Rear I/O Configuration - Kontron CP6500-V User Manual

CP6500-V

Rear I/O Configuration

Rear I/O interfaces are only available on the rear I/O version of the board.
Ethernet Interfaces
Fast Ethernet signals are available on the rear I/O interface (PICMG 2.16 pinout).
VGA CRT Interface
The VGA signals are available on both rear I/O and front I/O. The 75 ohm termination resistor
for the red, green and blue video signals are equipped on the CP6500-V.
To enable the rear I/O VGA port, configure the jumper J17.
Note ...
Both VGA ports are electrically identical and can be switched between front and
rear by configuring jumper J17 (open = front; closed = rear).
Serial Interfaces COM1 and COM2
Only one interface may be used (rear I/O or front I/O) for COM 1.
Note ...
Previous boards such as CP604 and CP605 used TTL signaling voltage for the
COM1 and COM2 rear I/O interfaces. Due to a new common Kontron rear I/O
pinout, the COM1 and COM2 ports can now be configured as RS232, RS422
and RS485 ports. Thus, neither RS232, RS424 nor RS485 buffers are now
required on the rear I/O. The signals can be connected directly to the D-SUB
connector.
Keyboard/Mouse Interface
The keyboard interface is available onboard and via the rear I/O. The combination of the on-
board and the rear I/O is not supported. The mouse interface is only available via the rear I/O.
USB Interface
Two USB interfaces are available via the rear I/O. The USB power comes from the baseboard
and it is protected by a self-resettable fuse.
Secondary EIDE Interface
Only one EIDE connector may be used at any one time through the same port; connecting both
EIDE devices to the CP6500-V baseboard and the rear I/O simultaneously will result in mal-
function and data loss.
Floppy Interface
The floppy interface is only available via the rear I/O.
PMC Rear I/O
The PMC Rear I/O pinout is optimized to connect the Kontron SCSI PMC board (PMC 261).
This module provides SCSI rear I/O support. Other PMC modules with rear I/O functionality can
also be used on the CP6500-V.
