Hi everybody,
I am working for HEOL DESIGN company, and we are currently investigating 
this TS2100 1995 bug. We have developped the N024, a clone of Trimble 
ACE III receiver (which is mounted inside the TS2100). They are many 
issues with the TS2100-ACE III internal protocol, and we have good hopes 
to solve it out by N024 software.
I will keep people informed when this bug will be solved, on the Heol 
Design N024 web page. Then you will be able to purchase it.
Regards
