1. Overview
1.1 Description of the CPCI-ASIO4 Board
Fig. 1.1.1: Block circuit diagram
The module CPCI-ASIO4 is a CompactPCI
®
board in Euro format. It has got four serial interfaces
which are electrically isolated against the CompactPCI bus and against each other.
The board is equipped with two DUARTs XR16C2852 that are compatible to the popular DUART
ST16C2552 and can therefore be controlled by standard operating system drivers for serial interfaces.
The four interfaces can be equipped with several piggybacks to realize your application-specific
requirements for a serial interface. You can choose between RS-232 (with hardware handshake),
RS-422, RS-482 or TTY. TTY can be run in passive or active mode. Only if the TTY active mode is
used, the four interfaces loose their electrical isolation because of the shared power supply for the
interfaces. The different interface types can be combined at one CPCI-ASIO4.
The connection of the interfaces is done at the front panel by RJ45 connectors.
LEDs display the actual state of each interface.
