L70 Bill Acceptor

we're having a problem about it, it is a L70 bill acceptor which accepts philippine bills our problem is when we connect it in our system, we couldn't see the data and pulses of the bills we inserted in the bill acceptor.

Our project is about a payment machine which accepts coins and bills and after every transaction it should sends a message to the payee to confirm that his/her payment transaction is successful.

i hope you could help us, we only have limited time left the deadliest deadline is already on september, if we cant submit it then we cant graduate i college, and extend again

hope to hear suggestions soon
