LEGACY WIRING
Sometimes legacy wiring (unshielded and straight through, rather than shielded
twisted pair, often 22-6) results in slower connections and dropped packets between
the Openpath Reader and SDC. To remedy this, you can switch GND and VIN with +B
and -A connections on the SDC and readers to ensure the data pair (+B and -A) are
using the alternate pair of legacy wires.
