Configure the machine settings so the machine start's from the 1 Pulse it gets from the Card Reader
These card readers are emulating a coin being inserted into the machine, so when a laundry card is tapped to the reader, the card reader ONLY SENDS 1 PULSE to the machine to trigger it to start.
For Card Only installs, Coin 1's input is set to $0.25 by default, to work with the coin drop correctly.
For Hybrid Installs, Coin 2's input may be set to $0.25, or $1 by default.
Which ever Coin input you have connected the card reader to, you'll need to go into the machine's programming menu, and change the Value of that Coin Input to equal the full Vend Price of the machine.
This will ensure that 1 tap of a laundry card satisfies the full vend price of the machine so it starts from 1 tap of a card.
Note: For Hybrid installs
Be sure you are ONLY changing the coin value of the Coin input that the card reader is connected to.
You want the Coin input that the coin drop is connected to, to remain at $0.25, so quarters only take off $0.25 from the machine's vend price
If you try to pay for the machine, and the price goes down, but doesn't go all the way to zero (maybe only $0.25, or $1 is being deducted from the vend price being displayed on the machine), then you'll know the Coin Value setting is not set correctly, as it needs to equal the machine's full vend price.
