I just purchased a used Universal Instruments Boardflo conveyor model 5363. It looked like it would be perfect to connect 2 of my Quad 4c machines in line. it came with a SMPI to Smema converter box. I connected the box S1PL and S2PL to what I beleive is S1PL and S2PL on the conveyor and the SMEMA cables to my P&P machines but I cannot get the conveyor to run. There is 1 red LED on the conveyor control board that is on (next to the reset button). If anyone can be of any help I would greatly appreciate it.
