Descrição

The OMB-DAQBOARD-500 has been discontinued. Please see the OMB-DAQBOARD-2000 as a possible substitute or contact our Data Acquisition department.

The OMB-DAQBOARD-500 and OMB-DAQBOARD-505 are low-cost, 16-bit/200 kHz data acquisition boards. Each board offers 16 channels of 16-bit analog input, 24 digital I/O lines, and one counter input. The OMB-DAQBOARD-500 also provides two 16-bit waveform-capable analog outputs. Software supported by the OMB-DAQBOARD-500 Series includes Visual Studio and Visual Studio.NET, with examples for Visual C++, Visual C#, Visual Basic, and Visual Basic.NET, plus comprehensive drivers for DASYLab and LabVIEW. DaqView software is also included for quick and easy setup and data collection without programming.

Signal I/O
One 68-pin connector on the OMB-DAQBOARD-500 Series provides access to all the input and output signals. Unlike other multifunction boards that require multiple PC slots to access the I/O, the OMB-DAQBOARD-500 Series accommodates all I/O by using one cable and a single PCI slot. The latching 68-pin I/O connector contains all analog input channels, plus digital I/O lines, counter input, timer outputs, and analog outputs.

Analog Input
The OMB-DAQBOARD-500 Series has a 16-bit, 200 kHz A/D converter coupled with 16 single-ended or 8 differential analog inputs. Eight software-programmable ranges provide inputs from ±10 V to ±1.25 V full scale. Each channel can be software configured for a different range, as well as for single-ended or differential and bipolar or unipolar input.

Bus Mastering DMA
The OMB-DAQBOARD-500 Series supports bus mastering DMA, which allows analog input data, as well as analog and digital output data, to flow between the PC and the OMB-DAQBOARD-500 Series without consuming valuable CPU time. The driver supplied with the OMB-DAQBOARD-500 Series, as well as all other third-party software support such as LabVIEW, automatically use bus mastering DMA to efficiently conduct I/O from the PC to the data acquisition board.

Analog Output
The two OMB-DAQBOARD-500 16-bit, 100 kHz analog output channels are built into the board, with software-selectable output ranges of ±10 V and 0 to 10 V. Through the use of bus mastering DMA, each D/A output can continuously output a waveform. In addition, a program can asynchronously output a value to either of the D/As for non-waveform applications, assuming that the D/A is not already being used in the waveform output mode. When used to generate waveforms, the D/As can be clocked in several different modes, as described on the next page.

Asynchronous Internal Clock
The on-board programmable clock can generate updates ranging from 0.0009 Hz to 100 kHz, independent of any acquisition rate.

Asynchronous External Clock
A user-supplied external input clock can be used to pace the D/A, entirely independent of analog inputs.

Digital Inputs and Outputs
Twenty-four TTL-level digital I/O lines are included in the OMB-DAQBOARD-500 Series. They are divided into three 8-bit ports. Ports can be programmed as either input or output.

Counter Inputs
One 16-bit counter is built into the OMB-DAQBOARD-500 Series, capable of counting up to 65,536 TTL-level transitions. The counter will accept frequency inputs up to 900 kHz.

Timer Outputs Two 16-bit timer outputs are included in the OMB-DAQBOARD-500 Series, each capable of generating square waves with a programmable frequency range of 7.7 Hz to 500 kHz.

Multiple DaqBoards per PC
All of the features described for the OMB-DAQBOARD-500 Series can be replicated with up to 4 DaqBoards installed in the same PC. When multiple boards are installed, all boards can be operated synchronously. The OM-TB-100 screw-terminal board (shown on previous page) makes it easy for the user to attach signals to the OMB-DAQBOARD-500 Series boards.

Analog Outputs (OMB-DAQBOARD-500 Only)
The 2 analog output channels are updated asynchronously relative to scanned inputs and clocked from an internal on-board clock or an external clock source. Analog outputs can be updated asynchronously, independent of any other scanning in the system. Bus mastering DMA provides CPU and system-independent data transfers, ensuring accurate outputs independent of other system activities. Ouput from memory is supported, allowing continuous waveform outputs.
