Dear All, More and more people are starting to play with the Thunderbolts. I already received mine :-) Now playing around with them.
First I powered it up and connected it to the normal serial port of the PC. The Thunderbolt behaved fine, self survey took some time, because the antenna is inside a concrete building with very limited view to the sky. However, next I did a test with the same Thunderbolt but now it was connected to a USB to Serial converter (brand is Sweex). After switchinhg it off and on, I expected the same behaviour as when it was connected to the "real" serial port. But... it started to behave very strange... instead of starting a normal survey, it started disciplining after a couple of minutes (almanac was not even valid). The DAC-voltage clipped to the power rail, and the SV and AMU-fields remained "?". Resetting (hot, cold, factory default) didn't make any difference. When power cycling the unit and connecting it back to the normal serial port the normal behaviour returned. I assume it has something to do with the USB to serial converter. Is there anyone else with similar experience? Or who has used a USB to serial converter with succes? Thank you, best regards, Jeroen -- Ing.
