32 Functional Description

CompactPCI J2 Pin Assignment

The CT-30 board provides Rear I/O connectivity for special

compact systems. Some standard PC interfaces are imple-

mented and assigned to the front panel and to the rear connec-

tor J2.

When the Rear I/O module is used, of some the signals of the

main board are routed to the Rear I/O 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 neces-

sary. The CT-30 with Rear I/O is compatible with all standard

CompactPCI passive backplanes with Rear I/O support on the

system slot.

The CT-30 Rear I/O provides the following interfaces:

X 32-bit/33 MHz CompactPCI (J1) and Rear I/O (J2)

X Two USB 2.0 ports

X Two Gigabit Ethernet ports without LED signals

X Three SATA ports

X Two COM ports

X Seven GPIOs

NOTE:

To support the Rear I/O feature a special backplane is neces-

sary. Do not plug a Rear I/O configured board in a non-system

slot Rear I/O backplane. Failure to comply with the above will

result in damage to your board.
