Remote controls and status information are transferred via an EIA-485 or EIA-232 serial
communications link menu selection.
Commands and data are transferred on the remote control communications link as US ASCII-
encoded character strings.
The remote control port baud rates can be selected from 110 to 19200 kbps.

The remote communications link is operated in a half-duplex mode.

transmits data on the link unless it is commanded to do so.

configuration change.
