Figure 7: : Magnetic Stripe Format Wiring Connections
Some ABA Track-II Magnetic Stripe (clock and data) compatible control panels require a
card present signal. A circuit can be added external to Pyramid Series Proximity readers to
emulate this signal. Figure 8: provides an example of a circuit diagram using a 47 µF
capacitor and two 1N4148 diodes, illustrating how a card present signal can be emulated.
