COMMAND DEFINITION

<CMD>
Symbol

Value
<Param> Value Definition
AICH? 0x91 Command Packet:
The controller sends no
<Param> character in the
command packet.
This command causes the
CAT 860 to return a query
response packet where
the <Param> contains the
selection status set by AICH
(<0x90>).
If the command is not
received properly, the CAT
860 responds by sending a
<NACK> character.
Response Packet:
The CAT 860 sends only
one <Param> character in
the response packet. The
possible values are shown
below:
0x80 = TV/VCR
0x81 = CD/DVD
0x82 = COMPUTER
0x83 = AUX IN
0x84 = IR Channel A
0x85 = IR Channel B
0x86 = AUX OUT

COMMAND DEFINITION
CONT’D
Definition
This command determines which volume-level will be affected by the AIDI
(<0x92>), AIDD (<0x93>), and AIAV (<0x94>) commands.
If the command is properly received, the CAT 860 responds by repeating back
the command packet where the <Param> character contains the selection status.
If the command is not received properly, the CAT 860 responds by sending a
<NACK> character.
Power up default is TV/VCR selected.
These items are included for controllers limited to only a single volume control,
the three parameters on the left allow the AIDI (<92>), AIDD (<93>), AIAV, (<94>)
and AIAV? (<95>) commands to have the same capabilities as the AODI (<A2>),
AODD (<A3>), AOAV (<A4>), AOAV? (<A5>), IIDI (<B2>), IIDD (<B3>), IIAV
(<B4>), and IIAV? (<B5>) commands.
That is, multiple commands will be able to independently affect the values of
the same volume-level EEPROM variables which correspond to the IR CH-A, the
IR CH-B, and the AUX OUT. This is true even if the two commands have been
directed to the same volume-level EEPROM variable. In this case the EEPROM
variable retains the value from the last command issued from the serial controller.
