Encoder connection

I have an HTL encoder with pin connection as this:




and a Simovert MC with an SBP card eith connections as this:




Where must I connect the C connections of the encoder?
Did anybody use other connections ?

I'd bet C = Zero. (zero high or low).

Mike is correct (as usual)

C goes to 'zero/fine+' and /C goes to 'zero/fine-'

Good luck,
