1/ Introduction
1.1. Board Overview
The CP347 serial communications controller board is a 3U CompactPCI board that implements the Exar XR17D154 PCI
controller with four UART interfaces.
External interfacing is supported via one 37-pin D-Sub serial I/O connector on the CP347’s front panel, providing the
signals for all four serial I/O channels that are individually programmable and support the RS232, RS422 and RS485
industry standards. Additionally, four pairs of LEDs indicate the four serial I/O channels’ receive and transmit data
transfer operations.
The CP347 is galvanic isolated between the system side and the serial I/O front panel D-sub connector for all four
channels.
In order to provide separate serial I/O channeling, it is possible to connect a front panel adapter to the 37-pin front
panel connector. This adapter terminates on the user side with four male 9-pin D-Sub connectors, one per serial I/O
channel.
The board is offered with various Board Support Packages including Windows®, VxWorks® and Linux®operating
systems. For further information concerning the operating systems available for the CP347, contact Kontron Support.
