count pulses with pci6601 and bnc2110

[pino1]

Hi,

I am trying to count pulses using a pci-6601 in combination with a bnc2110 connector block. I tried to connect a lolck wave to the 2110 but I dont know to which connector I should connect it. In the measurement and automation explorer I dont see any counts. Also in the measurement and automation explorer I can only choose pfi39 to 11 and I cannot find these on the 2110.  I dont know to which bnc connector pfi39 is connected and it does not say it in the manual.
Any help is greatly appreciated!

You should use a BNC-2121 with counter cards like the PCI-6601. The BNC-2110 is designed for the M Series, E Series and NI 67xx devices.

ear Sir,

Thank you for your post. You should indeed use the BNC 2121. The BNC 2110 us not supported for the counter timer cards.

To know a little bit about the routing from the signals you can compare the pinout positions from the SCB 68 to the positions with the BNC box. Connector layouts can be found under https://www.ni.com/en/support/documentation/supplemental/17/scb-68-and-scb-68a---daq-multifunction-i...

But again the BNC 2110 is not supported for the PCI 6601,

best regards,

Thanks very much for the help!

 It seems the easiest would be to get the bnc2121. However I managad to count the pulses by connecting it to the trigger/counter port on the right and specifying dev2/ctr0. Probably coincidence that these wires are routed correctly.

Now I would like an external clock to control the timing. Could you please tell me what kind of signal I should apply for that?

Best,

You must use a TTL signal. More details for the levels in the specifications of the PCI-6601.
