We have a RaceAmerica Top 5 position scoreboard with 24in tall digits model 64835A. We recently moved the scoreboard to a new location on the track and one of the interconnect connectors between position got crushed and some wires ripped out. I can trace the wires back to their connections on the circuit board but since all the wires have a black jacket, I am not sure how to connect the wires to the appropriate pins in the connector.

Is there a drawing of the pinouts available for these connectors?

I found a diagram of the connector with pin numbers if that is of help.

The 16-conductor connectors located at the top and/or bottom of each 2-digit and 3-digit Top 5 and Top 10 position enclosure have the same pinout definitions and not all pins are populated in the connector. Connectors allow the wiring between position enclosures to connect the rightmost digit above to the leftmost digit below using the following pinouts (in red):


Pin 1 = BATIN/BATOUT (on circuit board)
Pin 3 = enclosure ground
Pin 7 = VCCIN/VCCOUT (on circuit board)
Pin 8 = CLKIN/CLKOUT (on circuit board)
Pin 9 = DATIN/DATOUT (on circuit board)
Pin 10 = STBIN/STBOUT (on circuit board)
Pin 16 = GNDIN/GNDOUT (on circuit board)

Be careful not to cross connect BAT and VCC to any other active pin as this will damage components and require more than a cable repair.

You might want to double check the wiring for pins 1, 3, 7, and 16 to insure all power sources are connected correctly before powering up the scoreboard. Pin 3 is physically a short jumper wire between each male or female connector and the enclosure (frame ground). All other connected wires should show continuity from each pin to where the wire connects to the circuit board with the appropriate xxIN/xxOUT label.
