yes, we have some connected in count down, basically set up so it sends pulses to timer like a coin mech or bill acceptor would. I don't think there is a way to keep the different pricing between vac and fragrance/shampoo in count-up mode, but we were planning to do count down on vacs anyways. can send info later, but basically used a ac/dc converter and a low logic level relay to send nayax quarter pulses to timer.
