====== Serial Port ======
Serial is located on pin soldering points (ready for soldering of 8-pin connector for use with detachable cable) on the centre of the right upper side (viewing from front panel) under ventilation holes. At right from these points, you can see printed pin descriptions:
|RESET |    |
|GND   |3.3V_OUT|
|UART_TX1    | UART_TX0   |
|UART_RX1    | UART_RX0   |
Pin 1 (with the square solder pad) is RX0.

These serial ports use TTL levels. You need an additional voltage convertor to get a standard serial port. The parameters are 115200 baud and 8-n-1.

le WL 500 GP a 2 port séries (connecteur SV1) on en utilise :
  * un pour le driver 1W  
  * un pour un terminal


la conversion de niveau est simplement faite avec un pont diviseur 

le port SV2 sert a brancher de l'instrumentation pour espionner les lignes séries
