The channel number is as seen in ActiView. The analog (Trig. number) and decimal values are both presented. Ground is on DB37 pin 37. BioSemi’s description of trigger signals might also be useful.

m-pod contains a powerful microprocessor that can reassign any input signal to any output line, and without any significant delay. It can also assign multiple signals to the same output line.
The tables above describe the factory default. If your experiment or lab setup requires different output, Cedrus provides a free utility for configuring your m-pod. After you use it, your configuration is saved to flash memory so that it’s remembered even after you power off m-pod.
