IN1606 and IN1608 Series Scaling Presentation Switcher • SIS Configuration and Control 41
SIS Configuration and
Control
The scaler can be configured and controlled with Extron Simple Instruction Set (SIS)
commands when connected to a host computer or other device (such as a control system).
Attach the host device to the rear panel RS-232 connector, the LAN port, or the front
panel USB port. 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 18).
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 scaler 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 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 scaler sends this response when an input is switched or when a new
signal is detected.
• HplgOX@] The scaler sends this response when a hot plug event on output X@ is
detected.
