I have a doubt that how can you recognise different kind of notes that a bv20 is accepting and it's value. For every. If I am paying 10 dollars instead of 50 dollar then how can this machine recognise it. Please help me because I want to use this machine in my vending machine.

Hi, Have you tried changing the setting on LOW pulse output. Increase this to 100ms. You can access this with a use of IF17, DA1 or DA2 device and ITL validator manager or its equivalent , or Configuration by Cards. You can find this in Alibaba.

Please us know if this work.


Hi all, is there someone still working on the BV20 valitator? I am facing issues with the mechanical connections and the code design.

I upload the last code probe, but still doesn´t work.

Does anybody can help me?

Best regards.
