Figure 1: Power Terminals VA and VB
Each set of I/O terminals contains 8 pins. Those are divided into 4 pairs, with each pair are
types: “direct pin” (P) and “driver output” (D). These are labeled in terminal:direct|driver
format. For example: 2:3D, which indicates the driver output third I/O on the second terminal.
When looking into the I/O terminals, they are always in order Driver|Pin when looking from left
to right.

P pins connect directly to the associated interface pin. These can be used for low-current
outputs, inputs, 1-wire sensors, etc. just as if the wiring were being directly connected to the
interface microcontroller at its pin/port location. When used as an output, the current
limitations for that particular interface pin must be followed (e.g. 10 mA).
