<Param> Value Definition
IICH p 0xB0 Command Packet:
The controller sends only
one <Param> character in
the command packet. The
possible values are shown
below:
0x80 = IR Channel A**
0x81 = IR Channel B
** Power up default
Response Packet:
The CAT 860 sends only
one <Param> character in
the response packet. The
possible values are shown
below:
0x80 = IR Channel A
0x81 = IR Channel B
This command determines
which volume-level EEPROM
variable will be affected
by the IIDI (<0xB2>), IIDD
(<0xB3>), and IIAV (<0xB4>)
commands.
If the command is properly
received, the CAT 860
responds by repeating back
the command packet where
the <Param> contains the
selection status
If the command is not
received properly, the CAT
860 responds by sending a
<NACK> character.
Power up default is IR
Channel A selected.

IICH? 0xB1 Command Packet:
The controller sends no
<Param> character in the
command packet.
Response Packet:
The CAT 860 sends only
one <Param> character in
the response packet. The
possible values are shown
below:
0x80 = IR Channel A
0x81 = IR Channel B
This command causes the
CAT 860 to return a query
response packet where
the <Param> contains the
selection status set by IICH
(<0xB0>).
If the command is not
received properly, the CAT
860 responds by sending a
<NACK> character.

AOAV? 0xA5 Command Packet:
The controller sends no
<Param> character in the
command packet.
Response Packet:
The CAT 860 sends two
<Param> characters in
the response packet. The
possible values are shown
below:
<Param> #1:
0x81 = AUX OUT
<Param> #2:
0xCF = 0 dB
0xCE = -1dB
0xCD = -2dB
0xCC = -3dB
0xA7 = -40dB
0x83 = -76dB
0x82 = -77dB
0x81 = -78B
0x80 = -79dB
This command causes the
CAT 860 to return a query
response packet where
the first of two <Param>
characters contains the
selection status set by
AOCH (<0xA0>) and the
second contains the value
stored in the volume-level
EEPROM variable selected
by the AOCH (<0xA0>)
command.
If the command is not
received properly, the CAT
860 responds by sending a
<NACK> character.
