For Your Safety
Your new PEP 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 PEP product, you are requested to conform with the fol-
lowing guidelines.
High Voltage Safety Instructions
Special Handling and Unpacking Instructions
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 piggy-
backs, ROM devices, jumper settings etc. If the product contains batteries for RTC or memory
back-up, ensure that the board is not placed on conductive surfaces, including anti-static plas-
tics or sponges. They can cause short circuits and damage the batteries or conductive circuits
on the board.
Warning!
All operations on this device must be carried out by sufficiently skilled
personnel only.
Caution, Electric Shock!
Before installing your new PEP product into a system always ensure
that your mains power is switched off. This applies also to the instal-
lation 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.
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.

ranty.
If the customer’s eligibility for warranty has not been voided, in the event of any claim, he may
return the product at the earliest possible convenience to the original place of purchase, togeth-
er with a copy of the original document of purchase, a full description of the application the
product is used on and a description of the defect. Pack the product in such a way as to ensure
safe transportation (see our safety instructions).
PEP provides for repair or replacement of any part, assembly or sub-assembly at their own dis-
cretion, or to refund the original cost of purchase, if appropriate. In the event of repair, refunding
or replacement of any part, the ownership of the removed or replaced parts reverts to PEP
Modular Computers, and the remaining part of the original guarantee, or any new guarantee to

1. Introduction
1.1 System Overview
The CompactPCI board described in this manual operates with the PCI bus architecture to sup-
port additional I/O and memory-mapped devices as required by various industrial applications.
For detailed information concerning the CompactPCI standard, please consult the complete
Peripheral Component Interconnect (PCI) and CompactPCI Specifications. For further informa-
tion regarding these standards and their use, visit the homepageof the PCI Industrial Computer
Manufacturers Group (PICMG).
Many system relevant CompactPCI features that are specific to PEP Modular Computers Com-
pactPCI systems may be found described in the PEP CompactPCI System Manual. Please re-
fer to the section “Related Publications” at the end of this chapter for the relevant ordering
information.

• Common information that is applicable to all system components, such as safety infor-
mation, warranty conditions, standard connector pinouts etc.
• All the information necessary to combine PEP’s racks, boards, backplanes,power supply
units and peripheral devices in a customized CompactPCI system, as well as configura-
tion examples.
• Data on rack dimensions and configurations as well as information on mechanical and

1.2 Product Overview
The CP381 Digital Input controller is part of a comprehensive concept whose goal is to provide
CompactPCI system integrators with a complete range of CompactPCI I/O products which in-
clude the functions of analog input, analog output, digital input and digital output implemented
on separate individual boards. This concept ensures the maximum degree of system design
flexibility thus allowing for the efficient and effective usage of available resources.
The CP381 is a 3U/4HP CompactPCI board which provides 30 digital input channels and has
some useful optional features (such as debouncing, input event detection, input capture and-
compare).
The basic functions of this board are to provide interfacing to the application (process), perform
D/D signal conversion, and to make the raw digitized data available for further processing.
The major components involved in these processes are the front end (process side) Signal
Conditioning and the Digital Input Process and Communications (DIProcomm) Controller which
is realized within a Field-Programmable Gate Array ( FPGA). The DI ProComm controller is de-
signed to provide effective and efficient control of digital input signal conditioning as well as in-
terfacing with the CPCI system controller.
The following table provides a quick overview of the CP381 board.
