The HSDIO instrument driver functions usage on PXI 6534 module.

[Loka Prakash]

Hi All, I tried running the HSDIO APIs on PXI 6534 Digital Module (with CVI - 7.1, DAQmx - 8.6 and HSDIO - 1.5.2) with no success.I got the following error on execution of those HSDIO functions:"The resource name (corresponding to 6534) is not assigned to an instrument supported by NI HSDIO" I would like to know, whether there is any way/possibility to execute these HSDIO functions/APIs (version 1.5.2 or more) on 6534 Module successfully? If it is possible, please let me know the way of usage. Thanks in advance.   Regards,Loka Prakash

Hello Loca, The NI-6534 does not utilize the NI-HSDIO driver.  It can be programmed using DAQmx starting with version 7.4 or later, which it appears you have.  What functionaity of the HSDIO driver are you trying to implement? The DAQmx driver provides a wide array of functions.  If you could give us a better idea of what you are attempting to do, I could be of further assistance.

Hi Brian Coalson Thank you for the reply.  Actually I need to develop customized digital waveforms (Serial Peripheral Interface signals) across various channels/lines of the 6541 Digital I/O card.Because of some initial hardware limitaions, It is required for me to try this out on PXI 6534 module. My question is whether the HSDIO functions can be used on PXI 6534 Card directly instead of using the DAQmx driver so that I can migrate to 6541 without major code modifications or not? Thanks and RegardsPrakash

Hello Prakash, Unfortunately, the NI 6541 cannot be used with the DAQmx driver functions. Since these functions are required for programming the NI 6534 card, you will not be able to migrate to a 6541 or other SMC-based devices using the same code. However, you may find that the HSDIO driver calls are similar to the DAQmx functions. Many of these functions are a simple 1-for-1 replacement, and so it may not be as hard as it seems to recreate the application. Hope this helps,
