CLCD CLCD User Manual CLCD-216 & 420 Comfile CLCD Display Module On the back of the CLCD, a control board is attached. This control board receives CuNET (I2C) or RS232C signal and prints on the CLCD. DIP S/W CUNET RS232 5V RS232 GN D 5V N/ C RX SD A SC L 5V GN D CUNET GN 5V D 5V _R X CLCD can communicate using I2C or RS232. There are two RS232 connectors, one for 3pin 5V level signals and the other for 4 pin +/- 12V level signals. RS232 5V RS232 Use the DIP switch to set the I2C slave address. The 4th DIP switch is not used.

When connecting RS232, maximum baud rate settings for 12V(4 pin) level is 38400bps. For 5V level (3 pin), up to 115200bps can be used. The following is an example code when using the CB280 to connect to the CLCD module through CUNET protocol. When you execute this program, CLCD will display increment of numbers.
