The $5 bill software upgrade is now available for the 115 vac Mars validators with a programmer. I upgraded a number of validators without any problems Friday. I should have the 24 vac software within the next week. The problem I see with the inbay coin boxes is every coin box manufacture has a different power plug supplying power to the validator so the programmer plugs will not connect to the coin box power supply. I currently have a list of those who wish to use this programmer. The 110 vac programmer is out now to one of our Forum regulars.
