Input Devices
Introduction
This user guide describes how to use the National Instruments USB-9215
Series and lists the specifications. In this document, the NI USB-9215/9215A
with screw terminal or backshell and NI USB-9215A with BNC are referred to
inclusively as the NI USB-9215 Series.
The NI USB-9215 Series data acquisition devices provide a USB interface
for four channels of 16-bit simultaneous sampling analog inputs with
integrated signal conditioning. The NI USB-9215 Series consists of
two components: an NI 9215 module and an NI USB-9161/9162 USB
carrier, as shown in Figure 1.

Page 11: Led Indicator
LED Indicator The NI USB-9215 Series device has a green LED next to the USB connector. The LED indicator indicates device status, as listed in Table 2. 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 connection. - Page 12 Each channel of the NI USB-9215 Series has a terminal or center pin to which you can connect the positive voltage signal, AI+, and a terminal or shield to which you can connect the negative voltage signal, AI–. The NI USB-9215 with screw terminal also has a common terminal, COM, that is internally connected to the isolated ground reference of the module.
- Page 13 NI USB-9215 is not accurate. To keep the voltage source within the common-mode range, connect the negative lead of the signal to COM through a 1 MΩ resistor, as shown in Figure 9. The NI USB-9215A with © National Instruments Corporation...
