2.4 Precautions
Connect the receiver only to a power source described in this manual.
Take care when plugging in cables, avoid applying sideways pressure that might damage the
connectors.
Avoid operating in wet conditions.
For better performance and safety, connect the receiver to good earth ground using a short,
heavy, braided cable.
Ground all outdoor antennas for this receiver using approved methods. Grounding helps protect
against voltage surges caused by lightning. It also reduces the chance of build-up of static
charge.

7 CAT Remote Control
7.1 Introduction
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-DUO implements proprietary commands and also a subset of the Kenwood TS-480 command
set. Some of those commands have a dummy implementation for compatibility issues with Ham Radio
Deluxe.
7.2 Computer control commands
A computer control command is composed of an alphabetical command, various parameters, and the
terminator that signals the of the command.
For example to set the VFO-A to 14MHz the command is:
Computer control commands can be classified as shown below:
EXAMPLE
To set the VFO-A to 14MHz the PC sends: “FA00014000000000;” SET command
To read the VFO-A frequency the PC sends: “FA;” READ command
When this command has been sent, the following message is returned to the PC:
