Host-to-Scaler Communications

SIS Communication

and Control

The DSC 301 HD 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 or the front panel USB port. Control is made using the Extron Simple Instruction Set (SIS) of commands.

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	REMOTE

control and the rear panel remote port RS-232 captive screw connector has	RS-232
the pin assignments as shown at right.
	Tx Rx G

SIS commands consist of one or more characters per field. No special characters are required to begin or end a command sequence. When the DSC 301 HD 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

DSC 301 HD 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 DSC 301 HD sends this response when a new signal is detected.

•HplgO X@ ] The DSC 301 HD sends this response when a hot plug event on output X@ is detected.
