1.1 Introduction
The PCI-1710/1710HG is a multifunction DAS card for the PCI bus.
Advanced circuit design brings you higher quality and more func-
tions, including the five most desired measurement and control
functions: 12-bit A/D conversion, D/A conversion, digital input,
digital output, and counter/timer.
PCI-bus Plug and Play
The PCI-1710/1710HG uses a PCI controller to interface the card with
the PCI bus. The controller fully implements the PCI bus specifica-
tion Rev 2.1. All bus relative configurations, such as base address
and interrupt assignment, are automatically controlled by software.
No jumper or DIP switch setting is required for user configuration.
Flexible Inputs Types and Ranges Setting
The PCI-1710/1710HG features an automatic channel/gain scanning
circuit. The circuit, rather than your software, controls multiplexer
switching during sampling. The on-board SRAM stores different gain
values and configuration for each channel. This design lets you
perform multi-channel high-speed sampling (up to 100 kHz) with
different gains for each channel with free combination of single-ended
and differential inputs.
On-board FIFO (First In First Out) Memory
The PCI-1710/1710HG has an on-board FIFO buffer which can store
up to 4K A/D samples. The PCI-1710/1710HG generates an interrupt
when the FIFO is half full. This feature provides continuous high-
speed data transfer and more predictable performance on Windows
systems.

Chapter 1 General Information 3
On-board Programmable Counter
The PCI-1710/1710HG provides a programmable counter for generat-
ing a pacer trigger for the A/D conversion. The counter chip is an
82C54 or equivalent, which includes three 16-bit counters on a 10
MHz clock. One counter is used as an event counter for counting
events coming from the input channels. The other two are cascaded
together to make a 32-bit timer for a pacer trigger.
1.2 Features
• 16 single-ended or 8 differential analog inputs, or a combination
• 12-bit A/D converter, with up to 100 kHz sampling rate

2.1 Initial Inspection
Before installing the PCI-1710/1710HG, check the card for visible
damage. We have carefully inspected the card both mechanically and
electrically before shipment. It should be free of marks and in perfect
order upon receipt.
As you unpack the PCI-1710/1710HG, check it for signs of shipping
damage (damaged box, scratches, dents, etc.). If it is damaged or fails
to meet specifications, notify our service department or your local
sales representative immediately. Also, call the carrier immediately and
retain the shipping carton and packing materials for inspection by the
carrier. We will then make arrangements to repair or replace the unit.
2.2 Unpacking
The PCI-1710/1710HG contains components that are sensitive and
vulnerable to static electricity. Discharge any static electricity on your
body to ground by touching the back of the system unit (grounded
metal) before you touch the board.
Removethe PCI-1710/1710HG card from its protective packagingby
grasping the card's rear panel. Handle the card only by its edges to
avoid static discharge which could damage its integrated circuits.
Keep the antistatic package. Whenever you remove the card from the
PC, protect the card by storing it in this package.
You should also avoid contact with materials that hold static electricity
such as plastic, vinyl and styrofoam.
Check the product contents inside the packing. There should be one
card, one CD-ROM, and this manual. Make sure nothing is missing.

2.3 Installation Instructions
The PCI-1710/1710HG can be installed in any PCI slot in the
computer. However, refer to the computer user's manual to avoid any
mistakes and danger before you follow the installation procedure
below:
1. Turn off your computer and any accessories connected to the
computer.
Warning! TURNOFF yourcomputerpowersupply whenever
you install or remove any card, or connect and
disconnect cables.
2. Disconnect the power cord and any other cables from the back of
the computer.
3. Remove the cover of the computer.
4. Select an empty 5 V PCI slot. Remove the screw that secures the
expansion slot cover to the system unit. Save the screw to secure
the interface card retaining bracket.
5. Carefully grasp the upper edge of the PCI-1710/1710HG. Align the
hole in the retaining bracket with the hole on the expansion slot and
align the gold striped edge connector with the expansion slot socket.
Press the card into the socket gently but firmly. Make sure the card
fits the slot tightly.
6. Secure the PCI-1710/1710HG by screwing the mounting bracket to
the back panel of the computer.
7. Attach any accessories (68-pin cable, wiring terminal, etc.) to the
card.
8. Replace the cover of your computer. Connect the cables you
removed in step 2.
9. Turn the computer power on.

3.1 Overview
Correct signal connections are one of the most important factors in
ensuring that your application system is sending and receiving data
correctly. A good signal connection can avoid much unnecessary and
costly damage to your valuable PC and other hardware devices. This
chapter will provide some useful information about how to connect
input and output signals to the PCI-1710/1710HG card via the I/O
connector.
3.2 I/O Connector
The I/O connector for the PCI-1710/1710HG card has 68 pins that you
can connect to 68-pin accessories with the PCL-10168 shielded cable.
Note! ThePCL-10168 shieldedcableis speciallydesigned
forthe PCI-1710/1710HGforreducing noisein the
analog signal lines. Its wires are all twisted pairs,
and the analog lines and digital lines are seperately
shielded,providing minimalcross talk between
signals and the best protection against EMI/EMC
problems.
