RS-232 Ports
The switcher has three serial ports that make serial control of the switcher possible. The
ports can be connected to a host device such as a computer running the DataViewer utility,
an RS-232 capable PDA, or a control system. The serial ports are:
z
z
Two (Primary and Secondary) rear panel RS-232 ports on 3-pin captive screw connectors
z
z
The front panel Configuration (RS-232) port, a 2.5 mm mini stereo jack
The default protocol for all ports is as follows:
z
z
9600 baud
z
no parity
z
8 data bits
z
z
1 stop bit
z
no flow control
Besides the default 9600 baud, the RS-232 ports can be configured to operate at the 19200,
38400, or 115200 baud rate.
NOTES:
•
These three ports are hardwired for RS-232 only.
• The rear panel RS-232 Secondary port is active only if the front panel
Configuration port is not in use. If a front panel configuration connection is
made, the rear panel RS-232 Secondary port becomes inactive and the front
panel Configuration 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 “
the Baud Rate of the RS-232 Primary Port
configure the RS-232 Primary port from the front panel. See the
SIS command on page 73 to configure all of the ports.
