Hi Bennett,

The chances are the problem is in the data exchange from Nova - Comm port - USB driver. The LVB Tracker is a data receiver and then it acts on the data. I have an LVB Tracker running off a IBM laptop and a Compaq tower, both using XP. I am using SatPC32 on both computers. The laptop drops the comm link sometimes, but the tower is rock solid. A laptop, Windows, FTDI drivers and dll to get the data to the logical com port can generate a good bit of finger pointing when things don't work.

Thanks for those answering my questions on my odd 5400 motors 5600B control box situation. Now I have it working with LVB Tracker and Nova. But the motors stop tracking after a few minutes. First it seems to track fine, with motors turning as Nova instructs. But after a few minutes of activating and turning motors here and there, the motors don't seem to respond to the Nova software to move any more. I have to shut down Nova (getting a cannot write to file error), reboot the computer (otherwise when I go to Nova I get an error msg that the device is already connected? (but no response)), and restart Nova.? Then the motors will seem to track as Nova directs, but only for a few minutes and then motors stop working again.? I cannot tell if it is a computer problem (IBM T41 laptop, Win XP), or LVB (just got), or what? Any clues?? Thanks for the space.
