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.

allowing direct connection from the rear-panel RS-232C
jack to the serial port of your computer without the need
of any external boxes.
When using the RS-232C cable, set Menu item
[OPERATION SETTING] → [GENERAL] →
[TUNER/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 conguration). 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.

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.

Control Command
Operation
A computer control command is composed of an alphabetical command, various parameters, and the terminator
that signals the end of the control command.
Example: Set the MAIN Band frequency to 14.250000
MHz.
FA 014250000 ;
Command Parameter Terminator
There are three commands for the
below:
command: Set a particular condition
Set
command: Reads an answer
Read
Answer
For example, note the following case of the FA command
(Set the MAIN Band frequency):
To set the MAIN Band frequency to 14.250000 MHz,
the following command is sent from the computer to
the transceiver:
“
To read the MAIN Band frequency, the following
command is sent from the computer to the transceiver:
“
When the Read command above has been sent, the
following command is returned to the computer:
“FA014250000;
command: Transmits a condition
FA014250000;
” (Read command)
FA;
” (Set command)

Alphabetical Commands
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.
Parameters
Parameters are used to specify information necessary to
implement the desired command.
The parameters to be used for each command are predetermined. The number of digits assigned to each parame-
ter is also predetermined. Refer to the “Control Command
List” and the “Control Command Tables” to configure
the appropriate parameters.
When conguring parameters, be careful not to make the
following mistakes.
For example,
)
)
)
when the correct parameter is “IS00+1000” (IF SHIFT):
IS001000;
Not enough parameters specied (No direction (+)
given for the IF shift)
IS00+100;
Not enough digits (Only three frequency digits
given)
IS00_+_1000;
Unnecessary characters between parameters
IS00+10000;
Too many digits (Five frequency digits given)
Note: If a particular parameter is not applicable to the
DX101D
character except the ASCII control codes (00 to 1Fh) and
the terminator (;).
, the parameter digits should be lled using any
FT-
Terminator
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.
