Description
The PCA-8428/8429/8438/8439 are add-on PCI Express cards intended especially for
laboratory and industrial automation and measuring systems.
The PCA-8428/8429/8438/8439 cards provide especially these features:
• eight or sixteen isolated analog inputs equipped with 14-bit A/D converter
• with/without two isolated analog outputs equipped with 12-bit D/A converters
• three 8-bit bidirectional digital ports, software configurable as input or output
• IRQ logic with interrupt sources derived from rising or falling edge of each digital port
signal (i.e. 48 individually programmable interrupt sources) and internal timer
Available types and versions of cards:
PCA-8428
8 analog inputs, 2 analog outputs, three 8-bit DIO ports
PCA-8429
8 analog inputs, three 8-bit DIO ports
PCA-8438
16 analog inputs, 2 analog outputs, three 8-bit DIO ports
PCA-8439
16 analog inputs, three 8-bit DIO ports
PCT-84xx/LP
low-profile format card of PCA-8428, PCA-8429, PCA-8438 and PCA-8439
In the following text, unless otherwise stated, the designation PCA-84xx applies to all
types and versions of card.
1.2
General instructions for use
The PCA-84xx card is suitable for installation in either office or industrial computers that are
fitted with the PCI Express bus (Gen 1 compatible).
Cable types and their maximum length are described in paragraph 2.7 General data.
Caution:
The cards are designed for DAQ&C applications and may be used only according to the
manufacturer's recommendations and precautions given in this manual and other general
standards and terms and may be used only such a way, that its failure caused by any reason
will not be dangerous to any person or property.
1.3
Note on the contents of the manual
This manual contains all information related to card features, I/O connectors etc., but does
not include a description of installing and using drivers.
For information about drivers and programming check the dedicated documentation.
1.4
New firmware versions and customer´s firmware
The PCA-84xx card is based on a FPGA unified core providing implementation of PCI
Express bus and all peripheral circuitry, e.g. solution that gives maximum control and
supervision over full functionality. High concentration of control algorithms within FPGA
allows to add or modify functions without redesign the board (e.g. firmware with added
special custom features or a build completely new custom firmware).
A simple software utility for user-friendly firmware upgrade is available.
