2.1.3

System Interfaces

The CP381 provides interfacing capability for the following system elements:

•

Digital input

•

CompactPCI bus

•

Test and program development: JTAG/ISP

Digital 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.

2.1.4

Monitor and Control

Various monitor and control functions are available for the operation of the CP381. Two LED’s
are available for operator interaction. In addition, applications have access via the System Mas-
ter driver software to board specific registers.

2.1.5

Software

Driver software is available for the System Master application software.
