VGA Interface
The VGA signals are available on J2 when the board is ordered for Rear I/O configura-
tion. In this configuration both interfaces are active. The 75 ohm termination resistor for
the red, green and blue video signals are equipped on the CP302.
Serial Interface 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 drivers for the COM1 and COM2 port on the CP302 IDE2 module must be
disabled.
Keyboard/Mouse Interface
All PS2 connectors are electrically identical. Due to this it is not possible to use a mouse
at the front I/O and a second mouse at the Rear I/O port at the same time.
USB Interface
There are two independent USB interfaces available, one port is routed to the 4-pin front
I/O connector. This port may also be used on the Rear I/O interface. The second port is
only available on the Rear I/O connector.
