PC6 Encoder to Counter Interface Board
PC6 Product Description
The PC6 decodes the quadrature outputs of an incremental shaft encoder to drive standard up/down counters. The PC6-U, up count / down count version, can be connected to the inputs of common counters such as a 74193 or 40193. The PC6-C, clock and direction version, can connect directly to the counters such as 4516 or 74169. Note: The encoder interface IC used in this product can be purchased separately (see the LFLS7183 & LFLS7184 pages).

Index (Pin 2)
The index signal is routed unchanged, directly from the encoder.
PC6-U-x, pin 3 (LFLS7183).
Normally high, low-true. Down counts are enabled only when B leads A (clockwise rotation). One pulse is generated per encoder cycle using the PC6-U-1 and four pulses are generated using the PC6-U-4. For example, a 500 CPR encoder will produce 500 clocks/rev. using the PC6-U-1 and 2000 clocks/rev. using the PC6-U-4. The external counter should count on the rising (high-going) edge of this output.
PC6-U-x, pin 5 (LFLS7183).
Normally high, low-true. Up counts are enabled only when A leads B (counterclockwise rotation). One pulse is generated per encoder cycle using the PC6-U-1 and four pulses are generated using the PC6-U-4. For example, a 500 CPR encoder will produce 500 clocks/rev. using the PC6-U-1 and 2000 clocks/rev. using the PC6-U-4. The external counter should count on the rising (high-going) edge of this output.
PC6-C-x, pin 3 (LFLS7184)
This output steers the external counter up or down. High = Up (A leads B), Low = Down (B leads A).
PC6-C-x, pin 5 (LFLS7184)
Normally high, low-true. One pulse is generated per encoder cycle using the PC6-C-1 and four pulses are generated using the PC6-C-4. For example, a 500 CPR encoder will produce 500 clocks/rev. using the PC6-C-1 and 2000 clocks/rev. using the PC6-C-4. The external counter should count on the rising (high-going) edge of this output.
Connector
The output connector on the PC6 is TE#640456-5. The mating connector with five 12" wires attached is the CA-C5-W5-NC-1, which uses TE#640442-5 ( see the Cables / Connectors page).
