The adapter that is recommended by MSD was and may still be is called iogear usb serial adapter part number GUC232A. I use the one from my MSD box to my laptop . Keep in mind sometimes I have to look for the port it is using . Some times I have my laptop off with the box connected and on, then i turn on my laptop and the ports seem to find each other I think .Not sure if this would help other devices but it so far is another option for all to spend more money on Lol at me
.a person can buy the adapter on line is best I hope this link works
