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