SIS Commands
You can use Simple Instruction Set (SIS) commands to configure the DA HD 4K distribution
amplifier. This section provides information about using those commands. The following topics

Introduction to SIS
The DA HD 4K series distribution amplifiers accept 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-pole captive screw connector on the rear panel (see
figure 2
,
E
, on
page 5) or to the config port on the front panel (see
figure 7
,
B
, on page 13).
The protocol for the remote port 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 distribution amplifier transmit
(Tx) wire connects with the control device receive (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 strings (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 DA HD 4K devices end with a carriage return and a line feed (CR/LF =
]
), which
signals the end of the response character string.
When the distribution amplifier is first switched on, it sends the message:
