Installation

1. Before proceeding, you should assign numbers to each of the machines in the laundry room/building. It is highly recommended that you place number labels on each washer and dryer machine.

   See article: Reader DIP Switch settings
   
   
3. Turn machine power OFF!
   
   
4. Cut the coin-drop cable harness, leaving the connection to the control board (on connector H4)
   
   
5. Splice the cable harness wires to the coin-drop harness from Step 4 above as follows
   

   
   

   Reader harness	Coin-drop harness	H4 pin number
   RED	RED	5
   GREEN	GREEN	2
   WHITE	BLUE	6

   
   
6. Connect the 120Vac side of the power supply, either to an available wall outlet, or splice the power supply directly to the machine, using an appropriate high-voltage connection inside the machine.

   When connecting to the machine directly, you'll be cutting off the AC prong, and splicing these wires directly to the machine (we recommend consulting the manufacturer, or an electrician, to confirm this type of connection).

   
   
7. Proceed to secure the reader to the machine and then Activate the card reader with the Activation Card:
   
   
   
   

Vend price control

The reader sends one pulse to the control. Set the washer to start from just one pulse by setting the vend price on the washer to $0.01 or by setting the value of coin1 to equal vend price (the former is recommended).
