IN1606 Scaling Presentation Switcher • SIS Communication and Control 25
SIS Communication
and Control
The IN1606 can be configured and controlled via a host computer or other device (such
as a control system) attached to the rear panel RS-232 connector, the LAN port or the
front panel USB port. Control is accomplished using the Extron Simple Instruction Set (SIS)
commands or the IN1606 internal Web pages.
Commands can be entered using a Telnet application such as the Extron DataViewer,
available at www.extron.com (see the DataViewer Help file for more details).
This section describes SIS communication and control. Topics in this section include:
• Host and Scaler Communication
• SIS Overview
• Command and Response Tables
The scaler uses a protocol of 9600 baud, 1 stop bit, no parity, and no flow control (see
RS-232 Connector on page 9).
Host and Scaler Communication
SIS commands consist of one or more characters per field. No special characters are
required to begin or end a command sequence. When the IN1606 determines that a
command is valid, it executes the command and sends a response to the host device. All
responses from the scaler to the host end with a carriage return and a line feed
(CR/LF = ]), indicating the end of the response character string (one or more characters).
Scaler-Initiated Messages
When a local event such as a front panel selection or adjustment takes place, the IN1606
scaler responds by sending a message to the host. No response is required from the host.
Example scaler-initiated messages are listed here.
• In X! All ] (where X! is the input number during an input switch).
• Reconfig ] The IN1606 sends this response when an input is switched or when a
new signal is detected.
