Coin acceptor --> alberichi --> comestero

Hi. I'm planning to connect both versions of coin acceptors to my arduino mega board. As far as know only difference is inhibit and coin line pinout.

Question: - do i need to set some pull ups to the lines - i think that i have to use inhibit line but am not sure how.

Main idea is to read out each coin ( print it out to lcd ) and if the amount is 2 euros, open the door.

Am following this tutorial and i hope that am on right track.

Btw. What is with inhibit line. This should set 5v to lockout the mechanism. Can i connect it directly to arduino ?

Regards !
