RJ11 1-Wire Interface
See Figure 8 below for the “Customer” 1-Wire Interface. This is the 1-Wire interface designed to be external to the
board and accessible by the user or “customer”. It provides a place for a DS1402-DR8 Blue Dot to be plugged in
thus allowing customers easy access to make contact with their user tokens for debiting purposes.
