how to acquire data from 2 different PCI cards

[shami81]

HI guys, i am using PCI-4472 and PCI-6025E cards at the same time. The resolution of both cards is different and sampling rate is also different. i need to acquire data from two different sources using these two cards. Please help me resolving this issue. HOw can i acquire the data from these two cards smilutaneously. Kindly when you reply please keep in mind that i am a beginner with LABVIEW and currently using 8.0 version of labview.

Hoping to get a quick response from you guys.

Best regards

You need an RTSI cable between those two card. Activate this RTSI cable between these cards in MAX

For each card you need a separate task.
In software you configure one task to wait on the Start-Trigger of the other task.
Search the LabVIEW examples.

Good luck,

Hello Ehtisam

thank you for your post on the discussion forum.

The best thing to do is to connect the RTSI bus between the two DAQ boards. After doing that you need to configure the bus in the measurement and automation explorer (you can do that in the properties of the devices). The RTSI bus is the grey connector at the back of the PCB; http://digital.ni.com/public.nsf/allkb/A120195AAAA9222A86256C69007C8B27

The best thing to do is to find a example (a lot examples are included with your driver, those can be found with the example finder in the Labview getting started window) and adjust this to your requirerments.

I also found some examples about synchronizing a DSA (your 4472) with a MIO DAQ board on our website; http://digital.ni.com/public.nsf/allkb/A133ED27DF9BCC5986256F2E004BA342

I hope this will help you further. Please let me know if there are any other questions,

Best regards,

Martijn

Thank you guys for such a quick response. Just tell me one thing Do i have to order this RTSI Cable from NI? Is there any other way? Coz it takes a long time for shipment of this cable to Pakistan. Moreover what will be the specification for ordering the cable i mean what would i say is that a cable competible with 6025E card or 4472 card?

Hello Ethisham,

Please find pin information under the following link;

It is not a verry special connector, so it is easy to make if you can get two of those connectors (which are common) and a ribbon cable.

Best regards,
