RS-232 Links

The switcher has three 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:
• Two (Primary and Secondary) rear panel RS-232 ports on 3-pin captive screw
• The front panel Confi guration (RS-232) port, a 2.5 mm mini stereo jack
The default protocol for all ports is as follows:
• 9600 baud
• 1 stop bit
The RS-232 ports can be confi gured to operate at the 9600, 19200, 38400, or 115200
baud rate.
N These three ports are hardwired for RS-232 only.

The rear panel RS-232 Secondary port is active only if the front panel
Confi guration port is not in use. If a front panel confi guration connection is
made, the rear panel RS-232 Secondary port becomes inactive and the front panel
Confi guration port is active.
The switcher can operate at 9600, 19200, 38400, or 115200 baud rates, but
Extron recommends leaving these ports at 9600 baud only.
See Selecting the RS-232 Primary port's baud rate in chapter 3, Operation,
to confi gure the RS-232 Primary port from the front panel.
See the Set serial port parameters command on page 4-18 to confi gure all of
the ports using an SIS command.
