OMEGAÆs DAQ-1200 series are data acquisition systems with 12-bit analog input, 32-bit digital I/O, two channels of D/A, and three 16-bit programmable timer/counters. The maximum sampling rate is 330 KHz for the DAQ-1100 and 400 KHz for the DAQ-1200.
The DAQ-1200 offers
16 channel single-ended or eight channel differential analog inputs with 12-bit resolution. The input voltage is jumper selectable for either unipolar or bipolar ranges. The DAQ-1101 and DAQ-1201 provide software programmable gains of 1, 10, 100, and 1000. The DAQ-1102 and DAQ-1202 provide software programmable gains of
1, 2, 4, and 8. The analog I/O connection, eight bits of digital I/O and their control lines, are accessed via a D-37 connector that fits in the rear slot of a PC. A second auxiliary D-37 connector is provided to the user for adding up to 24 additional digital I/O lines. This is via a ribbon cable from the board which will need to occupy an additional opening in the back of the PC.
The DAQ-1200 contain a data FIFO. The data FIFO provides the cushion for the stream of data coming from the output of A/D conversion and can facilitate the data integrity using interrupts under Windows. The DAQ-1200 also contains a scan list FIFO.
The SCAN LIST FIFO is used for scanning the input channels with their corresponding gains.
SOFTWARE:
The DAQ-1100/1200 is supplied with DaqEZ software. DaqEZ is a Windows application which provides real-time data display and datalogging to disk. Once the data is stored to disk it may be imported to spreadsheet and other data analysis programs. Also supplied are software drivers.
The software drivers provide support for various programming languages such as Microsoft C/C++, QuickBasic, TURBO PASCAL. A Dynamic Link Library (DLL) is furnished for all kinds of programming languages under Microsoft Windows. An optional Visual Basic Controls (VBX) called VISUALDAQ is also available for only $195. Third party software is also available for implementing a fully integrated data acquisition system without programming, called LABTECH NOTEBOOK and
Snap-Master.
UIO-37:
Both the main analog I/O connector and the auxiliary digital I/O connector use a standard male 37 pin D-type format. For easy field wiring to the connectors the UIO-37 terminal panel may be used. One UIO-37 is needed for each connector. A CP-DAQ cable is also required to connect each UIO-37 to the DAQ-1100/1200
