Introduction to SIS

The SSP 7.1 accepts 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 9-pin D female to 2.5 mm TRS
Configuration cable (part # 70-335-01).
The protocol is 38400 baud, 8 data bit, 1 stop bit, and no parity.
NOTES: The wiring in the RS-232 cables crosses over so that the surround sound
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 SSP 7.1 ends with a carriage return and a line feed (CR/LF =
end of the response character string.
When the SSP 7.1 is first switched on, depending on the model, it sends the message:

catalog part number and V x.xx is the firmware version number.

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.
