To enter these codes into the program, press “O” on the main menu, then choose the type of data transfer you require. In the case of the Yeasu FT- 900, you would choose “Enter Hex”. Now you can enter your code in, and in case of the Yeasu and possibly others, enter the code in reverse.

Now you can press "1" or "2" on the main menu depending on which comm port you are using. If you accidently press the comm port where your mouse is running, it may disable your mouse temporarily until you restart another program. Watch carefully on the radio to see if anything happens when you transmit this data through the interface.

If the radio is receiving the data it means that your interface cable is operating properly. If the display shows that it is receiving the data, but no action occurs, check the op code you are using to make sure it is being entered in the correct order, as well as the correct op code. If so, check your comm specs again.

Naxt try to send out a code that returns some information-such as to retrieve the operating frequency. This will help to verify that your receive data line is operational also. Set up the comm specs as before and then enter an op code that returns data. Now Comm test should show you the data it has received after sending out the op code. If you are able to receive something, rejoice, everything should work for you. If not, you will want to check everything out, such as; your wiring, certain functions being enabled on the radio, the correct op codes being used, and so on. If you are still having trouble, have a fellow computer wiz help you out, maybe there is something you missed.

Also note that not all radios send back their information in ASCII type code. Most of the information they send back is encoded information, which when displayed on the screen will look like Greek to most of us. You don't really need to decode the information unless you are really expecting ASCII and did not get it. If that is the case, you may wish to check the clock speeds of your radio or computer, either that or turn the computer off, and then on again to reset the serial ports. This is a problem beyond the scope of the interface cable and the solution is in your existing hardware.
