- Page 10 The NI 9215 with BNC has four BNC connectors. Each channel of the NI 9215 has an AI+ terminal or shield to which you can connect the positive voltage signal, and an AI– terminal or shield to which you can connect the negative voltage signal. The...
- Page 11 NI 9215. Connect the positive voltage signal to AI+ and the negative voltage signal to AI–. To connect grounded differential signals to the NI 9215 with screw terminal, you must also connect the signal reference to the COM terminal, as shown in Figure 4.
- Page 12 Figure 5. If the voltage source is outside of the common-mode range, then the NI 9215 does not read data accurately. The NI 9215 with BNC has internal circuitry that keeps the voltage source within the common-mode range.
- Page 13 Connecting Single-Ended Voltage Signals to the NI 9215 To connect single-ended voltage signals to the NI 9215 with screw terminal, you must also connect the ground signal to the COM terminal to keep the common-mode voltage in the specified range, as shown in Figure 6.
- Page 14 Wiring for High Vibration Applications If an application using the NI 9215 with screw terminal is subject to high vibration, National Instruments recommends that you either use ferrules to terminate wires to the detachable screw-terminal connector or use the NI 9932 backshell kit to protect the connections.
