I haven't used a Leica that old, but I remebmber having to buy a special chord to get the TCRP1100 to work with newer computers, because they do not see the serial port like older ones do, or in my case they didn't have one. You generally have to set up the baud rate and a few other settings to make it happen. You can download a copy of leica geo office tools at leica myworld. You can also try to covert it to an ASCII P,N,E,Z,D. You can do that in word. Good luck with it.
Here is a good tutorial on the Leica Data Transfer utility. Copy and paste the whole link or it won't work.
try this link. its a pdf. see pages 156-157. I believe this works with the model you have. If not, call g360 (geomatics 360), in Zachary, LA. Ask for Don Biggs. He bleeds green (leica green). He can answer or get the answer for anything leica.
Leica . Had software called TC Tools that is used for TS transfers for those models. Up and down loads.
I do not know where you could find it . Leica may help.
