MK3201BV
The way of Using the bill validator machine MK 3201BV

We had the need to reuse the bill validator MK3201BV
We tried to install it on Japanese PachiSlot for game machine(Amusement spec under No.8 of Japanese law)
We did not have the instructions of this Bill Validator machine.

We examined this machine of the signal waveform, while introducing 1000yen bill.

The control board of the game machine does not operate correctly in this state.
So we designed the electronic circuit and a microcomputer program to create a signal that can react the control board.
We haveconsideredtwo types ofcircuit.
Microcomputer programs are common in both type
Type1

Type2

Outline of the Microcomputer programs

Program description of the 1.4.5 logic has inverted because this circuit uses the transistor array in order to drive the relay.

ALEX Bill Validator
FX3801= BILL VALIDATOR-A
FX3201= BILL VALIDATOR-B

Open the F3801(BILL VALIDATOR-A)

We can find the same connecter]

Change the connecter each other

Bind the wire to be lereased

Shut the F3801(BILL VALIDATOR-A)

Keep the FX3201(BILL VALIDATOR-B)
