Payrange works in some but not others

[edward]

Good evening,

Does anyone know why Payrange works in USI CB500 drink machines, but not in USI CB300 drink machines?

Is there a way to fix this?

Thank you?

Have you contacted Vendnet to find out if the eprom can be upgraded?

Probably because it's using a basic F80 board.  I doubt that you can even replace an eprom on it.

The CB-500 and CB-300 are not legit model numbers.  The CB-500 can be a 3189 and 3500 and possibly others as well.  The 3500 should work fine but the 3189 won't work with card readers (I don't think payrange would work either in a 3189 but I would love to know if it does).  The CB-300, particularly the older ones, probably won't work either because I think they have the same board as the 3189.  They are cheap coinco boards that weren't designed in a way that allow them to send the proper data through the MDB signal to/from a card reader.  This is what a USI tech told me years ago because my 3189 wouldn't work.

Ok.  Thanks for all the info.
