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.

HW schematics

le WL 500 GP a 2 port séries (connecteur SV1) on en utilise :

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
