The DAS-1200 is a high speed data acquisition board for IBM PC and compatible computers. It features the versatile DAS-1200 multifunction board and DriverLinx driver software. The DAS-1201 and DAS-1202 are high speed analog and digital interface boards. The DAS-1201 supports high gains and has a maximum sample rate of 50,000 samples per second, while the DAS-1202, which supports low gains, is rated to 100,000 samples per second.
Input ranges are switch selectable from switches conveniently located on the backplate at the rear of the computer.
Data transfer can be accomplished in 3 ways: by program control, interrupt service routine, or DMA. All modes are software selectable. Demand mode DMA capability allows up to full sample rates in both PC/XT, AT and above computers. This demand mode helps to insure reliable data transfer. Counters within the DAS-1200's ASIC provide burst mode sampling capability which can be used to emulate simultaneous sample-and-hold (SSH) operation (with a minimum 10 ╡sec channel to channel skew).
32-bits of digital I/O are available. 8-bits (4 input, 4 output) are brought out on the main 37-pin connector. The remaining 24-bits are bi-directional and are available on the auxiliary connector for your application. These 24 bits are divided into two 8-bit ports and two 4-bit ports. Each port is set individually as input or output. configurable plot attributes, printer and plotter support for data plot and table hard copy.
Driver Software
DriverLINX software is also included, at no additional charge, with every
DAS-1200 series board. Supporting your programming requirements in Windows
3.x/95 environments, DriverLINX provides application developers a standardized
interface to over 100 services for creating foreground and background tasks to
perform analog input and output, digital input and output, time and frequency
measurement, event counting, pulse output and period measurement. In addition
to basic I/O support, DriverLINX also provides sophisticated built-in
capabilities to handle memory and data buffer management, a rich selection of
starting and stopping trigger events including pre-, mid-point, and post
triggering protocols, extensive error checking and reporting capabilities, and
a context-sensitive on-line help system. There are two versions included:
DriverLINX and DriverLINX/VB. DriverLINX provides the C/C++interfaces.
DriverLINX/VB provides custom control interfaces (VBX and ActiveX) that can be
accessed from the palette of built-in tools included in Microsoft's Visual
Basic and Visual C environments. Software is supplied on CD-Rom.
Terminal Panel with Cable
All inputs and outputs on the
DAS-1200 board are accessed through two 37 Pin D male connectors, which consist
of a main and auxiliary I/O connector. The main connector contains all analog
inputs, counter connections and 8 digital I/O lines. The auxiliary I/O
connector contains an additional 24 channels of digital I/O. If both connectors
need to be used at the same time, two terminal panels and two cables are
required.
