This area contains the main IO cabling to the other sections (video/power).
The connectors from left to right are
ID | Desciption | Notes |
---|---|---|
PL7 | Power | Grey and yellow are positive (+5V) , blue and red are Ground (0V) (Check this! dont rely - it may be different depending on the power board etc. etc.) |
PL8 | Video | Paird signal and grounds consisting of red,green,blue and composite sync1 |
PL4 | IR and LEDs2 | The first three ways of this connector are "Online" LED3, "Internet" LED and ground. The last two are signal and ground for the recived IR signal. |
PL1 | Serial | This is a modification! I have brought the first serial port from the Superio controller here. Unbuffered TTL async serial |
Interesting to note here the missing components, these were probably intended for audio output which seems to have been omited to save costs. The connector PL1 I have used for serial was probably intended as the audio out header. I intend to look at whats missing here and if it can be retro fitted.
Somewhat obscured by the cables in the picture is a small philips chip which is used to decode the IR stream from the remote in some manner. The decoded 9600 baud async serial is then presented to the second serial port on the SuperIo chip.
Another modification can be seen here in the bottom right hand corner of the picture. There are pads for a PS/2 type connector which has been populated on my board. This gives a conventional keyboard and mouse which has been very useful during experimenting with the board.
There's lots more to the site! A good place to start is the Main Page.
