Hardware Overview
The DI-1100 is a new release in a long line of low-cost starter kits from DATAQ Instruments. It’s an updated replacement and alternative
for the DI-145 USB data acquisition starter kit.
Suitable for measuring preamplified analog signals, the DI-1100 in tandem with the included WinDaq software allows real time data
acquisition, playback, and analysis performance equal to or better than other products that cost many times its low price. Predecessors of
this instrument have been sold to over 35,000 hobbyists and professionals for countless data acquisition applications around the world.
The DI-1100 continues this legacy with a higher resolution and faster ADC than its predecessor while retaining its noise-cancelling differential
analog inputs that are level-protected to ±100 VDC or peak AC. This is our fastest, most flexible, and value-oriented starter kit
ever. The DI-1100 offers four analog input and two discrete (digital) input channels. The analog inputs offer a fixed measurement range of
±10VFS, and are multiplexed to an integrated 12-bit ADC. Both analog and digital inputs are protected to ±100 and ±40 V dc or peak AC
respectively. Sample rates as slow as 20 Hz and as fast as 40 kHz with a single enabled channel are supported.
Software Overview
Model DI-1100 starter kit is provided with comprehensive software support. For point-and-click, ready-to-run applications the DI-1100
is supplied with our popular WinDaq software. WinDaq allows a real time display of any combination of analog channels and the ability
to stream acquired data to disk in recorder-like fashion, even at the fastest rate supported by the hardware. This is true streaming performance,
continuous, without gaps, and simultaneously to both the real time display and disk. Record only a few readings, or as many as
4 GB. The DI-1100’s two digital inputs are dedicated 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.
Sometimes, you need a more focused application. Consider a production application where an instrument makes the same measurements
and generates the same results repeatedly. This situation defines the need for a custom program, and the DI-1100 supplies the tools you
need to get it done. For Windows applications a .Net class is provided that accesses all DI-1100 measurement features. It’s provided with
a comprehensive example program that can act as the foundation for your unique application. For operating systems other than Windows
the DI-1100’s device protocol is fully documented.
