Connection to the radio


Ready made cables

The radio comes with a Yaesu CT-169 programming cable. This cable has a DB9 serial connector for your PC. If you do not have a 9 pin serial port on your PC you will need a USB to serial adapter.

Yaesu also produce the SCU-18 USB  PC connection cable. This requires USB driver software to be installed. If you can not find your CD then download it from the Yaesu web site.


COM port connection

Selection of the Com port number is done using the Settings menu. The program will remember the selection you make for the next time you run. 

There are two commands available - 'COM port Detector' and a pop-out called 'COM Port'. If you are certain about your COM port number then it is quickest to use the 'COM Port' pop-out. Otherwise use the 'COM port Detector' command. The following screen shows the result of detecting a Com port:



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 might be allocated a different COM port number, so you may need to use this screen again if you change your usual socket. You may not see your COM port if you are running a PDA hotsync program that has acquired all of the COM ports. Stop the hotsync program and try again.
