Serial Ports
The switcher has two serial ports that can be connected to a host device such as a
computer running the HyperTerminal utility, an RS-232 capable PDA, or a control
system. These ports make serial control of the switcher possible. The serial ports
are:
• The rear panel Remote (RS-232 or RS-422) port, a 9-pin D female connector
(figure 3-1)
• The front panel Configuration (RS-232) port, a 2.5 mm mini stereo jack
(figure 3-2)
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.
N 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.
