Serial Ports
The switchers have 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
•ThefrontpanelConguration(RS-232)port,a2.5mmministereojack
The default protocol for both ports is as follows:
•9600baud • noparity • 8-bit
•1stopbit • noowcontrol
Theportscanbeconguredtooperateatthe9600,19200,38400,or115200baud
rate.

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 rear panel Remote port can support either RS-232 or RS-422 serial
communication protocol, and can operate at 9600, 19200, 38400, or 115200
baud rates. See “Selecting the rear panel Remote port protocol and baud rate” in
chapter 3, “Operation”, to configure the rear panel Remote port from the front
panel.
