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 number 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

processor Tx connects with the control device Rx and vice versa.

Both the rear panel RS-232 port and the front panel configuration port can
be used at the same time. Neither has precedence. The SSP 7.1 responds to
commands in the order received.

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 =

]

), which signals the

end of the response character string.
When the SSP 7.1 is first switched on, depending on the model, it sends the message:
(c) Copyright 2010, Extron Electronics, SSP 7.1, 60-842-01, V x.xx

]

where 60-842-01 is the catalog part number and V x.xx is the firmware version number.
