Error code 56 upon attempt to update PXI system to NIDAQmx 7.5

[Tim_Maddux]

I am trying to update a PXI machine (chassis 1052, PXI controller 8187) to NIDAQmx 7.5. I'm using the "Install Software..." button in MAX, and choosing to reinstall NIDAQmx. Upon starting, it goes to the "rebooting into install mode" dialog, no progress on the progress bar, eventually a hang and a beep from my windows machine, followed by a dialog box reporting "error code 56."

Hi Tim,

Are you communicating over a crossover cable? Here is a quote from this KB which lists fieldpoint but is actually general to any ethernet communication:

When using a crossover cable ensure to remove the DNS server IP address from the controller network settings. If there is an IP address listed as the DNS server other than 0.0.0.0 or blank, installing software will timeout due to searching for that DNS server. This will then result in the error code 56. Since you are connected over a crossover cable that DNS server does not exist.

If you are not using a crossover cable, there must be some other reason for the timeout. Are both devices configured with static IP addresses? Could there be another machine with the same IP?

Using a crossover cable instead of the LAN has fixed the problem.

Great! Good luck with the rest of your app.
