What is the easiest way to connect a PNP (current sinking) encoder to a counter-timer? I need to trigger some electronics using a PNP encoder, and it appears the 6612 counter-timer only accepts NPN (line driver) inputs. Is there an easy way to do this? I see several references that some NI cards can be configured for both PNP and NPN, but there is very little information on which ones and on the 6612.
