Does any one know about protocol IEC 62056-61??

I’m trying to get information trough IRDA when I search on the manual it says that the protocol is accord to IEC 62056-61.

I saw many other discussions sou the IEC 62056-21, but I think this one does not work in my project.

Actually I am really lost right now!! Any body can help me??

I’ve done this in the past, and even when given the userID and password... Just keep in mind the data is encrypted once you get it, or need to sendback to the meter...
