Programmer’s Guide

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 Configuration (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 flow control

The ports can be configured to operate at the 9600, 19200, 38400, or 115200 baud rate.

NThese 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.

NThe switcher can operate at 9600, 19200, 38400, or 115200 baud rates, but Extron recommends leaving these ports at 9600 baud only.

NThe 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.
