Hi Jef,
Thanks for responding. I'm now using my main Windows 10 (64-bit) machine with Subsurface 4.6.3.
Yes, I have the latest Silicon Labs CP210x USB to UART Bridge drive installed. When I go to the Mares website:
and download and run the executable, I get the message that the driver is already installed. I have attached a screenshot
of my hardware setup showing the driver version.
The Mares Puck Pro I have only has 20 dives on it, and the Battery status level says it is OK.
Searching through some Amazon comments, a user noted that for the Mares Dive Link 2 cable I'm using,
it will glow green when the USB is powering it, and then red when a successful connection is made.
The light has yet to turn red, so that is certainly a problem!
My Windows 10 screen shot of Subsurface and the error is also attached.
The dive computer is in PC Ready mode.
