Apple Mac users can now benefit from an affordable data acquisition solution in the form of the new DAQPlot software and the popular USB-based LabJack U12
The LabJack U12 has a +/-10V input range at 12-bit resolution.
Differential channels can make use of the low noise precision amplifier with gains of 1,2,4,8,16,20, giving an input range down to +/-1V.
Data can be streamed to disk at 1kHz and a bursts mode allows over 4000 samples to de taken at a 8kHz rate.
The two 0-10V analogue output channels can be updated at a 50Hz rate with 10-bit resolution.
The LabJack has 20 digital I/O channels which can be individually configured as input or output.
There is also one 32-bit counter available on the LabJack U12, capable of counting frequencies up to 1 MHz.
The LabJack U12 also has a watchdog timer function available, which can change the states of digital I/O if the LabJack does not successfully communicate with the PC within a specified time-out period.
This function could be used to reboot the PC allowing for reliable unattended operation.
All this from a simple plug-and-play USB device.
The OEM version consists of a populated circuit board with the usual screw terminals replaced with DIL headers.
It does not come with an enclosure, USB cable or a software CD.
However, all software and a dimensional drawing is available from Audon's website.
The OEM version is ideal for users who wish to add the U12 functionality to their own equipment or have an extremely cost-sensitive application in mind.
Software support for the U12 is very extensive.
There is an easy-to-use DLL and ActiveX and LabView VI.
There are also freely available examples in Visual Basic, C++, Borland C, PowerBasic, MatLab, Delphi, LabVIEW, TestPoint, VEE, DAQFactory, LabWindows, Perl, Java, DasyLab and even Excel.
There is also driver information for Linux and Apple Mac users.
