COMMAND DEFINITION CONT’D
Definition: This command modifies the volume-level EEPROM variable which
was selected by the AICH (<0x90>) command. The EEPROM variable is
decremented by the amount indicated in the <param> character.
Afterwards, the value in the EEPROM variable is unconditionally loaded into the
corresponding volume control hardware register. This overrides any prior mute
operation.
If the command is properly received, the CAT 860 responds by repeating back
the command packet where the first of two replacement <Param> characters
contains the selection status set by AICH (<0x90>) and the second contains the
resultant value stored in the volume-level EEPROM variable which was modified
by this command.
If the command is not received properly, the CAT 860 responds by sending a
<NACK> character.
For the audio inputs, the power up default values for all six input volume-level
EEPROM variables is set for -40dB.

AIDD p 0x93 Command Packet:
The controller sends only
one <Param> character in
the command packet. The
possible values are shown
below:
0x81 = one 1dB step
0x82 = two 1dB steps
0x83 = three 1dB steps
0x84 = four 1dB steps
0x85 = five 1dB steps
0x86 = six 1dB step
0x87 = seven 1dB steps
0x88 = eight 1dB steps
0x89 = nine 1dB steps
0x8A = ten 1dB steps
Response Packet:
The CAT 860 sends two
<Param> characters in
the response packet. The
possible values are shown
below:
<Param> #1:
0x80 = TV/VCR
0x81 = CD/DVD
0x82 = COMPUTER
0x83 = AUX IN
0x84 = IR Channel A
0x85 = IR Channel B
0x86 = AUX OUT
<Param> #2:
0xCF = 0 dB
0xCE = -1dB
0xCD = -2dB
0xCC = -3dB
0xA7 = -40dB
0x83 = -76dB
0x82 = -77dB
0x81 = -78B
0x80 = -79dB
