Where did you get the discrete on and off codes for the first address?

If that was from one of the code sets in the MX-850's predefined library (as opposed to learned signals or signals brought in by Universal Browser), which predefined code set was it?

If I can look at the discrete on and off signals for the first address, I can probably tell you how to get them for other addresses via Universal Browser. My own copy of the MX-850 software is a bit out of date, but hopefully that won't be an issue.
