Connection to the radio
The transceiver should be connected to the computer in accordance with the rig's operating instruction manual. The appropriate connecting lead must be used.
Please note: although the FT-857 and FT-897 radios can operate CAT control through the Mic socket you cannot perform memory management this way - the firmware does not support it. You must use the 8-pin mini-din socket at the rear of the radio.
The Links page of the website lists sources of ready-made cables that can be ordered over the Internet.
If you have a FT-847 you need a null modem cable with a female connector at the radio end.
Assuming plug A to be the radio end of the cable:
plug A pin 2 connected to plug B pin 3
plug A pin 3 connected to plug B pin 2
plug A pin 5 connected to plug B system ground (pin 5 for a 9 pin plug, or pin 7 for a 25 pin plug).
If you have a FT-897, FT-897D, FT-857, FT-857D, FT-818ND, FT-817ND or FT-817 you need a TTL to RS232 level converter.
The Yaesu cable is a CT-62 but there are many designs for DIY.
If you are not up to soldering neatly, just buy a ready made cable.
COM port and speed
Selection of Com port number and speed is done from the initial screen. All rigs except the FT-847 use 9600 baud for clone operation regardless of the CAT operation speed. The FT-847 can clone at either 9600 or 57600 baud.
Detecting the COM port number
On the Tools menu there is a command called 'COM port Detector'. This will assist in determining which COM port your radio is connected to - particularly helpful with USB attachment of the programming cable.
Click the command 'COM port Detector' and the following screen is shown:
Follow the on-screen instructions to detect and set the COM port for your programming cable. Be aware that each USB socket on your PC may be allocated a different COM port number, so you might need to use this screen again if you change your usual socket.
If you have an FT-847 then click the button to show the usage instructions for that radio.
