Yaesu FT-736R Operating Manual page 46

if the above frequency had been 1295.00000
MHz, the Frequency parameters would be;
C9h 50h 00h 00h
The first 23 instructions in the Chart
simply alter operating settings in the
transceiver, without
any data being
returned to the computer from the trans-
ceiver (on the
Serial Output line).
However, the last two instructions in the
Chart cause the FT-736R to return a Data
Block to the computer: in both of these
cases, the returned block will contain four
copies of either the squelch status or S-
meter value (in the first four bytes),
followed by an echo of the instruction
opcode (either 0E7h or 0F7h). This Data
Block is returned within a hundred or so
milliseconds after sending the Command
Block, so any controlling software must be
ready to read the Data Block very quickly
after sending the Command Block.
The exception to the 5-byte Block rule is
a special 15-byte Message Block sent from
the FT-736R to the CAT line whenever an
AQS digital message is received. An AQS
digital message is a 14-character self-
error-correcting (Hagelburger NRZ)
encoded packet sent over the air at 1200
bits/sec MSK in the FM mode. Firmware in
the main microprocessor of the FT-736R
applies error-correction and decodes these
characters and the message number (from
1 to 4), passed to the CAT system in the
last byte, as follows:

CTCSS TONE CODES
This data is significant only if
the
optional FTS-8 Tone Squelch
Unit is
installed. Note that CTCSS tones are only
active in the FM mode; that the T ENC
switch on the front panel must be pressed
for the tone to be transmitted.
