Introduction to SIS
The distribution amplifiers 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 RJ-45 LAN connector on the rear panel, the 3-pole
captive screw connector on the rear panel, or to the mini USB config port on the front panel.
The serial protocol is 9600 baud, 8 data bit, 1 stop bit, and no parity.
NOTE: The wiring in the RS-232 cables crosses over so that the distribution amplifier
transmit (Tx) wire connects with the control device receive (Rx) and vice versa.
Host-to-Distribution Amplifier 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 distribution
amplifier ends with a carriage return and a line feed (CR/LF = ]), which signals the end of the
response character string. When the switcher determines that a command is valid, it executes
the command and sends a response to the host device.
Distribution Amplifier-initiated Messages
When a local event such as a change in signal status takes place, the distribution amplifier
responds by sending a message to the host, indicating the status change. No response is
required from the host.
