Remote Control
This section describes the remote control operation of the FOXBOX SR HDMI, including:
• Simple Instruction Set Control
• Signal Processing Product Control Program
The receiver has two serial ports: the front panel Configuration port, a 2.5 mm mini stereo
jack (see “
Front panel Configuration Port “ on page 11); and a rear panel Remote
RS-232 port, a 3-pole captive screw connector (see “ RS-232 connections “ on page 8).
Either of these ports can be connected to a host device such as a computer running the
HyperTerminal or DataViewer utility, or a control system to make serial control of the
receiver possible.
The protocol for all ports is as follows:
• 9600 baud • no parity • 8 data bits
• 1 stop bit • no flow control
Simple Instruction Set Control
Host-to-Unit Instructions
SIS commands consist of one or more characters per field. No special characters are
required to begin or end a command character sequence. When a command is valid, the
unit executes the command and sends a response to the host device. All responses from
the unit to the host end with a carriage return and a line feed (CR/LF = ]), which signals
the end of the response character string. A string is one or more characters.
