1.2 Board Overview
1.2.1 Board Introduction
The CP382 is a digital output board which provides twenty-four output channels grouped into
three clusters of eight channels each. The major components involved are the front end High
Side Driver switches (HSD = High Side Driver switch), output signal optoisolation, and the Dig-
ital Output Process and Communications (DO ProComm) controller which is realized within a
Field-Programmable Gate Array (FPGA). The DO ProComm Controller is designed for effec-
tive and efficient control of the digital output signals as well as providing interfacing with the
CPCI system controller.
Digital output requests from the System Controller are processed accordingly by the DO Pro-
Comm controller and are then routed to the HSD’s which in turn create the actual digital output
utilizing 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 High Side Driver 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.
1.2.2 Board Specific Information
Specific board components involved in the digital output process:
• One front panel connector (62-pin, female, D-sub type)
• 6 HSD switches (4 channels per switch, 2 switches per cluster)
• Optoisolation for each output channel
• One FPGA (the DO ProComm controller)
• One CompactPCI bus connector (J1, board to backplane, 132-pin, female, six row)
• One EEPROM (CapROM)
1.3 System Relevant Information
The following system relevant information is general in nature but should still be considered
when developing applications using the CP382.
Table 1-2: System Relevant Information
SUBJECT INFORMATION
System Configuration The CP382 operates with a system clock frequency of 33 MHz.
The maximum number of CP382’s which may be installed in any one system
depends on the system configuration.
Master/Slave Functionality The CP382 functions only as a slave. As such it requires a system master for
servicing.
System Controller The CP382 cannot function as a system controller.
Voltage Source The voltage source for the CP382 must conform with the specifications set
forth in this manual.
