Remember that the person with the most knowledge of your computer system is you. We wish we could be more helpful, but it is virtually impossible for us to debug your entire system on the telephone. The majority of problems encountered are software setup related, i.e. wrong COMM port, IRQ conflicts. Since we did not setup your system, it is unadvisable for us to recommend that you change your system settings. Please only call as a last resort and consult the warranty procedure before doing so.

TESTING YOUR INTERFACE:

Connect the radio as you normally would to a power supply, connect the interface cable to a communications port of your computer (COM1 or COM2), and connect the other end to the radio. If needed, remove your modem or other device to allow you to temporarily use one of these ports to test your interface. These ports tend to be more standardized than COM3 or COM4, so the program was not written to include the diversity of options available. Now run the program by typing in the following commands at the default prompt.

A:\COMMTEST.EXE (Where A is the drive that the install disk is in)

After making sure everything is set to go, look in your radio's manual under computer control. There should be a good general description of the codes required to perform certain tasks, data protocols (ie. , 4800, N, 8, 1) and so on.

Look up the protocol first, and then set it in Commtest by pressing "S" on the main menu. Follow the directions and answer the questions for baud rates, stop bits, etc. Then look up a simple code like setting the frequency or turning some feature on and off. Depending on how the manufacturer has set up the op codes in the radio will determine what format to use. For example the Yeasu 2.5200 Mhz, the op code needed is 0Ah, 01h, 42h, 50h, 00h. Note that 0Ah is the op code for setting frequency. The problem that you will find upon trying to send this code to the radio is that it needs to be sent in reverse order of what makes sense to you and me. The Yeasu FT- 900 radio requires that the codes be sent out in reverse order, so when entered into the program you will need to start with 00h and end with the code of 0Ah.
