This section describes the operation of the MPX 866 A switcher using the Simple Instruction Set, including:

zzRS-232 Ports

zzEthernet (LAN) Port

zzHost-to-Switcher Instructions zz Switcher-Initiated Messages zz Switcher Error Responses

zz Using the Command and Response Tables zz Special Characters

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:

zzTwo (Primary and Secondary) rear panel RS-232 ports on 3-pin captive screw connectors zz The front panel Configuration (RS-232) port, a 2.5 mm mini stereo jack

The default protocol for all ports is as follows:

zz 9600 baud

z

no parity

z 8 data bits

zz 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 “Selecting the Baud Rate of the RS-232 Primary Port” in the Operation section to configure the RS-232 Primary port from the front panel. See the Set Serial Port Parameters SIS command on page 73 to configure all of the ports.
