I had intermittent terminations of the USB link of LVB Tracker using the
internal LVB Tracker USB to serial port adapter header with SATPC32 . I
tried many different configurations to resolve and it pretty much failed
during every satellite pass at least once when I tried to use it.
I would have to close SATPC32 and close ServerSDX manually , turn off
the El-AZ controller power and then back on to reset the USB link,
restart SATPC32 and then it would work again till the next USB link
failure. It occurred randomly, but often enough to be a problem.
This occurred with three different computers running Win-XP, Vista and
As others have suggested, I replaced the USB adapter header assembly
with a MAX-232 and now use an external ATEN USB to serial adapter.
I have had no problems with LVB Tracker for over a year since doing
this. Rock solid!
