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 or the front panel USB port.
Commands can be entered using a Telnet application such as the Extron DataViewer,

protocol cannot be adjusted. This section describes SIS communication and control. Topics

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

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.

Error Responses

When the scaler receives a valid command, it executes the command and sends a
response to the host device. If the unit is unable to execute the command, it returns an error
response tot he host.
