FCUSB issues

Post by Helimadness » Wed Sep 04, 2024 10:05 am

I haven't used my FCUSB for a few years and attempted to use it on my Moonlight focuser. I had no movement. Pin out checked 5v one direction and less than .10v the other direction. I assume it should put out 5v both directions. My Moonlight hand control works fine and puts out 9v both ddirections.I also read you make a converter box to step up the voltage. My FCUSB is probably not repairable?

Thanks Keith

The FCUSB should put out +5V in one direction and -5V in the other direction, i.e. the polarity of the 5V should reverse. Moonlite made two variations of their pinout so be sure that is correct, see three paragraphs down on this webpage: http://store.shoestringastronomy.com/products_fc.htm.

Yes, I can usually repair the FCUSB. Send an email to doug@shoestringastronomy.com for more information.
