This section describes the operation of the FOX matrix switchers using the Simple
Instruction Set, including:

• Using the Command and Response Tables
• Special Characters
Host Control Ports
The switcher has one or two (depending on the model) serial ports, and an Ethernet LAN
port. The FOX Matrix 320x has a USB port. Any of these ports can be connected to a host
device such as a computer running the Extron DataViewer utility or the HyperTerminal utility
or a control system. These ports make control of the switcher possible.
Serial Ports
The serial ports are:
• Rear panel Remote port — A 9-pin D connector for serial RS-232 or RS-422 control
(see Remote Port and item
c
on page 13).
• Front panel Configuration port (FOX Matrix 14400 only) — A 2.5 mm mini stereo
jack for serial RS-232 control (see Front Panel Features and item
a
on page 16).
The default protocol for both ports is as follows:
• 9600 baud • no parity • 8 data bits
• 1 stop bit • no flow control
The ports can be configured to operate at the 9600, 19200, 38400, or 115200 baud rate.
NOTES:
• These two ports are independent of one another. A front panel Configuration port
connection and a rear panel Remote port connection can both be active at the
same time.
• The switcher can operate at 9600, 19200, 38400, or 115200 baud rates, but
Extron recommends leaving these ports at 9600 baud only.
• The protocol of these ports can be changed via an SIS command only. See the Set
serial ports parameters SIS command on page 34 to configure these ports using
an SIS command.
