CP382 Introduction 1. Introduction 1.1 Product Overview The CP382 digital output controller has been designed to provide a large number of automatically controlled, flexible digital outputs within a ruggedised board equipped with features for electrical protection. The flexibility is due to the fact that the 24 channels provided are organised into 3 separate clusters of 8 channels each, allowing the user to configure up to 3 different voltages as required.
Introduction CP382 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 Digital Output Process and Communications (DO ProComm) controller which is realized within a Field-Programmable Gate Array (FPGA).
CP382 1.3.1 Introduction System Configuration The external supply voltage (VCC) used as the output voltage on the CP382, 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. 1.3.2 Driver Software The CP382 is supplied with appropriate driver software which provides software interfacing with the system master. 1.

CP382 2. Functional Description Functional Description The following sections present more detailed, board level information about the CP382 Digital Output controller whereby the board components and their basic functionality are discussed in general. 2.
Functional Description 2.1.1 CP382 High Side Driver Switches The High Side Driver switches (HSD switches) are able to drive inductive, capacitive or resistive loads. Diagnostic information for the system master and extensive use of electrical protection are among their main characteristics. The HSD switches (type L6376 manufactured by SGS THOMSON) constitute the most important part of the front end.
CP382 2.1.4 Functional Description System Interfaces The CP382 provides interfacing capability for the following system elements: • Front Panel connector • CompactPCI bus Digital outputs, external voltage, and external reset are routed via the CON2 connector. Interfacing to the CompactPCI bus is accomplished via the CON1 connector. Test and program development is supported by the CON3 connector. External supply each Cluster: The connection for the external supply (+24V DC [9.
Functional Description 2.2 CP382 Board Level Interfacing Diagram The following figure demonstrates the interfacing structure between the internal processing modules of the CP382 and other major CP382 system components. Where CP382 system elements 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.
CP382 Functional Description 2.3 System Interfaces 2.3.1 Digital Output Interface The digital output interface is routed through the CON2 connector. The following figure and table indicate the pin layout and pinout of this connector.

CP382 2.4 Functional Description CapROM EEPROM The CapROM is a 4 kBit (512 byte) EEPROM which provides the capability to store board control relevant information to allow software configuration of the CP382. 2.5 Monitor and Control (M/C) The front panel of the board is equipped with two LED’s for user defined purposes. One green (RUN) and one red (FAIL) have been placed on the front panel in anticipation of their most likely use.

CP382 4. Configuration Configuration This chapter provides information for configuring the CP382 board for operation. 4.1 Jumper Settings The CP382 does not have any jumpers which require configuring. 4.2 Digital Output Signal Properties In addition to the output signal type and its range, which have been specified in chapter 1, paragraph 1.3.1, system integrators must be aware of certain output configuration requirements for the CP382.
Configuration 4.2.3 CP382 Channel Connection The following diagrams illustrate the external connection of the CP382 to the application.
CP382 Configuration Figure 4-3: External Reset Connection for One Cluster CON2 Supply Voltage External VCC 0 Ch 0 7 Ch 7 R Reset + V LOAD LOAD EXTGND CP382 External GND Note... The voltage source for each cluster is an external supply (in the range +9.5V to +35V DC). Therefore the GND reference for the digital output is the ground potential of this external voltage supply. Important...
Configuration CP382 4.3 Programming Interface 4.3.1 Access Control Logic (Address Decoder) All the resources of the CP382 are mapped within the 64 kB PCI memory address space which itself is set in the PCI configuration register BAR0. The port size of all local or backend registers is 32-bit by default. The address map of the registers is as follows.
CP382 4.3.2 Configuration Writing Output Data Table 4-2: Output Data Register Bit Map Bits Type 31-8 7-0 r/w r/w Default 0 0 Function Reserved Data, 8 bit digit Note... Output data is 8 bit (each cluster); this register is read/write enable. Table 4-3: Output Control Register Bits Type 31-2 1 0 r/w r/w r/w Default 0 0 1 Function Reserved irqen Reset Note... irqen is for diagnostic issuing an interrupt. The reset bit should be set to 0 to activate a cluster.
Configuration 4.3.3 CP382 Hardware Debug/Test Registers These registers are for internal test and debug only. The Common Status Register contains Logic-Version and PCB -Version. The Common Debug Register is a read/write register without any further functionality besides the front panel monitor and control LED’s.
CP382 4.3.4 Configuration Generating Interrupts A detected fail flag set in the register can trigger an interrupt. 1. Check if the board is the cause of the interrupt (General Interrupt Pending is set) 2. If yes, check the reason for the interrupt by reading the fail flag in the output status register 3. Reset the corresponding Flag by writing a 1 to a set status bit (fail). 4. Reset the boards’ IRQ by resetting the General Interrupt Pending Bit by writing a 1 to that status bit 5.
Configuration 4.3.5 CP382 Programming the Board Capability ROM The Board Capability ROM contains all the board data necessary to identify board, version, optional features, etc., and to setup the basic software. The BCR is implemented using a 4 KBit serial EEPROM of the type Microchip 93LC66. (The contents list of the BCR is not described here.

CP382 System Considerations 5. System Considerations 5.1 Introduction In addition to the basic specification requirements for the CP382 which have been addressed in chapter 4, system integrators need to be aware of the overall system environment and the application needs when designing the interfacing to the CP382. The following chapters address a number of more apparent considerations which should be addressed but certainly not all of the possible situations which may be encountered.
