Page 10: Connecting Sourcing-Output Devices
You can connect sourcing-output devices to the NI 9437. You must connect a supply voltage to the V pin on the NI 9437. Input channels on the NI 9437 read ON or OFF depending on the threshold set by the V pin. The V... -
Page 11: Connecting A Split-Rail Power Supply
Connecting a Split-Rail Power Supply You can connect a split-rail power supply to the NI 9437. A split-rail power supply consists of a floating power supply that is weakly centered around earth ground using bias resistors. Figure 4. Connecting a Split-Rail Power Supply... - Page 12 The NI 9437 has eight LEDs to display the ON/OFF state of the eight channels. When an LED is lit, the corresponding channel is ON and data is being read from the NI 9437. When an LED is dark, the corresponding channel is OFF.
