This section defines the ASCII command set of the AV5103 System Controller. The commands
that are available depend on whether the command set was selected as an “amplifier” or “source”
device. All commands are available when called as an “amplifier” device. A subset of these
commands are available when called as a “source” device, as shown in the following table. If a
command which is not currently available is received the !r?<CR> response is returned, to say that
the command was not understood.
The input select commands, [rAINP=p], [rVINP=p] and [rDINP=p] operate on different audio and
video outputs, depending on whether they are called as an “amplifier” or “source” device. The
“amplifier” device commands route the selected audio and video components to the main output
connectors, while the “source” device commands route their output to the multi-room connectors, as
shown in the following table.

When the AV5103 is installed in a system, its audio and video inputs and record outputs are defined
as audio only (A), video only (V) or video with linked audio (AV). An AV pair is selected by
referring to its video connector, the linked audio connector being selected automatically by the
AV5103 (see [rDINP=p] and [rDREC=in,out] commands).
