Any recommendations for one. SnapAV recommends Trip Lite but they look cheap.

they work. I have 2 of them.

You want the Keyspan [Link: tripplite.com]

I'll give that one a try, wondering if I should order something else too. For a back up in case it doesn't work.

The Keyspan devices are the best I have ever used.

I've had good results with Keyspan.

IOGear GUC232a I’ve never had a device it didn’t work on. `

Post 6 is what I have and used for many many years. Never let me down.

I gave up. The GoldX I have didn't work reliably enough and it wasted a lot of my time when I used it with three different computers, so I started using a computer given to me by a client. I would look for a used laptop and update the OS before I would try another adapter.

This one saved me last year. I was 2 hours from the shop, and needed to update a Tekmar gateway. Of course, I had to break the PCMCIA adapter I had trying to get it plugged in, and hooked up. I was SOL. Then I remembered there was a Radio Shack in the lumber store in town. I hopped over there and explained what I needed, and the associate was helpful and actually knew what I was looking for, and found what he considered the "only one left in the state" and that I was lucky.

I have the Keyspan one as well, and a Belkin model. All 3 work when I make them work. :)

I have a collection of about 6 different ones. I've found with windows 10, it's always a shot in the dark at which one will work with a manufacturer's software.

So look for a 10 year old laptop with a serial connection?

Keyspan

Doesn't need to be 10 years old, but I got lucky- my client runs a company that designs and installs displays, like the ones in car dealers, malls and other places- the ones where this computer were for HTC phones and when HTV called to tell him they were done with that ad campaign, he had a ton of good equipment to do with as he pleased.

The one I'm using is from dfi Technologies and the model is M110/515

I think that as long as the computer is healthy, it's a good bet- this works so well that I won't even bother with the adapter anymore. It wasted so much time I don't want to look at it and the last time I used this computer to program a remote, it was the same MX850 that gave me fits in 2013-2015. He moved and added/deleted some equipment, so I got the job of reprogramming and it took a fraction of the time, I didn't need to assign a USB port and life was good.

I have 1 from monoprice for years that still works with Windows 10. I also have backup units I bought cheap from amazon that work also.

This makes sense. On the other hand, back in Pronto days the Keyspan was THE ONE to have. It's never failed me once. (With URC MX850s it's failed me repeatedly, but hey -- it's never failed me once!)
