  1. I have a LabVIEW program, which when operating with simulated input data is blazing fast during mock-up. As soon as I hooked into a real cDAQ on Windows, however, the update speed fell off to 4 seconds. That's awful slow. I don't really have a whole lot of channels. I have read tasks for Volts of maybe 5 channels, write tasks for both On./Off for maybe 10 channels (simultaneous) and write tasks for 4-20mA of only 5 channels. How may I improve on that? Is it maybe a priority issue in Windows or to do with USB? What? How to improve? Thanks in advance.
  2. Hi, I have contacted NI sales services but it's a great frustration as usual, so I will try to get some support here Basically for a project I need 2 CAN ports and I decided to go with XNET and Compact DAQ. I have 2 solutions I try to choose from: Solution 1 --> One 4-slot chassis with 2 NI-9862 modules (one port per module) Solution 2 --> One 1-slot chassis with 1 NI-9860 module (this module has 2 ports) I am confident that solution 1 will work well since I already had a project in the past with one 4-slot chassis (cDAQ-9174) and one NI-9862 module. But going with solution
  3. Lets pretend I wanted to simulate a solar panel using a cDAQ, a programmable power supply and a light sensor. Id have to measure the voltage from the light sensor and the PSUs current, use those values to find the respective operating point on my light/voltage/current-curve and update the PSUs settings. Lets also say I wanted to do this for multiple systems in parallel, all connected to 1 analog input and 1 analog output module in 1 cDAQ. What would be the best way to achieve the quickest response time? Simply reading and writing single samples seams to be pretty slow (though I can encapsulat
  4. Hello, I've been struggling with this problem for months now... I want to use a cDAQ9171+NI-9234 with an Advantech PC (AIMB-580). I have 3 computers like this and all with the same problem. I plug the USB cDAQ-9171, Windows detect the device and loads the proper driver (cDAQ-9171), it is displayed in MAX but self-test or reset always fails with error. At the same time, NI Devive Loader service hangs up. If I try to restart or stop this service it cannot complete the operation, the only way to finish this operation is to unplug the usb cable from the PC, then the service restarts correctly.
  5. I am designing a new project and I need to know if I can get away with purchasing 2 9181 chassis instead of one 9188 chassis. I will be using a 9213 for thermocouple readings and a 9208 for 4-20mA current readings. The signals dont nee to be syncronized and will only have to read once a minute or so. My question is whether or not I can read the signals from both chassis at the same time through MAX and easily imput into a LabVIEW program. I am currently using a single 9188 to accomplish the same tasks at a different location but am trying to cut costs on the next project. The 9184
  6. I am working on a project with requirement of measuring current. The system includes both the AC current transducer CR4211-15 (Input 0/15AAC, Output 0/10VDC) and a Fluke i5S (Input 0.01/5AAC, Output 400mV/A). I use cDAQ9184 with NI-9205. I tested with a light and using MAX to monitor the signal but the signal really noise from the AC transducer and clamp. Please take a look at the pics I attached which is the screenshot from MAX. I hope anyone with exp can give me a help. Thank you! Thang Nguyen
  7. For years I have successfully used the Icron USB Ranger 2204 Cat 5 Extender with both cDAQ and SCXI. But now I have one very annoying issue. I only recently purchased some NI 9237 units for my pressure transucers. Those, and only those, modules don't seem to like being polled over the USB-to-Cat5 extenders which I have in both of my test cells. I have timing issues. Not with all of them all of the time. But with all of them some of the time and with some of them all of the time. I get that pop-up message that says not all of my channels have been read. Increasing the timeout even to ridiculou
  8. I'm needing two c-series Modules for the CompactDAQ. They are a GPS module and an accelerometer module. I know that S.E.A. sell a GPS c series module, but it is only compatible with cRIO, not cDAQ, obviously with the different interfaces. Does anyone know of any companies that sell GPS and accelerometer modules for the cDAQ? Thanks.
