Appendix C - Pinout Info

Summary

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.

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.

Can I still use the counters/timers with this board installed on the DB37?

Connecting to a DB37 on the U6/UE9/T7 means you are using P2 on the PS12DC, and that connector uses all 8 FIO lines.  On the U6 can you put the timers/counters on EIO, so that works.  On the T7 some DIO-EF (timers/counters) appears on EIO/CIO.  On the UE9, the timers/counters only appear on FIO.  Can you put the PS12DC on the DB15 instead?  If you have to put the PS12DC on the DB37, do you have to use all 12 channels, or can you leave the first few unused in which case you might be able to use the FIO0-FIO3 terminals on the LabJack itself as timers/counters.
