2.1.3 ADC ProComm Controller
Within the CP371, the ADC ProComm controller is responsible for supervising and controlling
the analog data acquisition process and providing communications with the CompactPCI sys-
tem master. Applications address the CP371 through its software driver interface within the
system master whereby the controller accepts requests from the driver, executes them accord-
ingly, and supervises the analog to digital conversion process. Data from the ADC is processed
through the ADC ProComm controller and then made available to the system master.
In addition to the raw digitized analog data, the ADC ProComm controller also has access to
board calibration data for gain and offset error correction. This data is available to the applica-
tion through the driver software.
2.1.4 System Interfaces
The CP371 provides interfacing capability for the following system elements:
• Analog input
• CompactPCI bus
• Test and program development: JTAG/ISP
Analog input interfacing is achieved 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.
2.1.5 Monitor and Control
Various monitor and control functions are available for the operation of the CP371. Two LED’s
are available for operator interaction. In addition, applications have access via the System Mas-
ter driver software to board specific registers.
2.1.6 Software
Driver software is available for the System Master application software.
2.2 Board-Level Interfacing Diagram
The following figure demonstrates the interfacing structure between the internal processing
modules of the CP371 and other major CP371 system components. Where CP371 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 on board and in black for board external interfacing.
