1.5 Jumpers and switches
JP1 is used for switching the serial interface from 1:1
to crossed connection. If you connect a 1:1 cable (like
the cable that comes with the kit) use the default
setting. If you connect a crossed cable set the jumper
to alternate setting.
JP3 is used for the LCD-LED backlight. If the jumper is
closed (1-2) the backlight will be ON. Remove the
jumper (=open) if backlight operation is not
necessary.
JP2 is used for I2C interface
JP4 is used as an output for the DAC or for PWM
