Using SIS Commands

The SW2 DP can be remotely set up and controlled via a host computer or other device
(such as a control system) that is attached to the rear panel Remote port. Extron Simple
Instruction Set (SIS) commands are issued from the computer and transmitted to the
SW2 DP via RS-232 (see
USB Port

Host-to-switcher Communications

SIS commands consist of one or more characters per field. No special characters are
required to begin or end a command sequence. Enter these commands on your computer
and send them to the SW2 DP using a communication software program such as Extron
DataViewer. When the switcher determines that a command is valid, it executes the
command and sends a response back to the host computer.
Most responses from the SW2 DP to the host computer end with a carriage return and a
line feed (CR/LF = ]), which signals the end of the response character string. A string is one
or more characters.

Switcher-initiated Messages

When a local event such as an input selection takes place, the switcher responds by
sending a message to the host, indicating what selection was entered. No response is
required from the host.
The following switcher-initiated message is sent when the switcher first powers up under
RS-232 control:
