NI USB-9201/9221

8-Channel, 12-Bit Analog Input Devices

This user guide describes how to use the National Instruments 
NI USB-9201/9221 devices and lists the specifications. In this user guide, 
the NI USB-9201/9221 with screw terminal and NI USB-9201/9221 with 
D-SUB are referred to inclusively as the NI USB-9201/9221.

Introduction

The NI USB-9210/9221 data acquisition device provides a USB interface 
for eight channels of 12-bit analog inputs with integrated signal 
conditioning. The NI USB-9201/9211 consists of two components: an 
NI 9201/9221 module and an NI USB-9162 carrier, as shown in Figure 1.
