CAT Remote Control
6.1
General Specifications
The FDM-DUOr receiver uses a full-duplex, asynchronous, USB serial interface for communicating
through the USB CAT port. Each data is constructed with 1 start bit, 8 data bits, 1 stop bit, no parity is
used (8N1). The baud rate is selectable in the [70] CAT BAUD menu. Available values are 9600, 38400,
57600, 115200 bps.
The FDM-DUOr implements proprietary commands and also a subset of the Kenwood TS-480 command
set. Some of those TS-480 commands have no effect on the receiver, they only ensure the compatibility
of the FDM-DUOr with Ham Radio Deluxe.
6.2
Commands Types
A CAT command is composed of an alphabetical part, various parameters and a terminator that signals
the end of the command. For example to set the VFO-A to 14MHz the command is: “FA00014000000;”
with :
“FA”: alphabetical command,
“00014000000”: parameter,
“;”: terminator.
CAT commands can be classified as shown below:
EXAMPLE
To set the VFO-A to 14MHz the PC sends the
SET command type
“FA00014000000;”
To read the VFO-A frequency the PC sends the
READ command type
“FA;”, the
ANSWER
response type
is returned to the PC: “FA00014000000;”.
NOTE
Some particular rules about the CAT commands on the FDM-DUOr :
not all the commands have the three types of command/response (
SET
,
READ
and
ANSWER
),
normally, send the
SET command type
will not cause the FDM-DUOr to send the
ANSWER
response type
but if a command does not have a
READ command type
and has the
SET and
ANSWER type
, then send the
SET command
will cause the FDM-DUOr to send the
ANSWER
response type
.
