Lasse & Richard
Further to your discussions regarding interfacing the Jupiter TU60-D120. 
There would seem to be a number of varieties of these units which one would 
expect to find some common interface connections and software control, but I 
gather this is not the case.
I am currently trying to set up two varieties, one is the TU30-D200 and the 
other is the TU30-D145, the latter being the simpler "Tracker" type. Can 
anybody confirm the connection field for each of these types as they do not 
seem to correspond to some printed/down-loaded data that I have ?
I would appreciate any information on these two units.
Roy
