Chapter 1 Introduction

Thank you for buying the Advantech PCI-1718HDU/HGU. PCI-

1718HDU/HGU is a PCI-Bus multifunction card for IBM PC/XT/AT or

compatible computers. It offers the five most desired measurement and

control functions:

• 12-bit A/D conversion

• D/A conversion

• Digital input

• Digital output

• Timer/counter.

A programmable-gain instrument amplifier lets you acquire different

input signals without external signal conditioning. An onboard 1 K word

FIFO buffer provides high-speed data transfer and predictable perfor-

mance under Windows. Automatic channel scanning circuitry and

onboard SRAM let you perform multiple-channel A/D conversion with

DMA and individual gains for each channel.

PCI-1718HDU/HGU is compatible* with its ISA-Bus predecessor, the

PCL-818HD/HG. This puts rich software support and a wide variety of

external signal conditioning boards at your disposal.

The following sections of this chapter will provide further information

about features of the multifunction cards, a Quick Start for installation,

together with some brief information on software and accessories for the

PCI-1718 cards.

Note*

1. PCI-1718HDU/HGU is register-level- pro-

gramming compatible with PCL-818HD/HG

2. Due to the difference between ISA and PCI

architecture, we use “interrupt + FIFO” to emu-

late the DMA function. But it makes no differ-

ence to your programming and applications.

1.1 Features

• Register level programming compatible with PCL-818HD/HG

• 16 single-ended or 8 differential A/D inputs, switch selectable

• 12-bit A/D converter, up to 100 kHz sampling rate

• Programmable gain for each input channel

• Automatic Channel/Gain Scanning

• On-board 1 K word FIFO buffer with software selectable interrupt

• Software selectable Bipolar/Unipolar analog input ranges

• 16 digital inputs and 16 digital outputs, TTL/DTL compatible

• One 12-bit analog output channel

• Data transfers by program control and interrupt handler routine

• Universal PCI-Bus (Support 3.3V or 5V PCI-Bus signal)

• BoardID switch

PCI-1718HDU/HGU offers the following main features:

PCI-Bus Plug & Play

The PCI-1718 cards use a PCI controller to interface the card to the PCI

bus. The controller fully implements the PCI bus specification Rev 2.2.

All configurations related to the bus, such as base address and interrupt

assignment, are automatically controlled by software. No jumper or

switch is required for user configuration.

Automatic Channel/Gain Scanning

PCI-1718HDU/HGU features an automatic channel/gain scanning circuit.

This circuit, instead of your software, controls multiplexer switching dur-

ing sampling. On-board SRAM stores different gain values for each chan-

nel. This combination lets user perform multi-channel high-speed

sampling (up to 100 kHz) for each channel.

Onboard FIFO

There are 1 K samples FIFO for A/D (AI) on PCI-1718HDU/HGU. This

is an important feature for faster data transfer and more predictable per-

formance under Windows system.

Onboard Programmable Timer/Counter

PCI-1718HDU/HGU provides a programmable timer counter for generat-

ing pacer trigger for the A/D conversion. The timer/counter chip is

82C54, which includes three 16-bit counters of 10 MHz clock. One

counter is used as an event counter for counting events coming from the

input channel. The other two are cascaded together to make a 32-bit timer

for pacer trigger time base.

BoardID Switch

PCI-1718HDU/HGU has a built-in DIP switch that helps define each

card’s ID when multiple PCI-1718HDU/HGU cards have been installed

on the same PC chassis. The BoardID setting function is very useful when

building a system with multiple PCI-1718 cards. With the correct Boar-

dID settings, you can easily identify and access each card during hard-

ware configuration and software programming.

Note:

For detailed specifications of the PCI-

1718HDU/HGU, please refer to Appendix A.

3.1 Overview

Maintaining signal connections is one of the most important factors in

ensuring that your application system is sending and receiving data cor-

rectly. A good signal connection can avoid unnecessary and costly dam-

age to your PC and other hardware devices. This chapter provides useful

information about how to connect input and output signals to the PCI-

1718 cards via the I/O connector.

3.2 Switch and Jumper Settings

3.2.1 Setting the BoardID Switch (SW1)

BoardID settings are used to set a board’s unique identifier when multiple

identical cards are installed in the same system.

PCI-1718 cards have a built-in DIP switch (SW1), which is used to define

each card’s unique identifier. You can determine the unique identifier in

the register as shown in Table 3.1. If there are multiple identical cards in

the same chassis, the BoardID switch helps differentiate the boards by

identifying each card’s device number with the switch setting. The Boar-

dID switch’s unique identifier has been set to 0 at the factory.

If you need to adjust it to other numbers, set SW1 by referring to DIP

switch settings below.

3.2.2 Channel Configuration, S/E or DIFF (SW2)

The PCI-1718 cards offer 16 single-ended or eight differential analog

input channels. Slide switch SW2 changes the channels between single-

ended or differential input. Slide the switch to the left-hand position,

marked DIFF, for eight differential inputs (the default) or to the right-

hand position, marked S/E, for 16 single-ended inputs.

3.2.3 D/A Reference Voltage, int./ext. (JP11)

Jumper JP11 selects reference voltage source for PCI-1718 cards’ D/A

converters. You can use the cards’ internal reference, or supply an exter-

nal reference.

Table 3.3: Summary of Jumper JP11 Settings

Jumper

Function description

JP11

External

Internal (default)

When you set JP11 to INT, the D/A converter takes its reference voltage

input from the card's onboard reference. Jumper JP10 selects either -5 V

or -10 V onboard reference voltage. With JP11 set to INT the D/A chan-

nel has an output range of 0 to +5 V or 0 to +10 V, respectively.

PCI-1718 Series User Manual

Download from Www.Somanuals.com. All Manuals Search And Download.

When you set JP11 to EXT, the D/A converter takes its reference voltage

input from pin 31 of connector CN3. You can apply any voltage between

-10 V and +10 V to this pin to function as the external reference. The ref-

erence input can be either DC or AC (<100 kHz).

When you use an external reference with voltage V you can program

ref

the D/A channel to output from 0 V to -V , you can also use the D/A

ref

converter as a programmable attenuator. The attenuation factor between

reference input and analog output is:

Attenuation factor = G / 4095

G is a value you write to the D/A registers between 0 and 4095. For

example, if you set G to 2048, then the attenuation factor is 0.5. A sine

wave of 10 V amplitude applied to the reference input will generate a sine

wave of 5 V amplitude on the analog output.

3.2.4 Internal Voltage Reference, -10 V or -5 V (JP10)

If you use an internal reference voltage (set with JP11), the PCI-1718

cards provide a choice between -5 V or -10 V DC internal reference volt-

age sources.

3.2.5 Timer Clock Selection (JP8)

PCI-1718’s JP8 controls the input clock frequency for the 8254 program-

mable clock/timer. You have two choices: 10 or 1 MHz. This lets you

generate pacer output frequencies from 2.5 MHz to 0.00023 Hz (71 min-

utes/pulse).

The following equation gives the pacer rate:

Pacer rate = Fclk / (Divl * Div2)

Fclk is 1 MHz or 10 MHz, as set by jumper JP8. Div 1 and Div2 are the

dividers set in counter 1 and counter 2 in the 8254.

3.2.6 Ext. trigger and Counter Gate 0 Control (JP5)

JP5 has two jumpers. The upper jumper selects the card's A/D trigger

source when you use external triggering. The lower jumper selects the

gate control for counter 0 of the card's 8254 timer/counter.

3.2.7 Digital Output, 20-pin or 37-pin Connector (JP1)

The PCI-1718 cards’ JP1 switch digital output channels 0 to 3 between

the card's 20-pin connector and 37-pin connector. If you set the jumpers

to the left (D) side, the digital output signals will come out on connector

CN1 (20-pin). If you set the jumpers to the right (S) side, the output sig-

nals will come out on connector CN3 (37-pin).

These four digital output signals select the analog input channel when

you use a multiplexer/amplifier daughter board. Daughter boards with a

DB-37 connector, such as the PCLD-789D, read the digital output signals

from the DB-37 connector (CN3). With other daughter boards you will

need to connect an external 20-pin flat cable from CN1 to the daughter

board.

3.2.8 Setting the Time to Reset Digital Outputs

Some users will want the capability of clearing each digital output when

the system (or PC) issues a reset signal on the PCI bus. Other users will

want to clear their signal outputs only as part of system power-on.

PCI-1718 cards satisfy both these needs with jumper JP21. Depending on

the application, this capability may allow digital outputs to be “OFF”

without requiring a complete shutdown of processes controlled by the

card.

Complete loss of power to the chip clears the chip memory. Thus, no mat-

ter how JP21 is set, if the power to the PCI-1718 card is disconnected, the

digital output channel’s initial power-on state will be “OFF”.

3.3.2 Analog Input Connections

PCI-1718HDU/HGU supports either 16 single-ended or 8 differential

analog inputs. Switch SW2 selects the input channel configuration.

Single-ended Channel Connections

Single-ended connections use only one signal wire per channel. The volt-

age on the line references to the common ground on the card. A signal

source without a local ground is called a "floating" source. It is fairly sim-

ple to connect a single ended channel to a floating signal source. A stan-

dard wiring diagram looks like this:

Signal Input

To A/D

A.GND

Differential Channel Connections

Differential input connections use two signal wires per channel. The card

measures only the voltage difference between these two wires, the HI

wire and the LOW wire. If the signal source has no connection to ground,

it is called a "floating" source. A connection must exist between LOW

and ground to define a common reference point for floating signal

sources. To measure a floating sources connect the input channels as

shown below:

HIGH

Vin

LOW

A.GND

PCI-1718 Series User Manual

Download from Www.Somanuals.com. All Manuals Search And Download.

If the signal source has one side connected to a local ground, the signal

source ground and the PCI-1718HDU/HGU ground will not be at exactly

the same voltage, as they are connected through the ground return of the

equipment and building wiring. The difference between the ground volt-

ages forms a common-mode voltage.

To avoid the ground loop noise effect caused by common-mode voltages,

connect the signal ground to the LOW input. Do not connect the LOW

input to the PCI-1718HDU/HGU ground directly. In some cases you may

also need a wire connection between the PCI-1718HDU/HGU ground

and the signal source ground for better grounding. The following two dia-

grams show correct and incorrect connections for a differential input with

local ground:

Expanding Analog Inputs

You can expand any or all of the PCI-1718HDU/HGU's A/D input chan-

nels using multiplexing daughterboards. Daughterboards without D-type

connectors require the PCLD-774 Analog Expansion Board.

The PCLD-789(D) Amplifier and Multiplexer multiplexes 16 differential

inputs to one A/D input channel. You can cascade up to eight PCLD-

789(D)s to the PCI-1718HDU/HGU for a total of 128 channels. See the

PCLD-789(D) user's manual for complete operating instructions.

The PCLD-774 Analog Expansion Board accommodates multiple exter-

nal signal-conditioning daughter boards, such as PCLD-779 and PCLD-

789(D). It features five sets of on-board 20-pin header connectors. A spe-

cial star-type architecture lets you cascade multiple signal-conditioning

boards without the signal-attenuation and current-loading problems of

normal cascading.

The PCLD-8115 Screw Terminal Board makes wiring connections easy.

It provides 20-pin flat cable and DB-37 cable connectors. It also includes

CJC (Cold Junction Compensation) circuits.

Special circuit pads on the PCLD-8115 accommodate passive signal con-

ditioning components. You can easily implement a low-pass filter, atten-

uator or current shunt by adding resistors and capacitors.

Analog Output Connection

The PCI-1718HDU/HGU provides one D/A output channel. You can use

the internal precision -5 V or -10 V reference to generate 0 to +5 V or 0 to

+10 V D/A output. Use an external reference for other D/A output ranges.

The maximum reference input voltage is ±10 V and maximum output

scaling is ±10 V. Loading current for D/A outputs should not exceed 5

mA.

3.4 Field Wiring Considerations

When you use PCI-1718 cards to acquire data from outside, noises in the

environment might significantly affect the accuracy of your measure-

ments if due cautions are not taken. The following measures will be help-

ful to reduce possible interference running signal wires between signal

sources and the PCI-1718 card.

• The signal cables must be kept away from strong electromagnetic

sources such as power lines, large electric motors, circuit breakers or

welding machines, since they may cause strong electromagnetic inter-

ference. Keep the analog signal cables away from any video monitor,

since it can significantly affect a data acquisition system.

• If the cable travels through an area with significant electromagnetic

interference, you should adopt individually shielded, twisted-pair wires

as the analog input cable. This type of cable has its signal wires twisted

together and shielded with a metal mesh. The metal mesh should only

be connected to one point at the signal source ground.

• Avoid running the signal cables through any conduit that might have

power lines in it.

• If you have to place your signal cable parallel to a power line that has a

high voltage or high current running through it, try to keep a safe dis-

tance between them. Alternatively, you can place the signal cable at a

right angle to the power line to minimize the undesirable effect.

• The signals transmitted on the cable will be directly affected by the

quality of the cable. In order to ensure better signal quality, we recom-

mend that you use the PCL-10137 shielded cable.

Chapter 4 Programming Guide

4.1 Overview

The PCI-1718 cards are delivered with an easy-to-use 32-bit Device

Driver for user programming under the Windows 98/2000/XP operating

systems.

At the Windows driver level, PCI-1718 cards are fully compatible with

the PCL-818 series so you can easily use older applications of the PCL-

818 series with PCI-1718 cards.We also advise users to program the PCI-

1718 cards using the 32-bit Device Drivers provided by Advantech to

avoid the complexity of low- level registry programming.

4.2 Programming with the Driver

Your program can perform A/D by writing all the I/O port instructions

directly, or you can take advantage of the PCI-1718 driver. We suggest

that you make use of the driver functions in your program. This will make

you programming job easier and improve your program’s performance.

See the Software Driver User’s Manual for more information.

Start/Advantech Automation/Device Manager/Device Driver’s Manual

4.3 Register Programming.

The most important consideration in programming the PCI-1718 cards at

process of programming. The information in the following sections is

provided only for users who would like to do their own low- level pro-

gramming.

Without the driver you would do the following: perform software trigger,

pacer trigger with interrupt, pacer trigger with interrupt and FIFO, and

program a controlled data transfer.

Appendix C Register Structure & Format

C.1 Overview

PCI-1718 cards are delivered with an easy-to-use 32-bit Device Drivers

for user programming under the Windows 98/2000/XP operating sys-

tems. We advise users to program the PCI-1718 cards using the 32-bit

Device Drivers provided by Advantech to avoid the complexity of low-

level registry programming.

The most important consideration in programming the PCI-1718 cards at

the register level is to understand the function of the cards’ registers. The

information in the following sections is provided only for users who

would like to do their own low-level programming.

To get the DOS example programs, please access:

\CDROM\DOS\PCI\1718\

C.2 I/O Port Address Map

PCI-1718 cards require 32 consecutive addresses in the PC's I/O space.

The address of each register is specified as an offset from the card's base

address. For example, BASE+0 is the card's base address and BASE+7 is

the base address plus seven bytes.

Table C.1 shows the function of each register of PCI-1718 or driver, and

its address relative to the card's base address.

C.6 MUX Scan Channel Control — BASE+02H

The write register at BASE+02H controls multiplexer (MUX) scanning.

The high nibble provides the stop scan channel number, and the low nib-

ble provides the start scan channel number. Writing to this register auto-

matically initializes the MUX to the start channel. Each A/D conversion

trigger sets the MUX to the next channel.

With continuous triggering the MUX will scan from the start channel to

the end channel, then repeat. For example, if the start channel is 3 and the

stop channel is 7, then the scan sequence is 3, 4, 5, 6, 7, 3, 4, 5, 6, 7, 3, 4.

CL3

The MUX scan register low nibble, CL3 to CL0, also acts as a pointer

when you program the A/D input range (see previous section). When you

set the MUX start channel to N, the range code written to the register

BASE+01H is for channel N.

Programming example for PCI-1718HDU

This BASIC code fragment sets the range for channel 5 to ±0.625 V:

200 OUT BASE+2, 5 'SET POINTER TO CH.5

210 OUT BASE+1, 3 'RANGE CODE=3 FOR ±0.625 V

Note:

The MUX start/stop channel changes each time

you change the input range. Do not forget to reset

the MUX start and stop channels to the correct

values after you finish setting the range.

C.8 Digital I/O Registers - BASE + 03/0BH

The PCI-1718HDU/HGU provides 16 digital input channels and 16 digi-

tal output channels. You read digital input data from registers

BASE+03H and BASE+0BH. After the read operation the input lines go

to three-state (data is not latched).

You write digital output data to registers BASE+03H and BASE+0BH.

The registers latch the output value (you cannot read it back).

Using the PCL-818HD/HD/L's input and output functions is fairly

straightforward. Chapter 3 gives some ideas for digital signal connec-

tions.

C.9 D/A Output — BASE+04/05H

Write-only registers BASE+04H and BASE+05H accept data for D/A

output.

The PCI-1718 cards provide one D/A output channel with two double-

buffered 12-bit multiplying D/A converters. Write registers at addresses

BASE+04H and BASE+05H hold output data. DA0 is the least signifi-

cant bit (LSB) and DA11 is the most significant bit (MSB) of the D/A

data.

DA11 ~ DA0

DA0

Analog to digital data

The least significant bit (LSB) of the D/A data

The most significant bit (MSB)

DA11

When you write data to D/A channels, write the low byte first. The low

byte is temporarily held by a register in the D/A and not released to the

output. After you write the high byte, the low byte and high byte are

added and passed to the D/A converter. This double buffering process

protects the D/A data integrity through a single step update.

The PCi-1718 cards provide a precision fixed internal -5 V or -10 V refer-

ence, selectable by means of Jumper JP10. This reference voltage is

available at connector CN3 pin 11. If you use this voltage as the D/A ref-

erence input, the D/A output range is either 0 to +5 V or 0 to +10 V. You

can also use an external DC or AC source as the D/A reference input. In

this case, the maximum reference input voltage is ±10 V, and the maxi-

mum D/A output ranges are 0 to +10 V or 0 to -10 V.

Connector CN3 supports all D/A signal connections. Chapter 3 gives con-

nector pin assignments and a wiring diagram for D/A signal connections.

A/D status register is read-only, writing to it with any value will

clear the INT bit.

CN3 to CN0 When EOC = 0, these status bits contain the channel

number of the next channel to be converted.

Note:

If you trigger the A/D conversion with the on-board pacer or an external

pulse, your software should check the INT bit, not the EOC bit, before it

reads the conversion data.

EOC can equal 0 in two different situations: the conversion has com-

pleted or no conversion has been started. Your software should therefore

wait for the signal SNT = 1 before it reads the conversion data. It should

then clear the INT bit by writing any value to the A/D status register

BASE+08H.

Disable/enable generated interrupts

Disables the generation of interrupts. No interrupt signal can be sent

to the PC bus.

Enables the generation of interrupts. If DMAE = O the PCI-1718

card will generate an interrupt when it completes an A/D conversion.

Use this setting for interrupt driven data transfer.

If DMAE = 1 the PCI-1718HDU/HGU will generate an interrupt when it

receives a T/C (terminal count) signal from the PC's DMA controller,

indicating that a DMA transfer has completed.

Use this setting for DMA data transfer. The DMA transfer is stopped by

the interrupt caused by the T/C signal. See DMAE below.

Calibration

This appendix provides brief informa-

tion on PCI-1718 card calibration. Reg-

ular calibration checks are important to

maintain accuracy in data acquisition

and control applications.

Download from Www.Somanuals.com. All Manuals Search And Download.

Appendix D Calibration

PCI-1718 cards are calibrated at the factory for initial use. However, a

recalibration of the analog input and the analog output function is recom-

mended:

1. Every six months.

2. Everytime the analog output range is changed.

We provide a calibration program on the companion CD-ROM to assist

you with D/A calibration. The calibration programs make calibration an

easy job. With a variety of prompts and graphic displays, these programs

will lead you through the calibration and setup procedures, showing you

all the correct settings and adjustments.

Note:

If you installed the program to another directory,

you can find these programs in the corresponding

subfolders in your destination directory.

To perform a satisfactory calibration, you will need a 4½-digit digital

multi-meter and a voltage calibrator or a stable, noise-free DC voltage

source.

Note:

Before you calibrate the D/A function, you must

turn on the power at least 15 minutes to make sure

the DA&C card is already stable.

D.1 VR Assignment

The six variable resistors (VRs) on the PCI-1718HDU/HGU board help

you make accurate adjustment on all A/D and D/A channels. See the fig-

ure in Appendix B for help finding the VRs. The following list shows the

function of each VR:

D.2 A/D Calibration

Note:

Using a precision voltmeter to calibrate the

A/D outputs is recommended.

Regular and accurate calibration ensures maximum possible accuracy.

The CALB.EXE calibration program leads you through the whole A/D

offset and gain adjustment procedure. The basic steps are outlined below:

Short the A/D input channel 0 to ground and measure the voltage at TP1

on the PCB (see the figure in Appendix B). Adjust VR4 until TP1 is as

close as possible to 0 V.

Connect a DC voltage source with value equal to 0.5 LSB (such as the D/

A output) to A/D Channel O (pin 1 on connector CN3).

Adjust VR3 until the output from the card's A/D converter flickers

between 0 and 1.

Connect a DC voltage source with a value of 4094.5 LSB (such as the D/

A output) to A/D channel 0.

Adjust VR2 until the A/D reading flickers between 4094 and 4095.

Repeat steps 2 to step 5, adjusting VR2 and VR3.

Select unipolar input configuration. Connect a DC voltage source with a

value of 0.5 LSB (such as the D/A output) to A/D channel0. Adjust VR1

until the reading of the A/D flickers between 0 and 1.

D.3 D/A Calibration

Note:

Using a precision voltmeter to calibrate the D/A

outputs is recommended.

Connect a reference voltage within the range ±10 V to the reference input

of the D/A channel you want to calibrate. You can use either the on-board

-5 V (-10 V) reference or an external reference. Adjust the full-scale gain

and zero offset of the D/A channel with VR5 and VR6, respectively. Use

a precision voltmeter to calibrate the D/A output.

Set the D/A data register to 0 and adjust VR6 until the output voltage

equals 0 V.

Set the D/A data to 4095 and adjust VR5 until the D/A output voltage

equals the reference voltage minus 1 LSB, but with the opposite sign, For

example, if V is -5 V, then V should be +4.9988 V.
