For Your Safety
Your new Kontron product was developed and tested carefully to provide all features necessary to ensure its
compliance with electrical safety requirements. It was also designed for a long fault-free life. However, the life
expectancy of your product can be drastically reduced by improper treatment during unpacking and installation.
Therefore, in the interest of your own safety and of the correct operation of your new Kontron product, you are
requested to conform with the following guidelines.
High Voltage Safety Instructions
As a precaution and in case of danger, the power connector must be easily accessible. The power connector is the
product’s main disconnect device.
Warning
All operations on this product must be carried out by sufficiently skilled personnel only.
Electric Shock!
Before installing a non hot-swappable Kontron product into a system always ensure that
your mains power is switched off. This also applies to the installation of piggybacks. Serious
electrical shock hazards can exist during all installation, repair, and maintenance operations
on this product. Therefore, always unplug the power cable and any other cables which
provide external voltages before performing any work on this product.
Earth ground connection to vehicle’s chassis or a central grounding point shall remain
connected. The earth ground cable shall be the last cable to be disconnected or the first
cable to be connected when performing installation or removal procedures on this product.
Special Handling and Unpacking Instruction
ESD Sensitive Device!
Electronic boards and their components are sensitive to static electricity. Therefore, care
must be taken during all handling operations and inspections of this product, in order to
ensure product integrity at all times.
Do not handle this product out of its protective enclosure while it is not used for operational purposes unless it is
otherwise protected.
Whenever possible, unpack or pack this product only at EOS/ESD safe work stations. Where a safe work station is not
guaranteed, it is important for the user to be electrically discharged before touching the product with his/her hands or
tools. This is most easily done by touching a metal part of your system housing.
It is particularly important to observe standard anti-static precautions when changing piggybacks, ROM devices, jumper
settings etc. If the product contains batteries for RTC or memory backup, ensure that the product is not placed on
conductive surfaces, including anti-static plastics or sponges. They can cause short circuits and damage the batteries
or conductive circuits on the product.

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.
Basic CP347 features are:
3U standard CompactPCI board form factor
High performance quad UART XR17D154
32-bit address and data bus
33 MHz system clock
Data rates of up to 115.2 kbps
Isolated (up to 2 kV between CompactPCI system and D-Sub front panel)
Four independent and individually configurable serial channels
RS232, RS422, and RS485 standards
Hardware selectable bus termination resistors (RS422/RS485)
One 37-pin dual-row D-Sub connector
Front panel Rx/Tx control LEDs
Windows®, Linux® and VxWorks® support

2/ Functional Description
2.1. General Information
The CP347 serial communications controller board is the realization of a low cost solution for industrial automation
communication purposes and represents the implementation of a serial communication controller board at the basic
OSI levels.
The main functions implemented on the CP347 board are the OSI Layer 2 data link control for RS232, RS422 and
RS485 communication purposes, and the OSI Layer 1 physical signal level adaptation for the RS232, RS422 and RS485
interfaces. The RS422 interface is realized for full duplex (4-wire) and the RS485 Interface is realized for half duplex
(2-wire) operation.
The physical layer adaptation (OSI Layer 1) of the TTL interface signals is realized independently for each channel via
corresponding on-board RS232, RS422/RS485 transceivers. Each of the four serial communication links are
configured individually for serial interface operation per hardware and software, including the serial line termination
for balanced serial communication.
2.2. Specifics
The OSI Layer 2 functions for serial communication are handled entirely by the Exar XR17D154 serial I/O controller.
This controller handles all the on-board serial communication tasks related to the OSI Layer 2, and also the data
transfer to the system host CPU over the CompactPCI bus.
For the various operation types, configuration of the serial communication links as well as serial line termination for
differential communication (RS422/RS485) is accomplished via hardware and software. The four serial I/O channels
are independent and can be configured individually for RS232, RS422/RS485 serial communication.
The data transfer operation of the serial channels is indicated at the front panel by four channel related pairs of LEDs,
for receive and transmit operations.
The communication functions including the RS232, RS422 and RS485 serial I/O functions are tied to the host system
via the standard PCI interface provided directly on the Exar XR17D154. Logical control of the CP347 serial
communication operation is accomplished via the Exar XR17D154 command and status registers that can be accessed
independently for each channel directly from the PCI side.
The CP347 serial I/O board is provided with a 37-pin D-Sub connector providing the signals for all four serial I/O
channels. In order to provide separate serial I/O channeling, a front panel adapter can be connected 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).
In addition, the CP347 is galvanic isolated between the system side and the serial I/O front panel D-Sub connector for
all four channels. This is accomplished with digital isolators using the iCoupler® technology. This is especially useful
in industrial environments, where voltage potential differences between the different transmission stations can
occur. Using this technology GND compensating currents can be avoided or minimized and the digital system side,
where expensive components such as CPU are located, is protected against noise transients.
An optional 1 Kbit EEPROM can be assembled to store the vendor’s ID and model number, and the sub-vendor’s ID and
product model number. If an EEPROM is assembled, the PCI controller reads four word data from the EEPROM’s first
four word locations and places those values into the PCI configuration space registers for chipset identification.
Additionally, the EEPROM can store proprietary data. If no EEPROM is assembled, the PCI controller uses the default
value of the PCI controller’s vendor and device ID. The IDs are stored in the configuration space for chipset
identification during the auto-configuration sequence.
2.3. Board Interfaces
The CP347 serial I/O board provides a 37-pin D-Sub connector with signals for all four serial I/O channels.
Additionally, in order to provide separate serial I/O channeling, it is possible to connect a front panel adapter to the
37-pin D-Sub front panel connector. This adapter terminates on the user side with four male 9-pin D-Sub connectors,
