Why Can't the NI-7935R Communicate with the
Network?

1.

Connect cables from your device to the host computer.
a)

If you are using the USB port, use a USB cable to connect the NI-7935R USB
device port to a host computer.

The USB driver creates a virtual network interface and assigns an IP address to the
NI-7935R in the format of 172.22.11.

If you cannot power down the NI-7935R, use the System Configuration application programming
interface (API) to disable power to the adapter module.
