External Control LCD3215/LCD4215



1. Application

This document defines the communicat ions 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.

Ex.) When H Freq is '1''2''A''9' (31h, 32h, 41h, 39h), it means 47.77kHz.

5.5.3 NULL Message

0:Negative Vertical sync polarity.

STX

The NULL message returned from the monitor is used in the following cases;


