Type of 68 pin connector on PCI 6221 board?

[Eovein]

Please tell the type of 68 pin small connector on PCI-6221 DAQ board. To it can be connected NI`s "SHC68-68-EPM" cable, but I need to make self made cable to connect my device to DAQ board, but I can't find the type of 68pin connector

Eovein,

all M-Series products use a 68pin VHDCI (Very High density Micro Centronics)- Connector - have a look into the specifications manuals p. 9 (http://www.ni.com/pdf/manuals/371290d.pdf).
Thought, connectors and backshell kits should be available be several electronic suppliers, but be careful, when you design a cable. The SHC68-68-EPM (btw: EPM stands for Enhanced Performance M- Series) is especially designed for this boards in respect of impedance, shielding, twisting and proper connector resistance ....etc. to carry the signals properly. Have a look at this great tutorial "Field wiring and noise considerations for analog signals": https://www.ni.com/en/shop/data-acquisition/measurement-fundamentals/field-wiring-and-noise-consider...

Hope this helps. Good luck,

Stefan

The PCI-6221 is also available with a 37-pin DSUB connector (https://www.ni.com/en-us/support/model.pci-6221.html). Making a cable for this connector may be easier.
