NI USB-9263 User Guide and Specifications
The NI USB-9263 has a 10-terminal, detachable screw-terminal connector
that provides connections for four analog output channels. 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 Applications
National 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. Refer to Figure 7 for an illustration.
