Introduction 1

The DaqBoard/500 and DaqBoard/505 have 16 single-ended or 8 differential analog inputs multiplexed
to a 16-bit A/D converter with maximum throughput of 200 kHz, programmable gains of 1, 2, 4 or 8, one
counter input channel, two timer output channels, and 24 lines of digital I/O. In addition, DaqBoard/500
includes two clocked DACs.

The boards feature a DMA engine for optimum performance in supported Windows environments. Board
connections are terminated in a 68-pin “high density” SCSI III connector at the rear of the PC.

A digital calibration method is used for both analog-to-digital and digital-to-analog
conversions. Please contact the factory should you believe your board to be in need
of calibration.

Board Features

Analog I/O

DaqBoard/500 Series boards support 16 single-ended or 8 differential analog inputs multiplexed to a 16-bit
A/D converter. The input multiplexer is supported by a 176 element channel gain RAM which allows the
board to select gain on a per channel basis and to access channels in any order. The 16-bit A/D has a
maximum throughput of 200 kHz. An A/D Pacer clock is provided to allow sampling rates from 0.0009 Hz
to 200 kHz. The DaqBoard/500 includes two DACs for analog output.*

Digital I/O

DaqBoard/500 Series boards have 24 lines of TTL level digital I/O programmable in three 8-bit ports as
either inputs or outputs. All 24 lines are brought out via the main 68-pin SCSI III connector.

Counter 1

Counter 1 (CNTR1) can provide either cumulative or incremental counting capabilities. The counter is
capable of counting 5 V LSTTL rising edges to a maximum count of 131071 decimal.

Timer 0 and Timer 1

Timer0 (TMR0) and Timer1 (TMR1) provide a 50% duty cycle square wave 5 V LSTTL output with an
output frequency range of 7.7 Hz to 500 kHz. The Timer’s output frequency is based on a 1 MHz
oscillation with a divisor of 1 to 65536 decimal.

PCI Interface

DaqBoard/500 Series boards communicate to the PCI bus through an interface controller. The boards are
fully plug-and-play and have no switches, potentiometers, or jumpers. The boards feature digitally
calibrated A/D and D/A’s, and plug-and-play compatibility to provide automatic integration into the PC’s
configuration when first installed.

The PCI interface provides access to all on-board registers for software configuration of all on-board
functions. For maximum performance, the boards feature a 32-bit bus-mastering DMA engine on the
ADC and DAC hardware to provide high-speed transfers between the board and system memory.

DMA Engine

Interrupt latency on the PCI bus can be extremely inefficient for high-speed data acquisition. For this
reason, DaqBoard/500 and DaqBoard/505 each use an onboard DMA engine. The engine [analogous to
the older ISA type DMA controller] supports scatter/gather (buffer chaining) with a pair of chain address
registers. These registers point to system memory for use in the buffered transfer.

The DMA controller is loaded with the previously allocated physical addresses of the buffers and only
generates interrupt requests when the current transfer buffer has been completed. This reduces the burden
of CPU interrupt intervention.

Both analog input and analog output channels* have on-board DMA engine support for high-speed data
transfers. The two analog output channels have individual DMA engines and clocking methods available.
The DAC1 clocking source may be set to the DAC0 clocking source to allow simultaneous DAC transfers.

All PCI bus transfers are 32-bit operations. Analog input and analog output transfers are each
independently software selectable to allow either 16-bit or 32-bit data transfers. An immediate
improvement of twice the memory bandwidth can be achieved by transferring two analog input data points
[or two analog output data points] into memory as a single 32-bit PCI transfer.

* The DAC analog output channels apply to DaqBoard/500 only.
