Multifunction DAQ board for PCI Express bus
11 June 2012
Measurement Computing Corporation has announced the release of the PCIe-DAS1602/16 multifunction DAQ board for the PCI Express bus.
Available from Adept Scientific, the 16-bit PCIe-DAS1602/16 offers 16 analogue inputs, a 100kS/s sample rate, 32 digital I/O, two analogue outputs and three counter inputs.
The PCIe-DAS1602/16 is also connector and software compatible with the MCC PCIM-DAS1602/16 for existing customers with the need to migrate to PCI Express.
The PCIe-DAS1602/16 includes a variety of software options to meet any skill level or application requirement. Support includes out of the box TracerDAQ along with comprehensive drivers for Visual Studio and Visual Studio .NET, DASYLab, and NI LabVIEW. The board provides 16 single-ended (SE) or eight differential (DIFF) input channels with 16-bit resolution, two 12-bit analogue outputs, 32 DIO, and three 16-bit counters. The PCIe-DAS1602/16 is a fully connector-compatible and software-compatible replacement for the Measurement Computing PCIM-DAS1602/16.
The PCIe-DAS1602/16 provides 16 SE or eight DIFF analogue inputs. The input mode is switch-selectable to configure all channels as either SE or DIFF. The board offers bipolar analogue input ranges of ±10 V, ±5 V, ±2.5 V, and ±1.25 V, and unipolar ranges of 0 V to 10 V, 0 V to 5 V, 0 to 2.5 V, and 0 V to 1.25 V. Input ranges are software-selectable, and polarity is switch-selectable.
The PCIe-DAS1602/16 offers a single-channel sample rate of 100 kS/s divided by the number of channels being sampled.
Two 12-bit multiplying digital-to-analogue converters (DACs) provide analogue output on the PCIe-DAS1602/16. DAC0 and DAC1 each accept a precision 5 V or 10 V reference, which provides onboard D/A unipolar ranges of 0 V to 5 V and 0 V to 10 V, and bipolar ranges of ±5 V and ±10 V.
Other ranges between 0 V and 10 V are available when an external precision voltage reference is supplied to the DAC0 REF IN pin or DAC1 REF IN pin of the main connector.
Onboard reference voltage, user-supplied reference voltage, and polarity are all jumper-selectable.
The 24 digital I/O connections available on the 40-pin DIO connector of the PCIe-DAS1602/16 are available as two eight-bit ports (ports A and B) and two four-bit ports (ports CH and CL). Each port can be configured independently as either input or output. These ports default to the input state (high impedance) on power up or reset.
The eight digital I/O connections available on the main 37-pin connector consist of two 4-bit ports. One port is permanently configured as input, and the other port is permanently configured as output.
The PCIe-DAS1602/16 also includes jumpers to set the digital bits for pull-up (+5 V) or pull down (0 V) when the board is powered on and reset. Ports A, B, CH, and CL are factory-configured for pull-up (+5 V).
Each PCIe-DAS1602/16 offers three 16-bit down counters. Each counter accepts frequency inputs up to 10 MHz, and provides clock, gate, and output connections.
The frequency of the square wave used as a clock by the A/D pacer circuitry is jumper-selectable for 1 MHz (default), or 10 MHz. The internal pacer output driving the A/D converter is also available at pin 20 (CTR 3 Output) on the main 37-pin I/O connector.
The A/D pacer clock trigger edge (rising or falling) that initiates the A/D conversions is jumper-selectable on the PCIe-DAS1602/16. The jumper is configured for rising edge by default. The PCIe-DAS1602/16 can be fully calibrated either at the factory or in the field using InstaCal.
