SIS™ Programming and Control

RS-232 Ports

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 connectors

•the front panel Configuration (RS-232) port, a 2.5 mm mini stereo jack

The default protocol for all ports is as follows:

•

9600 baud

•

no parity

• 8 data bits

•

1 stop bit

•

no flow control

 

The RS-232 ports can be configured to operate at the 9600, 19200, 38400, or 115200 baud rate.

NThese 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.

NThe 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 configure the RS-232 Primary port from the front panel.

See the “Set serial port parameters” command on page 4-20 to configure all of the ports using an SIS command.
