There are3 programmers for the Coinco Bill validators. Depending on which model you have determines which programmer you need. I?ve been upgrading the Coinco?s with about a 1 day turn around. The problem I?ve found with most of the Coinco validators is they need to be rebuilt before they can be upgraded, as they are just about worn out. The Coinco?s only last about 18-24 months in a heavily used
changer/ACW before they need to be rebuilt. I?ve been sending out my loaner Mag-52 to those who don?t have a spare so there
changer/ACW won?t be shut down completely while there validator is in for upgrade. My Mars programmer is still making the rounds across the US, for those who want to do the upgrades themselves.
