The board is designed to accept a straight through RS232 cable.

6.5. LCD Module

The LCD module supplied with the RSK can be connected to the connector J6 for use with the tutorial code. Any module that conforms to

the pin connections and has a KS0066u compatible controller can be used. The LCD module uses a 4bit interface to reduce the pin

allocation. No contrast control is provided; this must be set on the display module.

Table 6-4 shows the pin allocation and signal names used on this connector.

The module supplied with the CPU board only supports 5V operation.
