CABLE CONNECTIONS AND PIN LISTS
The cable connections to the host are J3 on the PCB. Table 2-1 lists the pins and signals for the
9-pin connector, and Table 2-2 lists the pins and signals for the 7-pin connectors.

Back Sensor and Card Present
The back sensor is active low when the card is fully inserted at the back of the unit. If a Card
Present signal is used as with P/N21065114 (See Table 2-1 above), the movement of an encoded
magnetic stripe past the read head generates the signal active low. These two signals are gated to
reduce the dwell time needed before the read-on-withdrawal can be initiated. On P/N 21065117,
Back Sensor is active high.
Track Data
Tracks 1 and 2 data signals are active low when data is read. See Timing below.
