FTDX10 CAT Control Problem Solved!

Following on from my article about the issues I had with the Silicon Labs VCP/USB to Serial driver that’s required to be able to use the CAT controls on the FTDX10 via the USB connection I decided to take a different approach to the problem.

Since the driver was incompatible with something that is already installed on my MacBook Pro (Most likely Virtualbox) and rendered the computer unusable I decided to search for a USB to Serial converter that worked with Apple computers without the need for proprietary drivers.

It didn’t take long to find a suitable adapter, the Sabrent USB 2.0 to Serial (9-Pin) available on Amazon uses the FTDI chipset that is natively supported by Apple MacOS without the need for proprietary drivers to be installed. This makes it a simple plug and play adapter.

Unfortunately both the adapter and the FTDX10 have a male DB9 connector and so a female to female DB9 adapter is also required to make the connection.

Connecting the DB9 to the FTDX10, setting the RS232 port to 38400 on the radio and within the WSJT-X software I soon had control of the radio from the MacBook Pro.

To get the sound from the radio to the MacBook all I needed to do was connect the USB lead into the back of the radio and into the 2nd USB port on the MacBook. Since the sound card in the FTDX10 is supported natively by MacOS 11.6.2 (Big Sur) without the need for the Silicon Labs driver, this completed the setup.

So I now have full digital modes and rig control without installing any proprietary drivers on my MacBook Pro.

I tested the setup using FT8 on 30m this afternoon, it worked seamlessly.

Problem solved!

Silicon Labs VCP Driver for FTDX10 CAT Control Issues

To get my MacBook Pro talking to the Yaesu FTDX10 CAT controls so that I could use WSJT-X and FT8 I had to install the Silicon Labs CP210x VCP Driver so that it recognised the USB to Serial connection within the radio. This initially worked well however, over time I found my MacBook Pro started misbehaving.

The problem I had was that the MacBook Pro would wake from sleep but, the screen wouldn’t come on. The same issue occurred when booting the MacBook Pro from cold, the machine would boot but, the screen wouldn’t come on. Sometimes the screen would flicker during a cold boot and then eventually stay on, only to go off again permanently if the MacBook went to sleep.

I uninstalled the driver but, the problems continued. After much investigation the only thing left was to reinstall MacOS Big Sur.

Fortunately the way MacOS is configured, it’s possible to reinstall the O/S without losing any of the applications and data, a great relief for sure. I do have a Time Machine backup just incase though!

MacOS reinstalled and stability has returned once more, so it’s definitely the driver that has caused the screen problem.

So I’ve now raised a case with Silicon Labs asking for assistance resolving the issue, hopefully I’ll get a response.

I also put a message on the wsjtx.groups.io message board to see if anyone else has experienced this issue, so far no one has responded.

I’ll update the blog with any progress.

More soon …
