CompactPCI Bus Connector
Figure 2-12: CompactPCI Connectors J1-J5 (CON1-CON5)
The complete CompactPCI connector configuration comprises five
connectors named J1 to J5. Their functions are as follows:
• J1/J2: 64-bit CompactPCI interface with PCI bus signals, arbi-
tration, clock and power.
• J3 and J5 has rear I/O interface functionality.
• J4 only has optional rear I/O interface functionality.
The CP605 is designed for a CompactPCI bus architecture. The Com-
pactPCI standard is electrically identical to the PCI local bus. Howev-
er, these systems are enhanced to operate in rugged industrial
environments and to support multiple slots.
2.5.18.1 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 CP605 board is a 5V version. Backplane
connectors are always keyed according to the signaling (VIO) level.
Coding key colors are defined as follows:
To prevent plugging a 5V CP605 version into a 3.3V VI/O backplane
slot, a blue key is installed in J1.
To prevent plugging the CP605 into an H.110 backplane slot, a brown
key is installed in J4.
