CAT
( Computer Aided Transceiver )
The CAT (Computer Aided Transceiver) System
in the FT-891 transceiver provides control of
frequency, VFO, memory, and other settings such
as dual-channel memories and diversity reception
using an external personal computer. This allows
multiple control operations to be fully automated
with single mouse clicks, or keystroke operations
on the computer keyboard.
Using the USB Cable
(Refer to figure 1)
Note: A USB driver is required for remote control
from a computer. Download the driver from
the Yaesu website (http://www.yaesu.com).
The FT-891 transceiver has a built-in USB to Dual
UART Bridge, allowing direct connection from
the rear-panel USB jack to the USB jack of your
computer without the need of any external boxes.
You will need a USB cable to connect to the USB
jack on your computer.

Overview
YAESU MUSEN does not produce CAT System
operating software due to the wide variety of
personal computers and operating systems in

in this chapter explains the serial data structure
and opcodes used by the CAT system. This
information, along with the short programming
examples, is intended to help you start writing
