BNC-2090A: Use BNC connectors + front 68 pin connector + spring terminals simultaneously?

[Fazevedo]

Hi all,

I've bought a PCIe-6341 DAQ board, a BNC-2090A block connector and 2 SH68-68-D1 68-pin cables. My objective is to use the BNC-2090A to read in simultaneous signals coming from some BNC connectors (among the AI-0 to AI-15 connectors), the frontal 68 pin connector and from the spring terminals block. The final goal is to output all signals from the rear 68-pin connector of the BNC-2090A to the PCIe-6341 DAQ board. Is it ok to do that? Sorry if this is a basic question but I have just started using such systems.

Best regards.

Hello,

The first place to get some help would be the NI Example Finder. You can access this from the main LabVIEW startup menu » Help » Find Examples. If you search for synchronization analog input you can find an example to show you how to implement that.

Since you mentioned you were new to these systems, I might suggest checking out the Getting Started with NI-DAQmx: Main Page. I think it would be a great reference to help you get started programing in LabVIEW with DAQmx!

Here are a few further reads for more information regarding synchronization:

This white paper that explains the concepts of synchronization and how to do it with NI software and hardware. I think this would provide you an in depth look on configurations, considerations and design.

In the last section of this white paper, SC Express and X Series,  explains some considerations when attempting to synchronize on X series devices.

Cheers,

Mike P.

Thank you very much for the info. I just wanted to know whether it would work. By knowing it will, now I will invest time on learning how to make it function. I really appreciate the feedback.

Best.

I couldn't achieve what I needed. My main question now is: Is it possible to configure the BNC-2090a in a way that when 2 cables are connected to the frontal and rear 68-pin socket each, it does NOT work as a pass-through? My final goal is to get the signal of 4 pins (2 pairs signal + ground) of the 68-cable sending the inputs and output it to the DAQ-board. Of course I could cut the 68-pin cable and solder BNC connectors to the 4 specific wires and connect them to two AI channels in the BNC-2090a but I was looking for sth more "elegant".  

Best.

Internal connections between pins is possible, but it is dependent on the type of I/O. But I think it would easiest to get a BNC to connector block converter.
