Introduction to SIS

The DP DA2 accepts SIS commands from a host device such as a computer running the Extron DataViewer utility or other control system. The host device can be connected to the 3-pin captive screw connector on the rear panel or to the config port on the front panel. To connect to the config port, use the optional Extron USB CFG cable (part number 26-654-06).

The protocol is 9600 baud, 8 data bits, 1 stop bit, and no parity.

NOTES:

•The wiring in the RS-232 cables crosses over so that the DP DA2 Tx connects with the control device Rx and vice versa.

•Only one serial port can be used at a time. If the config port is in use, the rear captive screw connector must be disconnected from the computer or other control device. Likewise, if the captive screw port is in use, the config port on the front panel must be disconnected from the computer or other control device.

SIS commands consist of a string (one or more characters per command field). Unless otherwise stated, upper and lower case characters may be used interchangeably. Commands do not require any special characters to begin or end the command string.

Each response from the DP DA2 ends with a carriage return and a line feed (CR/LF = ]), which signals the end of the response character string.

When the DP DA2 is first switched on, it sends the message:
