SIS Communication
and Control
The DVS 605 can be configured and controlled via a host computer or other device (such as a control system) attached to the rear panel
Commands can be entered using a Telnet application such as the Extron DataViewer, available at www.extron.com. See the DataViewer Help file for use.
This section describes SIS communication and control. Topics that are covered include:
•Host to Scaler Communications
•Commands and Responses
The scaler uses a protocol of 9600 baud, 1 stop bit, no parity, and no flow control and the rear panel
Tx Rx G G IR
Host to Scaler Communications
SIS commands consist of one or more characters per field. No special characters are required to begin or end a command sequence. When the DVS 605 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 DVS 605 scaler responds by sending a message to the host. No response is required from the host. Example
