Installing G8BPQ’s CAT7200 for IC-9100 PTT Control

If you plan on using UISS with SoundModem on your IC-9100, then you are going to need to obtain a copy of the CAT7200 program by John Wiseman (G8BPQ) to deal with the PTT function.

1. First, obtain a copy of CAT7200 here
2. Create a directory on your computer like C:\CAT7200 and copy the files out of the ZIP file you downloaded above.
3. The Virtual Com Port Driver must then be installed.  I’ve taken the liberty of converting John Wiseman’s (G8BPQ) instructions from html format on his website to a PDF that can be found here.  Be sure to use the correct version for your OS (32 or 64 bit).  These instructions document how to install the Virtual Com Port Driver on Win 7 and up.  It worked just great on Win 10 32 bit version.

After following the instructions above, you will see a COM port appear under Device Manager.  In my case it was COM7:

Now run the CAT7200.EXE program, and you will see a screen like this:

On the left hand side, select the same COM port as you saw in Device Manager — in my case COM7.

On the right-hand side, select the COM port where your IC-9100 gets its CI-V commands.  In my case that is COM5, the lower port # when the Icom drivers were installed (see the Device Manger shot above showing the two SiLabs USB to UART Bridges at COM5 and COM6).

Select the CI-V Baud Rate (See IC-9100 Menu #60), and the CI-V Address (See IC-9100 Menu #61).  In my case that was 19200 baud and 60h.

Finally click the “Open” button.  That’s it.  You can minimize the screen or leave it running in the background.

When you are all done, and have shut UISS down, you can then click close the CAT7200 window.
