J20 IrDa
Pin Signal
Pin 1 = VCC 5V
Pin 3 = IR RX
BIOS settings:
You have to enable the UART A of the GeodeLX in the bios setup:
F1 -> Motherboard device configuration -> I/O configuration:
UART port A = enabled
-
UART mode = SIR/CIR
-
ATTENTION !
Do never set the UART A mode to "Serial – 16550 compatible" or "Extended" if a IrDa diode is con-
nected to the J20. Otherwise the diode will be destroyed!
