6.4. Serial port
The microcontroller programming serial port 1 is connected to the RS232 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.

An additional serial port is connected to the application headers.
6.5. LCD Module
An LCD module is supplied to be connected to the connector J11. This should be fitted so that the LCD module lies over J3. Care should be
taken to ensure the pins are inserted correctly into J11.The LCD module uses a 4 bit interface to reduce the pin allocation. No contrast
control is provided; this is set by a resistor on the supplied display module. The module supplied with the RSK only supports 5V operation.
Table 6-5 shows the pin allocation and signal names used on this connector.
