Appendix C - Pinout Info
P1, P2, and P3 are basically just 3 alternate ways to connect the PS12DC.
![](../__attachments/49643941/pinout.jpg?inst-v=53c3afbe-b679-4ae4-ad8c-e895cddff14e)
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.

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.
