View Full Version : usb causing non detection?

07/18/2010, 07:27 PM
bought a used setup with powerbar, head unit, and temp/level/ph interface.

hooked everything up per the manual and get the message that none of my items are detected. doesn't detect the ph probe, level sensor, or temp sensor.

anyone have this issue before and know how to fix it?


pulled the ph probe out of one usb and put it in another and everything works. however, that doesn't really make much sense to me. anyone know a workaround?

If all is now working it sounds like you plugged the usb cable in wrong way. This shorts out the BUS and zero works.
