Sony Receiver commands (DSP:192; 112)

 

These seem to be the codes for the preamp/amp part of the receiver, like regular Sony device 16.There are probably discrete volume level commands that no one has discovered yet.

80

 

<audio input> [<video input> <surr mode>]

Change to specified input and surround mode.I think this can be used to select separate video and audio inputs for output, which is why there are two input parameters (normally you would want the video to match the audio).The video one seems to be optional, and it will select what you expect it to if omitted.Audio inputs with no video take 254 for the video input parameter.Iíve never seen the surround mode parameter documented, so I donít know what it does.Both the second and third parameters seem to be optional.

82

Query input (?)

128

 

should be <volume>

This, at least in theory, would set the volume to a specified level.It doesnít seem to work however.

129

 

<video loop>

Set video loop status

130

 

<audio input> <video input>

Sets the audio split, although this seems to work the same way as command 80.

131

<audio type>

Changes the audio input type for the current input between analog/coax/optical/etc.

133

 

<audio decode>

Sets audio decode mode.

134

 

<dimmer level>

Sets display dimmer level.

135

 

<output level>

Sets output level.

<audio type>

Audio type code number.

0 = Auto

1 = Optical

2 = Coax

3 = AC3 RF

4 = Analog

<dimmer level>

Number representing the display dimmer level.The source I got this from said the range is ď19 Ė 46Ē, but I donít know if thatís in decimal or hex or what.It doesnít make much sense to me.

<input>

<audio input>

<video input>

The inputís code number.Here is the list:

0 = Tuner

1 = Phono

2 = CD

<surr mode>

unknown

<video loop>

0 = off, 1 = on
