If you are using a laptop then MTH recommends you purchase a KeySpan Tripp-Lite Model:USA-19HS USB Serial Adapter to connect from the laptop to the TIU. I got it on Amazon for around $20.00
This Keyspan adapter worked perfectly to upgrade my Legacy system, but I was never able to make this adapter cable work with MTH's DCS loader program. Fortunately I had a Rev L TIU and once I found the correct USB cable the DCS loader worked perfectly that way. This was with the current 2.34 version loader.
I was doing all this with an old Windows 7 PC that had a ton of stuff loaded on it and a ton of it removed over several years of use. Could have been a conflict with something and the DCS program? However, the Keyspan adapter worked just fine with the Legacy system from the same PC, so I was never really sure what was wrong.
