How can I configure and control a non-plug and play VXI card using the NI-controller (NI-VXI/NI-VISA software)?

Defining the slot, logical address and sending data across the card bus are the main operations I would like to perform. The non plug&play card is a VXI send & receive slave card. Low-level programming is probably required. Has anyone tried this before? If so I would be so grateful if you could share your experiences or refer me to someone who has.

Thank you for your time and help,

VXI cards are, by specification, plug and play, so I'm not exactly sure what you mean by a "non plug&play card." I'm guessing that the card is effectively a VME card. In this case, you can just add the VME device in the proper configuration utility. Here is a link to a document on our website about configuring VME cards (http://ni.com/support/vxi/vmeinfo.pdf).

You should easily be able set the slot, pseudo Logical Address and memory space. Once configured, you should be able to write to registers using NI-VISA commands (viIn, viOut, and viMove). These high level commands are included in the highreg.c example which shipped with your NI-VISA software (installed in vxipnp directory).

I hope this helps.
