connect SCXI-1000 w/ 1140 module & 1301 end to DIO-32 card

[gth724k]

Hello, I want to connect my SCXI-1000 box w/ 1140 A/D-module & 1301 connector block to my DIO-32 card.When I go to MAX (4.0), I can install a new device for the DIO-32, tell it it is 1000 w/ 1140, and it all shows it. But when I try to do "test panel", it tells me that the slots are empty.When I plug the SXCI into a 6259 analog card, I can read out signals via "Test Panel", but when I try to set up the SCXI as a new device, it won't work either.I attached some screenshots to show the different scenarios.How can I get this going?Thanks.Matt Hoepfer

Hi Matt,

 

Thanks for the screenshots.

There are a couple of things here:

1. You cannot connect your 1140 module to your DIO-32 since there is no digitizer in the system. The 1140 is analog sampling hold which will keep current samples until the digitizer convert the signals (your 6259 in this case).

2. The second part is why is this SCXI module not working with your 6259. There are a couple of things to try:

            a) Try the module in other slot.

            b) Are any of the connector pins bended?

            c) Is the DAQ card working by itself?

 

Let me know the results and we can go from there,

Thanks,

Thank for the fast response,

The SCXI-1000 is only a chassis and it is the one routing signals and multiplexing everything. However you cannot connect this chassis to any DAQ card if there are no modules. Therefore, the module is the one connected to the card. Therefore, no you cannot connect the DIO card directly to any analog module.

 

About having four 1140 and all of them read by the 6259 is perfectly possible. Just connect it to one and configure software like page 13 step 9 said: <a href="http://www.ni.com/pdf/manuals/373236f.pdf" target="_blank">http://www.ni.com/pdf/manuals/373236f.pdf</a>

Then, you can run test panels on the modules and not anymore on the card.

Make sure you do all this in DAQmx as you are doing it on screenshot TestSCXI1000.jpg

You do not need to do anything in Traditional.

Finally, you should get positive results in screenshot TestPanelSCXI1140.jpg making sure it?s on the correct slot number. Try auto detect modules function (step 10 of same manual).

&nbsp;

Good luck,

Hello again Matt,

&nbsp;

There has to be one little piece that connects between your SCXI and your 6259. The 1349 Looks like this: <a href="http://sine.ni.com/nips/cds/view/p/lang/en/nid/1627" target="_blank">http://sine.ni.com/nips/cds/view/p/lang/en/nid/1627</a>

This one enables to communicate with the entire chassis.

&nbsp;

Even if you have a 6259 with 32 analog inputs, when you connect any card to the SCXI you will only use 1. Then all the Analog inputs of the SCXI are conditioned by each module then multiplexed by the chassis to one single AI from the DAQ card.

&nbsp;

The test panels you will run are directly on the SCXI module (1140 in your case) and you can run these test panels for each of the modules configured under the SCXI chassis under DAQmx.

&nbsp;

There is more information on this link page 3-29 about your specific module:

Let me know how this goes,
