2.5.18.3 Rear I/O Configuration
Rear I/O interfaces are only available on the rear I/O version of the board.
Ethernet Interfaces
The Fast Ethernet interface is available on the front panel at CON6A and on the rear I/O inter-
face.
The combination of both front and rear I/O is not supported. The Fast Ethernet channel is de-
coupled, but enabled separately. It is not possible to operate both the rear and front I/O at the
same time. Switching over from front to rear I/O or vice versa is effected under BIOS control
without the need to plug/unplug Ethernet cables.
Gigabit Ethernet signals are available on the front panel connector and on the rear I/O interface
(PICMG 2.16 pinout). Configuration of the Gigabit Ethernet ports for rear I/O requires the in-
stallation of zero ohm resistors on the board in order to connect the signals to the J3 connector.
VGA CRT Interface
The VGA signals are available on both rear I/O and front I/O. In this configuration both interfac-
es are active. The 75 ohm termination resistor for the red, green and blue video signals are
equipped on the CP605
To enable the rear I/O port, the installation of zero ohm resistors is necessary.
Serial Interfaces COM1 and COM2
Only one interface may be used (rear I/O or front I/O). If the rear I/O interface is enabled, the
RS-232, RS-485, RS-422 drivers for the COM1 and COM2 port on the front I/O must be dis-
abled. The configuration can be accomplished via the BIOS.
Serial Interfaces COM3 and COM4
The serial interfaces COM3 and COM4 are only available via the rear I/O.
Parallel I/O Interface
The Parallel I/O Interface is only available via the rear I/O. In order to use the Parallel I/O Inter-
face as LPT interface, additional termination resistors (pull-up resistors) are required.
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
The two USB 1.1 interfaces are available only via the rear I/O.
Secondary EIDE Interface
Only one EIDE connector may be used at any one time through the same port; connecting both
EIDE devices to the CP605 baseboard and the rear I/O simultaneously will result in malfunction
and data loss.
Note ...
Both VGA ports are electrically identical and not separated. Do not connect
devices at both connectors (front I/O and rear I/O) at the same time.
