CAT (Computer Aided Transceiver)Operation
Overview
The CAT (Computer Aided Transceiver) System in the FT-710 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.
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.
Using the USB Cable (CAT-1 / CAT-2)
The FT-710 transceiver has a built-in USB to Dual UART Bridge, allowing direct connection from the rear-panel
USB jack to the USB jack of a computer without the need for an interface device, simply use a USB cable to
connect to the USB jack on the computer.
To connect to a PC using a USB cable, a Virtual COM port driver must be installed on the PC.
Visit the Yaesu website http://www.yaesu.com/ to download the Virtual COM port driver and Installation Manual.

How to Conrm the Installation, and the COM Port Number
After the FT-710 and computer are connected, conrm that the virtual COM driver has been installed successfully:
1. Press and hold the ON/OFF switch to turn the transceiver ON.
2. Connect the transceiver and PC with a commercially available USB cable (A-B).
3. Open the “Device Manager” screen in Windows.
4. On the Device Manager screen, double-click “Port (COM & LPT)”.
“Silicon Labs Dual CP210x USB to UART Bridge : Enhanced COM Port (COM**)”
“Silicon Labs Dual CP210x USB to UART Bridge : Standard COM Port (COM**)”
*(The number in the “(COM**)” portion may vary from computer to computer.)
The above example indicates that COM5 can be used for CAT communications (CAT-1), while COM6 can
be used for TX control (PTT, CW Keying, Digital Mode Operation) or CAT communications (CAT-2).
When performing software port conguration, select the COM port numbers that were conrmed using the
procedure above.
If a “!” or “X” is displayed for the port on the Device Manager, uninstall and reinstall the virtual
COM driver.

CAT (Computer Aided Transceiver)Operation
The FT-710 contains two virtual COM ports, an Enhanced COM Port and a Standard COM Port.
These ports o󰀨er the following functions:
• Enhanced COM Port (CAT-1): CAT Communications (Frequency and Communication Mode Settings)
• Standard COM Port (CAT-2): TX Controls (PTT control, CW Keying, Digital Mode Operation) or CAT
Communications (Frequency and Communication Mode Settings)*
When performing software port conguration, select the COM port numbers that were conrmed using the
procedure above, use the two conrmed COM port numbers for each software function. The frequency and
communication mode and PTT control can be set from the software, and CW keying, digital communication,
etc. can be performed simultaneously.
*NOTE: (When using a standard COM port (CAT-2) for CAT communication (setting frequency, communication
mode, etc.) and using hardware ow control by RTS or DTR, be sure to set the following menu items to “OFF”
(factory default) or set to “DAKY” to disable PTT control by RTS or DTR.)

PRESET PRESET1 - 5 RPTT SELECT OFF / RTS / DTR / DAKY
• If a transceiver with a di󰀨erent serial number is connected and turned on, di󰀨erent COM port numbers
will be assigned to it, making it possible to perform individual COM port congurations for separate
transceivers.
• When using the USB cable for TX control, the transceiver may switch to the transmit mode when the
computer is started.
• Always close the application on the computer before disconnecting the USB cable.

CAT (Computer Aided Transceiver)Operation
Using the RS-232C (CAT-3)
The TUNER/LINEAR jack on the rear panel can be used for CAT communication (5V TTL level serial communication).
Set to “CAT-3” in the setting menu [OPERATION SETTING] → [GENERAL] → [TUN/LIN PORT SELECT]. (Factory
setting: EXT-TUNER)
• Since the serial communication of this jack is 5V TTLlevel, it cannot be directly connected to the RS-232C
terminal of the PC.
• The connection cable must be prepared by yourself using the optional band data cable CT-58
(mini DIN 8-pin to DIN 8-pin).
• CAT communication cannot be used simultaneously with an external antenna tuner or linear amplier.

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.
Example: Set the VFO-A frequency to 14.250000 MHz.
FA 014250000 ;
   
Command Parameter Terminator
There are three commands for the FT-710 as shown below:
Set command: Set a particular condition (to the FT-710)
Read command: Reads an answer (from the FT-710)
Answer command: Transmits a condition (from the FT-710)
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 trans-
ceiver:
“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)
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 param-
eter is also predetermined. Refer to the “Control Command List” and the “Control Command Tables” to congure
the appropriate parameters.
When conguring parameters, be careful not to make the following mistakes.
For example,
when the correct parameter is “IS00+1000” (IF SHIFT):
IS001000;
Not enough parameters specied (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 FT-710, the parameter digits should be lled using any
character except the ASCII control codes (00 to 1Fh) and the terminator (;).
Terminator
To signal the end of a command, it is necessary to use a semicolon (;). The digit where this special character must
appear di󰀨ers depending on the command used.
