I had the USB port on my LVB go out after a voltage surge that took out my computer. I removed the USB board and put the chip in for serial control. With the DB9 connected to computer with real serial port(not USB/serial converter) the LVB will not always track right. I use for EME and SAT and sometimes it will just idle when it shold be tracking. Are there any port settings that I need to change or any advice when used via serial cable. Also is the USB board available just as single part.
Thanks for any info, 73, Joe KI4TZ

It is probable that the surge got deeper into the the tracker and damaged other components. Lightning has a habit of doing major damage and also stressing other parts. It is probable that the control device has experienced EMP damage that causes it to do strange things. I learned my lesson many years ago when trying to be the hero and fixing some lightning damaged gear. I got everything working, and a week later the equipment was back for additional repairs. Then the next week it was back again. The fix was to replace the equipment or replace all of the solid state devices. Just replacing what is bad today will get the equipment back up for a while, but, it will probably fail again, at an inopportune time. Lightning just stresses the devices too much.

Hi Glenn, No, the tracker works fine with a Serial to USB adaptor, I would just like to eliminate the adaptor. The comport on the laptop may be faulty. I just got it yesterday at the show. That is why I asked it there were any port settings that anyone had used different from the virtual USB ports. Tnx for coming by yesterday, it helped a lot..
