Using Simple Instruction Set (SIS) Commands
The SW HDMI LC can be remotely set up and controlled via a host computer or other
device (such as a control system), attached to the rear panel Remote/Auto-SW port, using
the Extron Simple Instruction Set (SIS) commands. See “
Enabling Auto Switching ” in
“Installation” section for 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. You can enter these commands from
your computer using a communication software program such as HyperTerminal. When
the switcher determines that a command is valid, it executes the command and sends a
response to the host device.
Most responses from the SW HDMI LC 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 displayed:
(C) Copyright 2010, Extron Electronics HDMI LC Series, Vx.xx,
60-xxxx-01
The switcher sends the copyright message when it first powers on. Vx.xx is the firmware
version number; 60-xxxx-01 is the part number.
NOTE: This message is displayed only at power-up.
