RJR posted:I assume your TIU is not Rev L. You need a USB to serial adapter cable. Radio SHack has carried one by Gigaware, and Dell has them (another brand) in its catalog at half the R-S price, but plus shipping. You will also use that cable to hook an MTH wifi into the TIU.
RJR, my TIU is the Rev L. I was researching this problem online before I posted the above comments. I believe it has something to do with Windows 10 and it isn't the MTH software but I couldn't find an exact fix.
I will post the picture for you. I don't think GRJ will mind.
