D. CP-RIO3-01 Rear I/O Module
D.1 Overview
The CP302 family (CP302, CP302-PM and CP301) provides optional Rear I/O
connectivity for peripherals, a feature which may be particularly useful in specialised
CompactPCI systems. Some standard PC interfaces are implemented and assigned to
the front panel and to the rear connector J2.
When the Rear I/O module is used, the signals of some of the main board/front panel
connectors are routed to the module interface. Thus the Rear I/O module makes it much
easier to remove the CPU in the rack as there is practically no cabling on the CPU
board.
For the system Rear I/O feature a special backplane is necessary. The CPU board with
Rear I/O is compatible with all standard CompactPCI passive backplanes with Rear I/O
support on the system slot.
The CP-RIO3-01 Rear I/O provides the following interfaces, all signals are available via
jumper J2 .
