote Port) for use with computer controlled
remote monitor and control systems. The Remote Port is a 9-Pin female 'D' sub connector J3 located at
the rear of the unit on the Switch Interface plug in module. The pinouts for the remote port are listed in
Section 5.
The Remote Port utilizes a binary protocol called Radyne Link Level Protocol (RLLP). RLLP is a multi-
drop packet-oriented protocol with handshaking, and is completely described in Appendix A. The remote
port supports standard UART asynchronous protocol with 8 data bits, no parity, and 1 stop bit (8N1) at 8
baud rates: 115200, 57600, 38400, 19200, 9600, 4800, 2400, and 1200.
REMOTE PORT TEST
Remote test will send ASCII characters 'Test' to remote port
each time the softkey labeled 'Test' is pressed.
