3.4.6 Magnetic Stripe Encoder Circuitry (Option)
Figure 3-8 shows the Magnetic Strip Encoder elements, consisting of the board,
Read/Write heads and associated cables. The Encoder Board is a purchased part that
Eltron Card neither designs nor assembles. Note that the USB and Encoder Boards use
the same CPU Board connector. With both options installed, the Encoder Board
connector attaches to an identical USB Board connector that feeds through the required
signals.
