Chapter 1 Introduction
Thank you for buying the Advantech PCI-1761. The Advantech PCI-
1761 is a 8-channel relay actuator and 8-channel isolated digital input
card for the PCI bus.
Its eight on-board SPDT relays are ideal for applications such as device
ON/OFF control or small power switched. For easy monitoring, each
relay is equipped with one red LED to show its ON/OFF status.
The PCI-1761's eight optically-isolated digital input channels are ideal
for digital input in noisy environments or with floating potentials.
The following sections of this chapter will provide further information
about features, installation guide, together with some brief information on
software and accessories for the PCI-1761 card.
1.1 Features
❏ 8 relay output channels and 8 isolated digital input channels
❏LED indicators to show activated relays
❏4 Form A-type and 4 Form C-type relay output channels
❏Output status read-back
❏Keep relay output values when hot system reset
❏High-voltage isolation on input channels (3,750 VDC)
❏High ESD protection (2,000 VDC)
❏High over-voltage protection (70 VDC)
❏Wide input range (10 ~ 50 VDC)
❏Interrupt handling capability
❏Board ID
The Advantech PCI-1761 offers the following main features:
Robust Protection
The PCI-1761 digital input channels feature a robust isolation protection
for industrial, lab and machinery automation applications. It durably
withstands voltage up to 3,750 VDC, preventing your host system from

Chapter 1 Introduction
PCI-1761 User’s Manual 2 Advantech Co., Ltd.

any incidental harms. If connected to an external input source with surge-
protection, the PCI-1761 can offer up to a maximum of 2,000 VDC ESD
(Electrostatic Discharge) protection. Even with an input voltage rising up
to 70 VDC, the PCI-1761 can still manage to work properly albeit only for
short period of time.
Wide Input Range
The PCI-1761 has a wide range of input voltage from 10 to 50 VDC, and
it is suitable for most industrial applications with 12 VDC, 24 VDC and 48
VDC input voltage.
Reset Protection Fulfills Requirement for Industrial Applications
When the system has undergone a hot reset (i.e. without turning off the
system power), the PCI-1761 can either retain outputs values of each
channel, or return to its default configuration as open status, depending
on its on-board jumper setting. This function protects the system from
wrong operations during unexpected system resets.
Plug-and-Play Function
The PCI-1761 is a Plug-and-Play device, which fully complies with PCI
Specification Rev 2.2. During card installation, there is no need to set
jumpers or DIP switches. Instead, all bus-related configurations such as
base I/O address and interrupt are automatically done by the Plug-and-
Play function.
Board ID
The PCI-1761 has a built-in DIP Switch that helps define each card's ID
when multiple PCI-1761 cards have been installed on the same PC chas-
sis. The board ID setting function is very useful when users build their
system with multiple PCI-1761 cards. With correct Board ID settings,
you can easily identify and access each card during hardware configura-
tion and software programming.
Note:
✎For detailed specifications of the PCI-1761, please refer to Appendix
A, Specifications.

1.3 Installation Guide
Before you install your PCI-1761 card, please make sure you have the
following necessary components:
❏PCI-1761 card
❏PCI-1761 User's Manual
❏Driver software Advantech DLL drivers (included in the
companion CD-ROM
❏Wiring cable PCL-10137 (optional)
❏Wiring board PCLD-880, ADAM-3937 (optional)
❏Computer Personal computer or workstation with a
PCI-bus slot (running Windows 95/98/
NT/2000)
Some other optional components are also available for enhanced opera-
tion:
❏Application software ActiveDAQ, GeniDAQ or other third-
party software packages
After you get the necessary components and maybe some of the accesso-
ries for enhanced operation of your Multifunction card, you can then
begin the Installation procedures. Figure 1-1 provides a concise flow
chart to give users a broad picture of the software and hardware installa-
tion procedures.

1.4 Software Overview
Advantech offers a rich set of DLL drivers, third-party driver support and
application software to help fully exploit the functions of your PCI-1761
card:
zDLL driver (on the companion CD-ROM)
zLabVIEW driver
zAdvantech ActiveDAQ
zAdvantech GeniDAQ
Programming choices for DA&C cards: You may use Advantech applica-
tion software such as Advantech DLL driver. On the other hand,
advanced users are allowed another option for register-level program-
ming, although not recommended due to its laborious and time-consum-
ing nature.
DLL Driver
The Advantech DLL Drivers software is included on the companion CD-
ROM at no extra charge. It also comes with all the Advantech DA&C
cards. Advantech's DLL driver features a complete I/O function library to
help boost your application performance. The Advantech DLL driver for
Windows 95/98/NT/2000 works seamlessly with development tools such
as Visual C++, Visual Basic, Inprise C++ Builder and Inprise Delphi.
Register-level Programming
Register-level programming is reserved for experienced programmers
who find it necessary to write codes directly at the level of device regis-
ters. Since register-level programming requires much effort and time, we
recommend that you use the Advantech DLL drivers instead. However, if
register-level programming is indispensable, you should refer to the rele-
vant information in Appendix C, Register Structure and Format, or to the
example codes included on the companion CD-ROM.
