Serial Ports

Programmer’s Guide

The switcher's BME 0 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/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 data bits
•	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.

NSerial ports on BMEs other than BME 0 should not be used.

Rear panel Remote port

NThe rear panel Remote RS-232/RS-422 port can be configured from the front panel or using Simple Instruction Set (SIS) commands. See "Selecting the rear panel Remote port protocol and baud rate" in chapter 3, "Operation", to configure the port from the front panel. See the "Command/Response table for IP-Specific SIS commands", on page 4-23, to configure the port using an SIS command.
