Anyone having issues with DSQC 377B encoder boards?  
We have three that are suspect, they are brand new units that came straight out of the box. We used the same wiring as all previous versions but we get no LED’s on the units. We think that the units may have some reverse soldered connections but are not sure. Any thoughts appreciated.

Thanks,
