Review: Works with legacy equipment even when USB serial ports don't. - I have been trying to get the CAT port on my old Yaesu FT-847 working for some time now. Putting a scope on the Rx pin of the radio I noticed that the levels seemed very low at about 3 volts. This was using a USB serial port CAT cable purchased specifically for this radio. I thought why not try a more traditional serial port and ordered this product. Installation went smoothly and my Windows 11 PC soon showed two new serial ports. Connecting one to the radio with a F-F null modem cable and initialized everything at 4800 baud. Bang just like that the CAT port lit up and started working. Looking at the levels on the scope, they are more like 10 volts now.
Review: Drivers are available through Windows Update - Works perfectly - If you are running Windows 11 you do not need to use the CD to install the driver - Just go to Windows Update and go to Advanced Options - Driver Updates (You will need to do this twice as the first update is for the controller, the 2nd update is for the COM Ports themselves).

Works perfectly - If you are running Windows 11 you do not need to use the CD to install the driver - Just go to Windows Update and go to Advanced Options - Driver Updates (You will need to do this twice as the first update is for the controller, the 2nd update is for the COM Ports themselves).

### ⭐⭐⭐⭐⭐ Perfect for Ham radio
*by H***3 on January 29, 2024*

Purchased to connect my Kenwood 2000 and my Kenwood 590s to my computer and be able to run programs from Kenwood and Ham Radio Deluxe. Unit comes in a full style profile and needs to be separated to connect to a low profile style computer. I have big hands so it was a PIA for me but got it done. Installed CD and looked for windows 11 64 bit driver. Ran setup and it was done. Both radios connected without issues. Just make sure to setup your port for the radio. Mine was 5 and 7. Also if you have no Cd player you can do a search for the driver on the CD and it will be available for download for free.
