USB-230 Series devices provide improved cost/performance compared to our similarly priced 16-bit DAQ devices. The USB-231 and USB-234 both offer eight analog inputs, two analog outputs, eight DIO channels, and one counter input.

Analog Input
Both USB-230 Series devices provide four differential (DIFF)/eight 16-bit single-ended (SE) analog inputs with a fixed analog input range of ±10 V.

Sample Rate
The maximum continuous sample rate is an aggregate rate for USB-230 Series devices, up to 100 kS/s.

Analog Output
USB-230 Series devices provide two 16-bit analog outputs. One or both outputs can be updated at a rate up to 5 kS/s per channel. The output range is fixed at ±10 V.

Digital I/O
Eight TTL-level digital I/O lines are included with USB-230 Series devices. Each digital channel is software-selectable for input or output.

Digital input voltage ranges from 0 V to 5 V are permitted, with thresholds of 0.8 V (low) and 2.3 V (high).

When used in output mode, each digital channel allows for 3.3 V operation with a source/sink current limit of V4 mA.

All DIO lines are set to high-impedance inputs at system startup and reset. The device does not drive the signal high or low. Each line has a weak pull-down resistor connected to it.

All digital I/O updates and samples are software-paced.

Digital Trigger Input
USB-230 Series devices include an external digital trigger input that is software-selectable for rising edge or falling edge detection.

Counter Input
USB-230 Series devices support one 32-bit edge counter (rising) that accepts inputs up to 5 MHz.

Included Software
TracerDAQ® TracerDAQ® is an out-of-the-box application that allows data to be generated, acquired, analyzed, displayed and exported within seconds of installing Measurement Computing data acquisition hardware. TracerDAQ offers four different data acquisition applications; a Strip Chart, an Oscilloscope, a Function Generator and a Rate Generator, all of which are accessed via a common, easy-to-use menu page.
InstaCal InstaCal installation, configuration, and test software in one package simplifies these important steps as you turn your PC into a measurement system. Installation detects new hardware and configures your computer and DAQ device. Test routines verify that all the board's features are operating, and will speed you to a quick resolution.
Universal Library Universal Library programming libraries for Windows® Visual Studio® programming languages, and others. A complete function library to simplify the configuration and operation of your measurement board. A single, universal set of functions operates all our products so you only have to learn to use our library once.

ULx for NI LabVIEW™ ULx for NI LabVIEW™ Advanced Driver for use with NI LabVIEW™ 2010-2014. Allows quick development of instrumentation, acquisition, and control applications with Measurement Computing hardware devices
Additional Software
DASYLab® Software DASYLab® Software lets you interactively develop PC-based data acquisition applications by simply attaching functional icons. DASYLab offers real-time analysis, control, and the ability to create custom graphical user interfaces (GUIs). What’s more, in contrast to other graphical programming environments, which can require weeks of training to master, DASYLab has a very short user-learning curve. Many applications can be configured in a few minutes, rather than days or weeks.

TracerDAQ® Pro TracerDAQ® Pro provides four virtual instrument applications used to graphically display and store input data – and generate output signals – within minutes of installing Measurement Computing data acquisition hardware. The applications allow the user to customize appearance, store configurations for future use, save data to a file for export and – with the use of interactive hotspots – change settings while the application is running.
