Powering the sbRIO Device
The sbRIO device requires a power supply connected to J3. The supply
voltage and current must meet the specifications in the Power
Requirements 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 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 sbRIO device can require power: sbRIO internal
operation; 3.3 V DIO; 5 V output; and board-only C Series modules
installed on the device. Refer to the Power Requirements 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.
1. Remove the MINI-COMBICON plug from connector J3 of the
sbRIO-960x. Refer to Figure 4 for the location of J3.
2. Connect the positive lead of the power supply to the V terminal of
the MINI-COMBICON plug.
3. Connect the negative lead of the power supply to the C terminal of
the MINI-COMBICON plug.
4. Re-install the MINI-COMBICON connector in connector J3.
Powering On the sbRIO Device
When you apply power to the sbRIO-960x, the device runs a power-on self
test (POST). During the POST, the Power and Status LEDs turn on. The
Status LED turns off, indicating that the POST is complete. If the LEDs do
not behave in this way when the system powers on, refer to the
Understanding LED Indications section.
You can configure the device to launch an embedded stand-alone
LabVIEW RT application each time it is booted. Refer to the Running a
Stand-Alone Real-Time Application (RT Module) topic of the LabVIEW
Help for more information.
