The host computer communicates with the device
over a standard Ethernet
connection. If the host computer is on a network, you must configure
the device
on the same subnet as the host computer. If neither the host
computer nor the device is connected to a network, you can connect the
two directly using a crossover cable.
If you want to use the device
on a subnet other than the one the host
computer is on, first connect the device on the same subnet as the host
computer. Use DHCP to assign an IP address or reassign a static IP address
for the subnet where you want it to be and physically move it to the other
subnet. Refer to the
Measurement & Automation Explorer Help
for more
information about configuring the device in Measurement & Automation
Explorer (MAX).
Powering the NI sbRIO Device
The NI sbRIO device requires a power supply connected to J3.
The supply voltage and current must meet the specifications in the
section of this document, but the actual power requirement
depends on how the device is physically configured, programmed, and
used. To determine the power requirement of your application, you must
measure the power consumption during execution, and add 20% to your
estimates to account for transient and startup conditions.
Note
Select a high-quality power supply with less than 20 mV ripple. The NI sbRIO
device has some internal power-supply filtering on the positive side, but a low-quality
power supply can inject noise into the ground path, which is unfiltered.
Four elements of the NI sbRIO device can require power: NI sbRIO internal
operation, including integrated analog and digital I/O; 3.3 V DIO; 5 V
output; and board-only C Series modules installed on the device. Refer to
the
section for formulas and examples for calculating
power requirements for different configurations and application types.
Complete the following steps to connect a power supply to the device.
Refer to Figure 13 for an illustration of the power supply connection.
