IEEE 488 USB

[Abilene]

Hi

i have developed code to control and receive data from an instrument. We connect to the instrument by ieee488 Pci card.

is it possible to substitute the PCI card for one of the NI USB IEEE controllers?  Probably a silly question, does the NI driver show the USB controller as a normal IEEE communications device or do I need to rewrite to look for a USB port and send commanods to the port.

thanks

The change to a USB controller is absolutely transparent.

Hi Dennis

Thanks for the response. This is what I was hoping (praying) for... I was worried that I'd have to rewrite our code to send and receive commands via USB, a bit of a  nightmare. I really hope that it is transparent and the NI drivers simply allow the same code to work with the IEEE-488-USB device.

Thanks
