0x81 = IR Channel B
** Power up default
Response Packet:
The CAT 860 sends only
one 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 contains the

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
characters contains the
selection status set by
AOCH (<0xA0>) and the
second contains the value
