NI USB-9264 User Guide and Specifications
Each channel has a digital-to-analog converter (DAC) that produces a
voltage signal. Each channel also has overvoltage and short-circuit
protection. Refer to the
section for more information about
overvoltage and short-circuit protection. Refer to Figure 9 for an
illustration of the output circuitry for one channel of the NI USB-9264.
Figure 9.
Output Circuitry for One Channel of the NI USB-9264
When the module powers on, the channels output the startup voltage. Refer
to the
section for more information about startup voltage.
Refer to the software help for information about configuring startup output
states in software.
Connecting Wires to the NI USB-9264 Connector
Use a flathead screwdriver with a blade smaller than 2.3 × 1.0 mm
(0.09 × 0.04 in.) to connect wires to the detachable spring-terminal
connector. Insert the screwdriver into a spring clamp activation slot and
press a wire into the corresponding connector terminal, then remove the
screwdriver to clamp the wire into the terminal. Refer to the
section for more information about spring-terminal wiring. Refer to
Figure 10 for an illustration of connecting wires to the NI USB-9264.
