Note These calculations are intended to approximate the maximum power
requirements for an NI sbRIO device system. For a more accurate estimate of the
power consumption of a specific application, NI recommends that you directly
measure a board running the application in an environment representative of the
intended use case.
Configuring the sbRIO-9637
You can connect the sbRIO-9637 to a host computer or network and configure the startup
options using the RJ-45 Gigabit Ethernet port.
Tip Refer to the NI sbRIO-9637 Getting Started Guide on ni.com/manuals for basic
configuration instructions and information about connecting to a host computer
using the RJ-45 Gigabit Ethernet port.

The SD specification allows 200 mA maximum current draw for an SD card. If your SD card does
not specify maximum current draw, assume 200 mA.
