Connection to the radio


Cables

The radio is connected to the computer using a programming cable. The Links page of the website lists sources of ready-made cables that can be ordered over the Internet as well as several USB/serial adapters and DIY circuit designs. 

DIY information

The radio requires a 4-way plug with a narrow neck that will permit it to fit into the recess around the socket. Tip is unused, ring 1 is data, ring 2 is unused, sleeve is GND. This picture of the socket shows the recess into which the plug must fit in order for the internal connectors to line up.



Further information on plugs, adapters and programming cables including DIY circuits can be found on the Links page of the author's website.

COM port

Selection of 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 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 will be allocated a different COM port number, so you may need to use this screen again if you change your usual socket.
