Hi,
I own a car wash and have been slowly learning the electronics/electricity aspects of repair and maintenance. I've been able to muddle my way through just about everything I've run into so far, but I've run into a brick wall with an improvement that I've been trying to complete. I'm hoping to find out if what I'm thinking about is possible.
I have an Auto Cashier that accepts payment for automatic car washes. The cashier has four price/wash options that are selected by pushing the appropriate button. My understanding of the way the cashier works is that for the first wash pressing the corresponding button generates 5 electronic pulses which tells the unit how much $$ to collect and which wash to provide. The second wash/button generates 6 pulses, third button 7 pulses and fourth button 8 pulses. The button and resulting pulses correspond to the cost and wash package.
I purchased a credit card reader that I successfully installed two other places in my wash. One I installed on a self-serve meter box and the other I installed on a token machine. The credit card reader comes with an "isolation interface adapter" which allowed me to tap into the coin mechanism on the meter box and the $5 bill wire on the token machine bill validator. So, the pulses generated by the coin mechanism or the bill validator tell the card reader how much $$ to charge the credit card.
Since the auto cashier operates on 5, 6, 7 or 8 pulses I would only be able to charge $5, $6, $7 or $8 for the corresponding washes (or increments of those amounts ($10, $12, $14, $16, etc.).
My question: Is there a way to convert the pulses that the auto cashier generates to a different number of pulses to the credit card reader? For example, 5 pulses on the auto cashier would equal 6 pulses to the credit card reader, 6 pulses to the auto cashier would equal 8 pulses to the credit card reader, etc. I would need something that could be easily changed as prices change. I think it is possible, but I'm not sure where to start.
Any thoughts would be greatly appreciated.
