Chapter 1

Introducing the PC-CARD-DAS16/330

Overview: PC-CARD-DAS16/330 features

This manual explains how to install and use the PC-CARD-DAS16/330. This board is an ultra high-speed
analog input and digital I/O data acquisition and control board for PCMCIA bus computers with Type II slots.

Analog signals are routed to the A/D converter via a 16:1 single-ended multiplexer controlled by a register on
the card.

The input range is fully programmable in two bipolar ranges: ± 10 VDC or ± 5 VDC. You can trigger A/D
conversions with the on-board pacer clock, external pacer input or with software polling. The maximum sample
rate is 330 kHz.

Data may be transferred through software polling, an interrupt service or REP-INSW. A 4K sample FIFO
provides buffering between the A/D circuit and the PCMCIA bus. Half-full signaling from the FIFO permits
simultaneous loading and unloading of the FIFO, assuring that no samples are lost.

The board has eight digital I/O available on two 4-bit ports. The digital channels are software configurable as
eight inputs, eight outputs or four inputs and four outputs, and allow you to sense and control discrete events.

All signals pass through a 50-pin high-density connector. The board is completely plug-and-play, with no
switches or jumpers to set.

Functional Details

The PC-CARD-DAS16/330 provides the following features:

 16 single-ended analog inputs
 8 bits of digital I/O in two four-bit ports
 Resettable fuse
 50-pin I/O connector

Analog resolution & range

The 12-bit A/D converter provides a resolution of 1/4096 parts of full scale. The smallest reading of full scale
(1 part in 4096) is called a Least Significant Bit (LSB). Accuracy is specified in LSBs. Two bipolar ranges are
fully controlled by software:

Analog input ranges

Bipolar 1 LSB

±10 V 4.88 mV
±5 V 2.44 mV

The input range is controlled by a programmable amplifier.

Conversion speed and amplification

The A/D converter and sample & hold circuit captures and digitizes a signal in 3 µs. The time required to
complete an A/D conversion remains constant in all conditions and at all throughput rates. For example, when
you request a sample rate of 20 kHz, the A/D converter still converts the signal in 3 µs. The 20 kHz rate comes
from the fact that conversions are being initiated only every 50 µs.

Factors affecting conversion speed

There are two factors which may limit the conversion speed:



A/D converter - A 3 µs conversion speed translates to a maximum throughput of 330 kHz.
Analog front end - The front end consists of a multiplexer and a programmable gain amplifier. The speed



at which these circuits can switch can also limit the throughput of the A/D board. Throughput is defined as
the rate at which the A/D converter can acquire, convert and transfer a signal with full accuracy. Accuracy
is the key term - the A/D can always run at full speed, but the front end must settle before a true, accurate
signal can be captured.

17

PC-CARD-DAS16/330 User's Guide Functional Details

Input range vs. speed

The design of the analog front end is critical to maintaining total throughput. Most A/D converters have a fixed
input range, typically ±5V. The analog front end amplifies low level signals and adjusts bipolar signals to
match the A/D converter's standard input.

A poorly designed analog front end will show up very quickly in the throughput specifications - some designs
may have a high throughput in only one or two ranges, but is slower at other ranges. The PC-CARD­DAS16/330 achieves 330 kHz throughput in all ranges.

Triggering and transfer

A trigger is the event that begins an acquisition/transfer cycle. The trigger source used is programmable. There
are three possible trigger types:

 Internal programmable pacer output
 Software trigger
 External hard-wired trigger

The internal programmable pacer output trigger is the quotient of two 16-bit counters dividing a 10 MHz or
1 MHz pulse derived from a 10 MHz crystal oscillator. The trigger may be used to trigger any number of paced
conversions. A single conversion may be triggered by software at any time. The external trigger, pacer clock
and interrupt signals can be used to control conversions and synchronize to external events.

After a conversion is made, the sample is loaded in a FIFO buffer from which it may be retrieved one sample at
a time or in blocks via REP-INSW transfers.

FIFO size and design

The FIFO buffer stores samples from the A/D converter as they are being converted. When a block of samples
is ready and when the PC is ready, the FIFO is emptied into system memory. A properly designed FIFO of the
correct size is required for Windows, or samples will be lost at all but the slowest speeds.

Design of the FIFO is critical. Typically, FIFO designs employ a half-full transfer initiation circuit. The transfer
request is made when the FIFO is half full. Samples continue to fill the second half of the FIFO while the CPU
responds to the transfer request and transfers data to system memory.

The PC-CARD-DAS16/330 has a 4096-sample FIFO buffer - we have determined through extensive testing
that this size is optimum.

A/D pacer clock

Many analog acquisitions can be handled by a simple on-board rate divider that is created by combining a
crystal oscillator with a programmable counter. For those applications, the on-board 82C54 programmable rate
generator (counter) supplies the pacing. Some applications may require more flexible rate control.

Analog conversions can be externally paced, and thereby synchronized with events external to the PC.
Conversions can be held off until some external event, such as a not-to-exceed (alarm) condition is met.
Conversions can be externally gated so that samples are taken only when an event of interest is occurring, such
as a process going over normal limits.

linearity error. The theoretical worst-case error of the board may be calculated by summing these component
errors. Worst case errors are realized only in the unlikely event that each of the component errors are at their
maximum level, and causing error in the same direction.
