You could even use the one off a 10K drive if you're working on a 50-04. The UIT is great and it has worked on every UDC I've tried, I was so surprised when I figured it out since I work for the company in question and no one seems to know this. Even with IMS the UIT can save a lot of time and energy depending on how far away the machine room is.

If your Hyperterminal session keeps saying bad data packet it usually works anyway but PM if you want the settings to make it work correctly, or the software.

Another good trick with the UDC is to get the 5 pin plug for Con11 and wire a cord to it, you can plug it right into the wall and put your Generic and profile in the door board from the machine room, or the shop for that matter, and never have to set your computer up on the car top. If you have the UIT, you don't necessarily even have to have a computer with IMS on the job.
