Electric coin mech + Mini-pac = fried chips?

[stevenup7002]

Hi everyone, this is my first post here so bear with me.

Yesterday I was talking in the chatroom about my new electronic coin mechanism, I wanted to get it working  but I got it working after a while. But now I'm afraid to connect it to my Mini-pac, it says its supposed to send out a 12v pulse through the coin 1 pin. Will this damage my mini-pac. On the ultimarc website it says somthing about a zener diode, but there is no mention of a zener diode on my instructions sheet.

Its a weiya Hi-07cs.

Thanks for reading
-Steven

Hey everyone, just to let you know, I got it working, heres how:

I got an LED from an old cereal box prize and got plugged the negative side into the coin mech output and the positive into the minipac, then I set the coin mech to NC  (!!Super Important!!) , it works like a charm!
