CP383 Preface
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
Warning!
All operations on this device must be carried out by sufficiently skilled
personnel only.
Caution, Electric Shock!
Before installing your new Kontron product into a system always
ensure that your mains power is switched off. This applies also to the
installation of piggybacks.
Serious electrical shock hazards can exist during all installation,
repair and maintenance operations with this product. Therefore,
always unplug the power cable and any other cables which provide
external voltages before performing work.
Special Handling and Unpacking Instructions
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.
P R E L I M I N A R Y
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 board 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 board.

Introduction CP383
1.2 Product Overview
The CP383 Digital Input and Digital Output Controller is part of a comprehensive concept to
provide CompactPCI system integrators with a complete range of CompactPCI I/O products
which include the functions of analog input, analog output, digital input, and digital output implemented as separate individual boards. This concept ensures a maximum degree of system
design flexibility thus allowing efficient and effective usage of available resources.
As an enhancement to this concept, the CP383 combination board has been designed to implement digital input and digital output functions on one board. The CP383 is a 3U / 4HP CompactPCI board which provides 32 channels that are organized into 3 separate clusters, one
cluster consisting of 16 channels for digital input, and two clusters consisting of 8 channels
each for digital output.
The basic functions of this board are on the one hand to provide interfacing to the application
(process), perform D/D signal conversions, and to make raw digitized data available for further
processing via the 16 input channels, and on the other hand to provide a large number of automatically controlled, flexible digital outputs within a ruggedized board equipped with features
for electrical protection, such as overtemperature thermal shutdown, and overcurrent and undervoltage protection via the output channels. Each of the two digital output clusters can be
configured for its own external supply voltage as required.
The major components involved in these processes are the front end (process side) signal conditioning (digital input and digital output), the High Side Driver (HSD) switches (digital output),
and the Digital Input and Output Process and Communications (DIO ProComm) Controller
which is realized in a field-programmable gate array (FPGA). The DIO ProComm Controller is
designed to provide effective and efficient control of the digital input and output processes as
well as interfacing to the CPCI system controller.

Introduction CP383
1.3.1.1 Board Introduction - Digital Input
The digital input cluster consists of 16 input channels. The source of the digital inputs must be
a voltage generator. The board accepts only differential voltages up to a maximum of +30V. The
input current is limited to 5 mA over the specified input voltage range.
Input signal processing begins with the presentation of the signal to the front panel connector.
Signal conditioning prior to the signal reaching the DIO ProComm Controller includes: overvoltage protection, ESD, low-pass filtering, inverse polarity protection, defined low and high ranges, current limitation, optoisolation and buffering.
After signal conditioning, all parallel digital data is routed to the DIO ProComm Controller,
where the control and status registers are set.
The DIO ProComm Controller controls the interface with the CompactPCI bus and the dedicated software.
Input signal types and ranges are as follows:
• Edge frequency:
• Maximum 10 kHz
• Voltage Ranges:
• High range: +11V to +30V (+24V nominal)
• Low range: -3V to +5V
• Channel isolation
• The input channels are isolated from the system side and do not share common GND
or VCC.
• Differential input
Output data
The following outputs are routed from the DIO ProComm Controller to the CompactPCI bus:
• Input data for all channels as a 32-bit value (each bit from 0 - 15 represents the status of
• Flag set information from the control and status registers
• Interrupts

1.3.1.2 Board Introduction - Digital Output
The two digital output clusters consist of 8 output channels each. The digital output requests
from the system controller are processed accordingly by the DIO ProComm Controller and are
then routed to the HSD switches, which in turn perform output signal conditioning using the external supply voltage as the power source.
An external reset input is provided to simultaneously switch off all the outputs per cluster and
sets all the HSD switches to open. Each cluster has its own separate reset signal input.

This reset can be used by the application to keep the inputs low after a fault condition.
1.3.2 Board Specific Information
Specific board components involved in the digital output process:
• One front panel connector (62-pin, female, D-sub type)

1.4 System Relevant Information
The following system relevant information is general in nature but should still be considered
when developing applications using the CP383.
Table 1-2: System Relevant Information
SUBJECT INFORMATION
System Configuration The CP383 operates with a system clock frequency of 33 MHz.
The number of CP383s which can be installed in any one system depends
solely on the number of carrier interfaces available.
Master/ Slave Functionality The CP383 functions only as a slave. As such it requires a System Master for
servicing.
System Controller The CP383 cannot function as a system controller.
Digital Inputs Digital inputs to the CP383 must be conform to the inputs specifications set
forth in this manual for the CP383. In most cases, some form of signal conditioning will be required on the process side prior to a signal being presented
to the CP383.
Digital Outputs The voltage source for the digital outputs of CP383 must conform with the
specifications set forth in this manual.
1.4.1 System Configuration
When implementing applications, precautions must be taken to ensure that the input signals
presented to the CP383 comply with the specifications set forth in this manual. For this reason
it will be necessary for most applications to provide signal conditioning prior to presenting the
digital inputs to the CP383.
The external supply voltage (VCC) used as the output voltage on the CP383, must be within
the specified supply voltage range. In addition, it should be a DC supply with good ripple and
noise characteristics. Please refer to chapters 4 and 5 for further information.

1.4.2 Driver Software
The CP383 is supplied with appropriate driver software which provides software interfacing
with the System Master.
