Introduction
Chapter 1 Introduction
The PCI-1711U/UL is a universal PCI bus multifunction card. It offers
the five most desired measurement and control functions:
• 12-bit A/D conversion
• D/A conversion (PCI-1711U only)
• Digital input
• Digital output
• Timer/counter
A programmable-gain instrument amplifier lets you acquire different
input signals without external signal conditioning. An onboard 1K word
FIFO buffer provides high-speed data transfer and predictable performance under Windows. Automatic channel scanning circuitry and
onboard SRAM let you perform multiple-channel A/D conversion and
individual gains for each channel.
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-1711U cards.

PCI-1711U/UL offers the following main features:
PCI-Bus Plug & Play
The PCI-1711U 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-1711U/UL features an automatic channel/gain scanning circuit. This
circuit, instead of your software, controls multiplexer switching during
sampling. On-board SRAM stores different gain values for each channel.
This combination lets user perform multi-channel high-speed sampling
(up to 100 kHz) for each channel.
Onboard FIFO Memory
There are 1K samples FIFO for A/D (AI) on PCI-1711U/UL. This is an
important feature for faster data transfer and more predictable performance under Windows system.

Chapter 1
Onboard Programmable Timer/Counter
PCI-1711U/UL provides a programmable timer counter for generating
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-1711U/UL has a built-in DIP switch that helps define each card’s ID
when multiple PCI-1711U/UL cards have been installed on the same PC
chassis. The BoardID setting function is very useful when building a system with multiple PCI-1711U cards. With the correct BoardID settings,
you can easily identify and access each card during hardware configuration and software programming.

Chapter 3 Signal Connections
3.1 Overview
Maintaining signal connections is one of the most important factors in
ensuring that your application system is sending and receiving data correctly. A good signal connection can avoid unnecessary and costly damage to your PC and other hardware devices. This chapter provides useful
information about how to connect input and output signals to the PCI1711U cards via the I/O connector.
3.2 Switch and Jumper Settings
PCI-1711U cards have one switch for BoardID setting.
Figure 3.1: Connector and Switch Locations
BoardID settings are used to set a board’s unique identifier when multiple
identical cards are installed in the same system.
PCI-1711U 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 BoardID switch’s unique identifier has been set to 0 at the factory.

3.4 Field Wiring Considerations
When you use PCI-1711U cards to acquire data from outside, noises in
the environment might significantly affect the accuracy of your measurements if due cautions are not taken. The following measures will be helpful to reduce possible interference running signal wires between signal
sources and the PCI-1711U 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 interference. 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 distance 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 recommend that you use the PCL-10168 shielded cable.

Calibration
Appendix C Calibration
PCI-1711U cards are calibrated at the factory for initial use. However, a
recalibration of the analog input and the analog output function is recommended:
1. Every six months.
2. Everytime the analog output range is changed.
We provide the Advantech Device Manager on the companion CD-ROM
to assist you with D/A and A/D calibration. The Advantech Device Manager makes calibration easy. 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.
The Advantech Device Manager can be accessed through the Start button:

C.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 A/D calibration tool in the Advantech Device Manager leads you
through the whole A/D offset and gain adjustment procedure. The basic
steps are outlined below:
1.
Connect a DC voltage source of +9.995 V to AI0.
2.
Connect AGND to AI1, AI2, AI3, AI4 and AI5.
3.
Run the ADCAL.EXE program.
4.
Adjust VR2 until the output codes from the card’s AI0 are focused
on FFE (at least 70%), and adjust VR1 until the output codes from
the card’s AI1, AI2, AI3, AI4 and AI5 are focused on 7FF (at least
70%).
5.
Press the SPACE key to finish A/D calibration.
C.3 D/A Calibration (PCI-1711U)
Note:
Using a precision voltmeter to calibrate the D/A
outputs is recommended.
In a way similar to the A/D Calibration, the D/A calibration tool in the
Advantech Device Manager leads you through the whole D/A calibration
procedure.
1.
Measure the DA0 output with a 4 1/2-digit digital meter. Adjust the
VR3 until the output value equals 4.9988V.
2.
Measure the DA1 output with a 4 1/2-digit digital meter. Adjust the
VR4 until the output value equals 4.9988V.
3.
The D/A calibration is finished.
