m-pod for Biopac MP36 (and MP35) connects directly into the I/O Port connector on the back.
Please note that the STP100C module also has a similar DB25 connector but it is not pin-compatible with the one on the MP35 and MP36. Connecting “m-pod for Biopac MP36” to the STP100C will not work.
Setting up BSL to work with m-pod is straightforward:
1.
Click on the MP36 (or MP35) menu and choose Set Up Channels….
2.
The “Input channels setup” dialog appears. Click on the Digital tab.
3.
Enable all checkboxes for each of the Acquire, Plot, and Value columns.
4.
Optionally, you can also rename the labels.
Close the “Input channels setup” dialog and click on “Start”.
The channel number in the table is as seen in the BSL package. Ground is on DB25 pins 5 and 6:

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.
