2. Functional Description

The following chapters present more detailed, board level information about the CP383 Digital

Input and Digital Output Controller whereby the board components and their basic functionality

are discussed in general.

2.1 General Information

The CP383 is comprised basically of the following:

• Digital input signal conditioning

• Digital output signal conditioning (High Side Driver switches), common GND and VCC for

each output cluster

• Optocouplers

• DIO ProComm Controller

• Controls digital inputs and outputs

• Provides interfacing to the CompactPCI bus

• System interfaces for:

• Front panel

• 16 channels of digital input and 16 channels of digital output

• External supply connection for each digital output cluster

• External hardware reset for each digital output cluster

• One 62-pin, female, 3-pin row, D-sub connector (CON2)

• CompactPCI bus

• 132-pin, female, 6-pin row connector (CON1)

• CompactPCI specification

• Onboard memory: Capability EEPROM (CapROM)

• Monitor and Control

• Two operational status LEDs for user-defined purposes

• External reset

• Output failure indicators

• Software

2.2 Board Level Interfacing Diagram

The following figure demonstrates the interfacing structure between the internal processing

modules of the CP383 and other major CP383 system components. Where CP383 system el-

ements have common interfacing they are grouped into a block. Interfacing common to only

one element of a block is indicated with a direct connecting line. The interfacing lines are shown

in white where they are onboard and in black for board external interfacing.
