Appendix C - Pinout Info

P1, P2, and P3 are basically just 3 alternate ways to connect the PS12DC.

P1 - DB15 connector (top left): Mates to small and large LabJacks, like a U3

P2 - DB37 connector (bottom): Mates to only larger LabJack models, like a U6

P3 - 14 pin header (top right): Can be used to wire the board to any other digital output source, like an Arduino.

P2-BREAKOUT - 16 pin header (bottom): For access to covered-up analog inputs when the PS12DC is connected to a LabJack via P2.

When connected to a LabJack, or other digital output source, the name of the output can be determined by looking at the chart below.

Table C1. Channel output and PSU input based on switch number

Table C2. P2 breakout

Example:  Connect the PS12DC via the 15-pin D-Sub connector on a LabJack U3.  You desire to toggle power to switch S9, so you locate the appropriate connector in-use, which is P1, and then follow the row for S9, which points to CIO1.  This means that changing CIO1 from output-low to output-high will change the S9 terminal from 0V to whatever voltage is connected to VS5 and GND5.  

Detailed pin-out

The detailed pin-out information below is for advanced users.  It may be useful to people making a custom board that mates with the OEM PS12DC, or someone who needs to use the rails VM+ and VM- in addition to a PS12DC that is connected on P2.  Most users need not concern themselves with this section.
