RPI output connections
Feed the output pairs in through the bottom of the RPI and route the pairs to the output connectors.
The following figure shows how to route the output pairs. If you use one pair to power a base
station, connect the power pair to -PWR(1) and +PWR(1). If you use two pairs to power a base
station, connect one pair to -PWR(1) and +PWR(1), and the second pair to -PWR(2) and
+PWR(2).

Caution: Ensure both pairs have the same polarity.
If you connect two power pairs with opposite polarities, you can damage the base station
and RPI.
