Beschreibung

The DAQ-800 is no longer available. Please see the OME-PCI-1002 as a possible PCI alternative or contact our Data Acquisition department.

OMEGA’s DAQ-801/802 is a low cost data acquisition system with 12-bit resolution, eight channel analog input, two channel D/A output, 32-bit digital I/O, and one 16-bit programmable timer/counter for ISA bus computers (IBM PC/AT or compatible). The maximum sampling rate is 40 KHz for A/D with internal or external triggering.

The DAQ-801/802 offers software selectable eight channel singleended or differential analog inputs with 12-bit resolution. The input voltage can be either unipolar or bipolar, and is jumper selectable. DAQ-801 provides programmable gains of 1, 10, 100, and 1000. The DAQ-802 has programmable gains of 1, 2, 4 and 8. Both the DAQ-801 and DAQ-802 have auto zeroing and self-calibrating facility for A/D conversion. The main D-37 connector on the board accessed through the rear of the PC is for analog I/O, control lines and 8-bit digital I/O. A second auxiliary D-37 connector is provided for the additional 24 digital I/O lines from an 8255 programmable peripheral interface chip.

There is a 1024 sample data FIFO available which provides a cushion for the data stream coming from the output of the A/D converter. This protects data integrity when using an interrupt routine under Windows or other operating systems. SCAN LIST capability is also provided for scanning the input channels with their corresponding gains. Sequential scanning between any two channels can be programmed.

The DAQ-801/802 can be installed in any available I/O base address location without conflict with presently installed devices. The board can be enabled or disabled through software manipulation. The interrupt levels are register selectable through software from IRQ 2-7, 10-12, 14 and 15. The 24 digital I/O lines for the second D-37 connector are directly from an 8255 programmable peripheral interface chip.

Software
The DAQ-800 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 spread sheet 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, and Turbo Pascal. A dynamic link library (DLL) is furnished for programming most languages under Microsoft Windows.

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 these 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-800.
