how to connect USB 6259 so that I can generate pulse trains from a counter

[jeongho20000]

Hi,

We've just bought NI USB-6259 BNC. We used to use BNC-2110 which has BNC terminals for trigger and counter so that we can send pulse trains through it to our electrical stimulator.

However, I can't find any BNC terminal for counter output on the new device. Could anyone teach me how to do it?

Thanks,

Jay

Hi, Jay.

Great question.  The following screenshot will give you the Counter/Timer Signal associated with its respective PFI line:

This table can be found in the NI-DAQmx help (NI-DAQmx Device Terminals Help » NI USB-6259 BNC).

To access these PFI lines from one of the user-defined BNC (User 1 and User 2), wire the desired PFI line to the desired User line.  For example, if I wanted to access Counter 0 Out from the User 1 BNC, I would wire the USER 1 pin to the PFI 12 pin.  The USB-6259 BNC specifications manual doesn't give a good description of how to access the User 1 and User 2 BNCs, so I would refer to page 9 of the user manual of the BNC-2110.  It's the same basic concept, just different pin-outs.

Let me know if you need any more information.  I hope you're having an incredible day!
