1. Application

 

 

This document defines the communications method for control of the LCD3215/LCD4215 when using an 

external controller

.

 

 

2. Connectors and wiring 

 

Connector: D-Sub 9-pin 

 Cable: Cross (reversed) cable or null modem cable 

 

 

 
 

3. Communication Parameter

 

   

(1) Communication system Asynchronous 

  (2) Interface   

RS-232C 

(3) Baud rate   

9600bps 

(4) Data length 

8bits 

(5) Parity 

 

None 

(6) Stop bit 

 

1 bit 

(7) Communication code  ASCII 

 

3.1 Communication timing 

The controller should wait for a packet interval before next command is sent. 
The packet interval needs to be longer than 600msec for the LCD3215/LCD4215.
