Appendix B: Remote Control

This appendix describes how to remotely control the television
demodulator. This appendix provides the following information:

Serial port connection

Programming model

Command syntax descriptions

Alphabetical list of commands

Serial Port Connection

CAUTION.

 Connecting or disconnecting cables while the television

demodulator is powered on can result in damage to its input circuits.

The rear panel SERIAL connector allows remote control of the
television demodulator using a PC controller. The connector is a 9-pin,
subminiature D-type with female contacts. Table B–1 and Figure B–1
give the pin configuration for the SERIAL connector.

The SERIAL connector provides a configurable serial communica-
tions port. You can configure the serial port as either RS232 or RS485
using the Serial Configuration menu. Refer to page 3–8.
