hi not sure when this was last updated - I had being working on delivering TSIP to a 500 also but had to give up is this solution available to download/buy?
UBX to TSIP for ez250 is the only one that really works well at the moment. Not all TSIP is the same.
Right now its on hold for something much cooler agra-gps is working on.
I have to put AOG in my friends seeder then I can put some more serious hours into the 500. The Trimble units are pretty solid, but are kinda clunkers compared to ag open. CFX750 is even lagging behind AOG.
