NI MAX: cDAQ recognized, modules not recognized (NI-9136/NI-9237)

[jpc2000]

Hi all,

I'm not very familiar with NI instrumentation so apologies if this is a dumb question. I am trying to connect my NI-9136 cDAQ with two NI-9237 acquisition modules (strain) with my computer, but NI MAX seems to only recognize the cDAQ. (attached images of system and what I'm seeing on the computer. It's a USB connection from the cable on the middle left)

I've updated the DAQmx driver and all other updates that seemed relevant, I've tried restarting the computer and machine, power cycling the machine, trying other slots and other modules, tried another computer's NI MAX, and even tried another cDAQ (NI-9137), but this is still happening. My goal is to get measurements through LabVIEW. I thought it was possible it was recognizing and not displaying the modules, but when I tried the DAQ Assist on LabVIEW, it didn't recognize any instrumentation that would get measurements, whether I had my load washer plugged in or not.

Appreciate any help!

Hello!

You need to connect the cDAQ to your computer or network using the RJ-45 Ethernet Port 1. You will also need to install the LabVIEW Real-Time module- NI recommends using the same version of all software (for example; Labview 2023, Realtime 2023, DAQmx 23, installed in that order).

When you expand “Remote Systems” in NI MAX, you should see your device. If the status is “Inconsistent IP Settings", you will need to set your computer’s IP address to something on the same subnet as the cDAQ. For instance, if the IP address of the cDAQ is 169.254.1.x Subnet Mask 255.255.255.0, then you need to set your computer’s IP address to 169.254.1.y Subnet Mask 255.255.255.0. When the status is “Connected Running or Safe Mode” you can install your software to the cDAQ.

To install the suggested software set, expand the cDAQ and right click Software >> Add/Remove software. To add the cDAQ to a LabView project, right-click the project root and select New >> Targets and Devices from the shortcut menu to display the "Add Targets and Devices" dialog box. Expand Real-Time compact DAQ and you should see your device. LabView will then scan for your c series modules and add them to your project. I have linked the manual below- I suggest reviewing it as the device has a lot of features. You will find that configuration for LabVIEW Realtime starts on Page 19.

Note: The USB device port is intended for use in device configuration, application deployment, debug, and maintenance.
