CompactPCI Bus Connector

Figure 2-10: CompactPCI Connectors J1-J5
The complete CompactPCI connector configuration comprises five
connectors named J1 to J5. Their functions are as follows:
• J1/J2: 32-bit CompactPCI interface with PCI bus signals, arbi-
tration, clock and power
• J3, J4 and J5 have rear I/O interface functionality
• J4 only has optional rear I/O functionality from the PMC module
The CP6500-V is designed for a CompactPCI bus architecture. The
CompactPCI standard is electrically identical to the PCI local bus.
However, these systems are enhanced to operate in rugged industrial
environments and to support multiple slots.
2.2.20.1 CompactPCI Connector Keying
CompactPCI connectors support guide lugs to ensure a correct polar-
ized mating. A proper mating is further assured by the use of color
coded keys for 3.3V and 5V operation.
Color coded keys prevent inadvertent installation of a 5V peripheral
board into a 3.3V slot. The CP6500-V board is a 5V version. Back-
plane connectors are always keyed according to the signaling (VIO)
level. Coding key colors on J1 are defined as follows:

To prevent plugging a 5V CP6500-V version into a 3.3V VI/O back-
plane slot, a blue key is installed in J1.
To prevent plugging the CP6500-V into an H.110 backplane slot, a
brown key is installed in J4.
