Using Simple Instruction Set (SIS) Commands
The SW DVI Plus 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/Auto-SW port. Extron
Simple Instruction Set (SIS) commands are issued from the computer and transmitted to the
SW DVI Plus via RS-232. (See
information on connecting to this 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 SW DVI Plus using a communication software program such as Extron
DataViewer or HyperTerminal. 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 SW DVI Plus 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 a front panel 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:
