The LED indicator indicates device status, as listed in Table 1. When the device is connected to a USB port, the LED blinks steadily to indicate that the device is initialized and is receiving power from the the LED is not blinking, it may mean that the device is not initialized or the computer is in standby mode.

5 In order for the device to be recognized, the device must be connected to a computer that has NI-DAQmx installed on it. If your device is not blinking, make sure your computer has the latest version of NI-DAQmx installed on it, and the computer is not in standby the NI USB-9263 DeviceCautionA high voltage screw terminal backshell must be installed when using hazardous voltages (> Vpk, 60 VDC).NoteTable 2 illustrates the accessories available from for use with the NI USB-9263 .

AccessoriesAccessoryAccessory DescriptionNI 993210-position strain relief and high-voltage connectorNI 993610 screw-terminal plugs National Instruments Corporation7NI USB-9263 User Guide and SpecificationsThe NI USB-9263 has a 10-terminal, detachable screw-terminal connector that provides connections for four analog output channels.

6 Each channel has a terminal to which you can connect the positive lead of a voltage signal, AO. The NI USB-9263 also has common terminals, COM, that are internally connected to the isolated ground reference of the module. Refer to Table 3 for the terminal assignments for each channel. Wiring for High-Vibration ApplicationsNational Instruments recommends using ferrules for terminating wires to the detachable screw-terminal connector or using the NI 9932 backshell kit to protect the connections when you use the NI USB-9263 in high-vibration applications.

Connect the ground of the load to a COM terminal. Figure 8. Connecting a Load to the NI USB-9263NI USB-9263 CircuitryThe NI USB-9263 channels share a common ground that is isolated from the other modules in the system.

7 Each channel has a digital-to-analog converter (DAC) that produces a voltage signal. By default, NI-DAQmx software allows you to write scaled values to the analog output channels. Refer to your software documentation for more channel also has overvoltage and short-circuit protection. For more information about the overvoltage and short-circuit protection, refer to the Specifications 9. Output Circuitry for One ChannelWhen the module powers on, the output channel drives the power-on voltage. Refer to the Specifications section for more information about power-on voltage.
