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).
NOTE: These commands apply only to the DTP2/XTP/HDBT output (output 2).
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 five-digit integer identifying the processor (see
(OID)
on page 20).
•
<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> ]
