I have a systwem that I set up that uses 2 paddle wheels npn devices and an encoder card. I have a digital meter hooked up that correctly counts the pulses. However the encoder card is another issue. It reads too many pulses. I have my shielding grounded at both ends, if I only use one end the noise is worse(the counts grow even larger). Any advice on how to eliminate noise as a problem? I still wonder if I'm having a shielding problem or something else. I would like to eliminate incorrect shielding as a problem.
The cable has 4 pair that are individually shielded along with a shielded jacket. Right now I have the jacket grounded at both ends and the other 2 pair grounded at one end. I've tried a couple different scenarios and its not working.
Thanks
