This installation note is for Continental-Girbau washers without a serial daughter board (typically on washers manufactured before 2015). The reader operates in pulse mode, emulating a coin-drop.
Use the LaundroPortal to set pricing. If using multi-vend pricing, ensure that the Minimum and Maximum settings correspond exactly to the absolute minimum and absolute maximum price vend cycle price that could be attained on the machine (including profit-plus options). If using using a single price for all cycles, it's recommended to set the vend price to 25cents on the machine. This way the reader simply provides a single pulse to the machine to start it (but deducts the full cycle cost from the card)
