1. Introduction
Thank you for buying the Advantech PCI-1755. The PCI-1755 is a Ultra-Speed
32-ch Digital I/O card for the PCI bus. Its digital I/O channels are TTL-compatible
and use 74LS244 driver/buffer circuits to provide high output driving capacity.
These buffered circuits also require lower input loading current than regular TTL
circuits. The ultra speed data transfer functions fulfill your industrial or laboratory
application needs.
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-1755 card.
1.1 Features
nBus-mastering DMA data transfer with Scatter-Gather™technology
n32/16/8-bit Pattern I/O with start and stop trigger function, 2-mode
Handshaking I/O
nInterrupt handling capability
nOn-board active terminators for high speed and long distance transfers
nPattern match and Change state detection interrupt function
nGeneral-purposed 8-ch DI/O
The Advantech PCI-1755 offers the following main features:
PCI-Bus Mastering Data Transfer
The PCI-1755 supports PCI-Bus mastering DMA for high-speed data transfer. By
setting aside a block of memory in the PC, the PCI-1755 performs bus-mastering
data transfers without CPU intervention, freeing the CPU to perform other more
urgent tasks such as data analysis and graphic manipulation. The function allows
users to run all I/O functions simultaneously at full speed without losing data.
Special Shielded Cable for Noise Reduction
The PCL-101100 shielded cable is specially designed for the PCI-1755 for reducing
noise. Its wires are all twisted pairs, with input signals and output signals separately
shielded, providing minimal cross talk between signals and offering the best
protection against EMI/EMC problems.

Keeping the Output Values after System Reset
When the system is hot reset (power is not shut off), the PCI-1755 can either retain
the last digital output values, or return to its default configuration, depending on the
jumper setting. This practical function eliminates dangers and problems caused by
an unexpected system reset.
On-board FIFO Memory
The PCI-1755 provides an on-board FIFO (Fist In First Out) memory buffer, storing
up to 16K samples for digital input and 16K for digital output conversion.
Pattern Match Function
The PCI-1755 provides "Pattern Match" interrupt function for digital input channels.
The card monitors the state of digital inputs and compares them with a pre-set
pattern. When the received state matches the pre-set pattern, the PCI-1755 generates
an interrupt signal to system.
Change of State Function
"Change of State" interrupt function is provided at-- digital input channels. When
any signal line changes its state, the card generates an interrupt to the system to
handle this event.
Note:
. For detailed specifications of the PCI-1755, please refer to Appendix A,
Specifications.

application software to help fully utilize the functions of your PCI-1755 card:
Device Drivers (on the companion CD-ROM)
Advantech ActiveDAQ
Advantech GeniDAQ
Programming choices for DA&C cards: You may use Advantech application
software such as Advantech Device Drivers. On the other hand, advanced users can
use another option for register-level programming, although it is not recommended
due to its laborious and time-consuming nature.
Device Drivers
The Advantech Device Drivers software is included on the companion CD-ROM
at no extra charge. It also comes with all Advantech DA&C cards. Advantech’s
device drivers feature a complete I/O function library to help boost your
application performance. The Advantech Device Drivers for Windows
2000/95/98/ME/NT/XP works seamlessly with development tools such as Visual
C++, Visual Basic, Borland C++ Builder and Borland Delphi.
Register-level Programming
Register-level programming is reserved for experienced programmers who find it
necessary to write code directly at the level of device registers. Since register-level
programming requires much effort and time, we recommend that you use the
Advantech Device Drivers instead. However, if register-level programming is
necessary, you should refer to the relevant information in Appendix C, Register
Structure and Format, or to the example codes included on the companion
CD-ROM.
