6.4. Serial port

The microcontroller programming serial port 1 is connected to the E8a connector. A serial port can be used by moving option resistors and

fitting the D connector. This can be connected to serial channel 1 if the E8a is disabled from using channel 1; or serial channel 0 while the

E8a is enabled.
