Pin out – auxiliary connector
The pin out for the board's 40-pin on-board auxiliary connector (labeled
is identified by a beveled edge on the board silkscreen.
FIRSTPORTC Bit 5 (Start Trigger In/Ext Clock)
FIRSTPORTC Bit 6 (A/D Stop Trigger In)
FIRSTPORTC Bit 7 (A/D Pacer Gate)
* Pin 1 and pin 3 have 10 K pull-up resistors installed.
Use pin 38 for analog output return
When using the analog output pins D/A OUT 0 (pin 39) and D/A OUT 1 (pin 40), use D/A GND only (pin 38)
for the return.

Cabling

For signal connections and termination, you can use the CIO-MINI40 screw terminal board and C40FF-x cable.
For connections to 37-pin screw terminal boards, you can use the C40-37F-x cable.
