Introduction to SIS

Both the RGB-DVI 300 and the RGB-HDMI 300 (A) accept SIS commands from a host device
such as a computer running the HyperTerminal 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 female 9-pin D to 2.5
mm TRS Configuration cable (part number 70-335-01).
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 video scaler Tx connects with the
control device Rx and vice versa.
Only one serial port can be used at a time. If the front 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 can be used interchangeably. Commands do not
require any special characters to begin or end the command string. Each response from the
video converter ends with a carriage return and a line feed
(CR/LF =
When the RGB-DVI 300, RGB-HDMI 300, or RGB-HDMI 300 A is first switched on, depending
on the model, it sends the message:
