Audio DSP SIS Commands
DSP SIS command structure
Several digital signal processor (DSP) functions can be configured using SIS commands.
Commands entered via PCS are also displayed on the host communication utility screen
that is being used for SIS commands (for example, Extron DataViewer).
DSP control commands are a subset of the SIS commands with a specific structure.
• For a Set command, the form of the command string is:
E
<parameter ID><OID>*<value>AU
}
where:
• <OID> (Object ID) is a six-digit integer identifying the processor (see the Object
Identification Number table on page 85).
• <Parameter ID> is a letter identifying the parameter.
• <Value> is a number indicating the level being set for the parameter.
• For a View (Get) command, the value parameter can be eliminated, so that the
command structure for viewing a single parameter is:
E
<parameter ID><OID>AU
}
• The unit response to these commands begins with Ds. The response format is:
Ds<Parameter ID><OID>*<value>

E
= Escape
X10)
= Object ID (OID) number See the Object Identification Number table.
X11)
= Gain value Levels use a 10x multiplier system with no decimal
places. For example, a level of +10.4 dB would be
entered as 104 and a level of -3.2 dB would be
entered as -32.
