How can I re-establish communication with pxi chassis after power off then back on?

Hello,

I need to know how to re-establish communication with my PXI chassis after powering it off then back on without having to reboot the computer. I have a PXI-1002 chassis connected to a PC using MXI-3 cable connecting PCI to PXI-8330 cards. I have one module installed in the chassis which is a PXI-6514. My PC is running CentOS 5.7 with Linux kernel 2.6.18-274.17.1.el5.

I have a program written in C that communicates with the PXI-6514 board. After powering off the chassis and then turning it back on I can no longer communicate with the board. An indication of the problem appears with the lights on the PXI-8330 board. The green lights on the PWR and LINK are on and an amber light stays on for the TX. The amber light is normally off. The only way I have found to reset the chassis and restore communication is to reboot the computer. Is there a command I can add to my program that will re-establish communication without having to reboot?

nilsdev returns:

NI PXI-6514: "Dev1"

Though I think it just gets this info from a config file.

Any help is appreciated.

Thanks,

Greg

The MXI-3 system is a PCI to PCI bridge, so the PXI devices are like PCI cards in your computer. I don't think that there is a way to do what you want to do, sorry.

Thanks for the reply. I had pretty much come to that conclusion myself I was just hoping that I had missed something.
