Multi-coin Acceptor Debugged

The model 623 multi coin acceptor was made available early this year. It was welcome addition to e-Gizmo product line.  In fact, the first few dozen was immediately sold out in just a short while after availability was announced.

Things did not went very well for the first few dozens though. To our horror, we realized that the manufacturer had programmed to device for us to output pulses that does not correspond to the amount of the coin inserted. Worse, too many pulses were being generated: the Five peso coin churns out 40 pulses; the ten peso coin generates 80 pulses! Even at its fastest pulse rate setting, one will have to wait 40 seconds before the acceptor finishes the pulse transfer of a 10 peso coin.

We immediately stopped selling our remaining stock and contacted our supplier for a resolution to this problem. Even with this fault,  people who had brought this acceptor were not willing to return back the units (for various reasons), so we invented some workaround to make the unit usable even while it is crippled with this problem.

Now the good news is, the manufacturer promptly corrected this problem, and starting this April, only the multi coin acceptor with the correct output pulses will be sold @ e-Gizmo.



The new Model 623 coin acceptor is pre- programmed to accept Philippine Coin in 1 peso, 5 pesos, and 10 pesos denomination. The coin acceptor will now output pulses corresponding to the coin amount as follows:

1 Peso = 1 pulse

5 Pesos = 5 pulses

10 Pesos = 10 pulses


The coin acceptor can be used straight out of the box without the need for further user programming. But to improve its coin recognition ability, you may want to ‘train’ the 623. How you will do this is described in detail in the accompanying manual. You will need a lot of coin samples to perform the ‘training’.
