I am trying to syncronize Two M series PXI 6281 boards in the PXI 1042 chasis using the Real time controller PXI8187, I could not find any examples which i could run.
I quite new to sync multiple devices.mOst of the example mentions using RTSI bus.

Any help would be helpful

Hello,

The RTSI cable and the backpane of the real time controller are esentially the same thing, even the driver sees them both as the same thing. So any example that you found for synchronizing these two boards should also work with your controller. By the way, what are you trying to synchronize (AI in both boards, AI in one board with DO in the other board, etc?) Also what program and version are you using (LabVIEW 7.1, CVI, etc.)

Please let me know about this and if you have any additional questions.

Thanks,

LA

Hello,
I got this working with one of the examples. Iam using two M series boards 6281 and sync Analog Inputs

Thanks

I am attempting to do essentialy the same thing.  I would like to synchronize two 6281 that are running on a PXI-1036.

I am very new to LabVIEW, and very green at creating vi's.  If someone could give me some baby-steps to getting the two DAQ's syncrhronized to collect AI (differential) from each DAQ, that would be great!

Thanks!

Hello  NI_LV_82_User,

It is generally better to post a new question to a new discussion forum rather than adding it to the end of an existing one. You are more likely to find users who can provide good advice by posting a new forum. That being said, there are several resources online that I think you may find useful. Specifically, there is a tutorial called "M Series Synchronization with LabVIEW and NI-DAQmx" online here. In addition there are several example programs that demonstrate how to synchronize M Series devices.

There are also several resources that you may want to check out to get you started programming with LabVIEW and DAQ. The "Getting Started with NI-DAQmx" series offers several tutorials and example programs to help. You can find the main page for this series here.
