CAT (Computer Aided Transceiver) Operation
Overview
Connection
The CAT (Computer Aided Transceiver) System in
the FT-991 transceiver provides control of frequency,
VFO, memory, and other settings such as dualchannel 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.

⑤④ ③ ②①
Using the RS-232C Cable (Refer to figure 1)
The FT-991 transceiver has a built-in level converter,
allowing direct connection from the rear-panel CAT jack
to the serial port of your computer without the need of
any external boxes.

When using the RS-232C cable, set Menu item “028
GPS/232C SELECT” to “RS232C”.
You will need a serial cable for connection to the RS232C (serial or COM port) connector on your computer.
Purchase a standard serial cable (not the so-called “null
modem” type), ensuring it has the correct gender and
number of pins (some serial COM port connectors use a
9-pin rather than 25-pin configuration). If your computer
uses a custom connector, you may have to construct the
cable. In this case, refer to the technical documentation
supplied with your computer for correct data connection.

Note:A USB driver is required for remote control from
a computer. Download the driver from the Yaesu

The FT-991 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.

YAESU MUSEN does not produce CAT System
operating software due to the wide variety of personal computers and operating systems in use today.
However, the information provided 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 programs on your own. As
you become more familiar with CAT operation, you
can customize programs for your operating needs
and utilize the full operating potential of this system.

CAT (Computer Aided Transceiver) Operation
Control Command
A computer control command is composed of an alphabetical command, various parameters, and the terminator
that signals the end of the control command.
Parameters
Example: Set the VFO-A frequency to 14.250000 MHz.
The parameters to be used for each command are predetermined. The number of digits assigned to each
parameter is also predetermined. Refer to the “Control
Command List” and the “Control Command Tables” to
configure the appropriate parameters.
Parameters are used to specify information necessary to
implement the desired command.

Command ParameterTerminator
There are three commands for the FT-991 as shown below:
When configuring parameters, be careful not to make
the following mistakes.
Set command: Set a particular condition
(to the FT-991)
Read command: Reads an answer
(from the FT-991)
Answer command: Transmits a condition
(from the FT-991)
For example,
when the correct parameter is “IS0+1000” (IF SHIFT):
IS01000;
Not enough parameters specified (No direction (+)
given for the IF shift)
IS0+100;
Not enough digits (Only three frequency digits
given)
IS0_+_1000;
Unnecessary characters between parameters
IS0+10000;
Too many digits (Five frequency digits given)
For example, note the following case of the FA command (Set the VFO-A frequency):
 To set the VFO-A frequency to 14.250000 MHz, the
following command is sent from the computer to the
transceiver:
“FA014250000;” (Set command)
 To read the VFO-A frequency, the following command is sent from the computer to the transceiver:
“FA;” (Read command)
 When the Read command above has been sent, the
following command is returned to the computer:
“FA014250000;” (Answer command)
Note: If a particular parameter is not applicable to the
FT-991, the parameter digits should be filled using any
character except the ASCII control codes (00 to 1Fh)
and the terminator (;).
Terminator
Alphabetical Commands
To signal the end of a command, it is necessary to use
a semicolon (;). The digit where this special character
must appear differs depending on the command used.
A command consists of 2 alphabetical characters.
You may use either lower or upper case characters. The
commands available for this transceiver are listed in the
“PC Control Command Tables” on the following pages.
