DI-149 USB Data Acquisition Starter Kit
The DI-149 is a new product for general-purpose data acquisition applications in a long line of low-cost starter kits from DATAQ Instruments. Suitable for measuring preamplified analog signals, the DI-149 in tandem with the included WinDaq software allows real time data acquisition, playback, and analysis performance equal to or better that other products that cost ten times or more than its low price. Predecessors of this instrument have been sold to thousands of hobbyists and professionals for countless data acquisition applications around the world. The DI-149 continues this legacy with noise-cancelling differential analog inputs that are analog inputs that are transient-protected to ±150 VDC or peak AC. This tough and tolerant starter kit is an eight-channel version of the popular DI-145, with some enhanced capability.
The DI-149 offers eight analog and four discrete (digital) input channels. Two of the digital inputs (bits D2 and D3) can be used to measure rate up to 10 kHz and counts up to 16,383. The analog inputs offer a fixed measurement range of ±10 VFS at 10 bits of resolution. Sample rates as slow as 11.44 Hz (0.3052 Hz when using WinDaq software) and as fast as 10 kHz (divided by the number of enabled channels) are supported. Included WinDaq software allows a real time display of any combination of analog, digital, or counter/timer channels, and the ability to stream acquired data to disk in recorder-like fashion. Two digital inputs may be used for remote stop/start and remote event operations using WinDaq software. WinDaq also includes software to review recorded data files, including waveform analysis and data file export to Microsoft Excel and other applications.
The DI-149 is supplied with WinDaq/Lite software, which limits total sample throughtput to 240 Hz or lower. Optional WinDaq/HS allows the DI-149 to operate at the full 10 kHz rate. No throughput restrictions exist at the programming level.
Eight Analog Input Channels
Connect the DI-149 to any preamplified signal in the typical range of ±5 to ±10VFS.
10-bit ADC resolution
Provides 19.5 mV resolution across the entire DI-149 measurement range.
All eight DI-149 analog inputs transient-protected to ±150 VDC or peak AC. The four discrete inputs are protected to ±30 VDC or peak AC respectively. Accidents that happen are quickly forgiven.
Noise-cancelling Analog Input Configuration
The noise-immunity of differential inputs minimizes the effects of common mode noise so often encountered in industrial measurements.
Built-in USB interface
The DI-149 is provided with a built-in USB interface. Connect and run it with any laptop or desktop PC. The USB interface provides power to the DI-149, eliminating clumsy external power supplies.
Four Digital Inputs
Four discrete inputs allow remote event and stop/start operations with WinDaq software. Two double as counter/timer inputs for rate and totalize operations.
Wide OS support
Signed drivers are provided with the DI-149 that allow trouble-free installation for Windows XP and both 32- and 64-bit versions of Windows Vista and Windows 7.
WinDaq Software Included
Our WinDaq/Lite data acquisition software offers real time display and disk streaming for the Windows environment up to 240 Hz. The real time display can operate in a smooth scroll or triggered sweep mode of operation, and can be scaled into any unit of measure. Event markers with comments allow you to annotate your data acquisition session with descriptive information as you're recording to disk. Raise your productivity to new heights with WinDaq's unique multitasking feature. Record waveform data to disk in the background while running any combination of programs in the foreground — even WinDaq Playback software to review and analyze the waveform data as it's being stored! Playback supports waveform analysis (Statistics, X-Y plots, frequency analysis) and the ability to export data to Microsoft Excel. WinDaq/Lite recording and playback software is provided free with every DI-149 purchase. See the WinDaq Multimedia Tutorial for more information. Optional WinDaq/HS unlocks the 240 Hz real time recording restriction to allow sample rates to the full 10 kHz capability of the hardware.
Use the DI-149 with other programming languages
Although DATAQ Instruments provides ready-to-run WinDaq software with its DI-149 Data Acquisition Starter Kits, programmers will want the flexibility to integrate the DI-149 in the context of their own application. To do so they want complete control over DI-149 hardware, which can be accomplished by using the device at the protocol level. The DI-149 Protocol white paper describes how protocol-level programming is implemented across the Windows and Linux operating systems. First, we'll describe the virtual COM operation of the DI-149's interface and how communicating with the DI-149 is accomplished via a COM port hooked by the operating system. Then we'll define the DI-149's command set and scan list architecture and finish with a description of the DI-149's binary and ASCII response formats. Read the DI-149 Protocol.
