External cabling
: Cabling outside the case.
Figure 4-3: Inner and Internal Cabling Variants
1 = Cabling of short cPCI modules to the adapter interface
2 = Cabling of short cPCI modules to the analog bus
3 = Analog bus
4 = Cabling of short cPCI modules to rear connectors
5 = Cabling analog bus to rear connectors
6 = PXI Local Bus
7 = Cross-wiring of short cPCI modules to each other at the front
These various cabling options provide a number of benefits:
●
Separating the adapter side (front) from the infeed of external devices (rear) cre-
ates a clear signal concept with no cross-wiring outside the case.
●
Wiring is kept safe from inadvertent changes.
●
The simple inner cabling concept means that modules can be quickly replaced dur-
ing servicing. Bus connections are used instead of cable connections.
