Introduction to SIS
The switcher can be set up and controlled remotely via Extron SIS commands that are
issued from a host computer running the Extron DataViewer utility or other control system.
The host device can be connected to the USB mini-B config port on the front panel or the
RS-232 port on the rear panel.
NOTE: The wiring in the RS-232 cables crosses over so that the unit transmit (Tx) wire
Host-to-Switcher Communications
SIS commands consist of strings (one or more characters per command field). No special
characters are required to begin or end a command sequence. Unless otherwise stated,
upper and lower case characters can be used interchangeably. Most responses from the
switcher end with a carriage return and a line feed (CR/LF = ]), which signals the end
of the response character string. When the device determines that a command is valid, it
executes the command and sends a response to the host device.
Switcher-Initiated Messages
When a local event such as a change in signal status takes place, the switcher responds by
sending a message to the host, indicating the status change. No response is required from
the host.
