GENERAL DESCRIPTION
1.1
Introduction
This specification describes the interface requirements and features of a 2 line Liquid Crystal Display (LCD) ,
6 characters wide. The characters are formed using a 16x16 dot matrix.
1.2
Application
This unit may be used as a console display which provides alphanumeric information that is easily readable in
high ambient light. It is ideal for point-of-sale terminals, office computers, and a wide range of business and
industrial equipment.

Description
This LCD is a self-contained multiplexed unit which provides a simple interface to a microprocessor system.
The display is available with one I/O connector and a choice of either EIA-232C or EIA-422A interfacing.
This unit consists of a liquid crystal display cell and a minimal amount of electronic hardware. All display
characters and control codes can be accessed in a 8-bit format. Primary complexity is contained within the
microprocessor software, which controls all display functions.
A single 11-29 volt power supply is required for operation. At +12VDC, total power is approximately .72 watts
and current is about 60mA.
Data is entered serially at 9600 Baud at rates determined by execution times.
The large characters are easily readable, even in direct sunlight and provide comfortable short or long-term
viewing.
Figure 3 depicts Chinese GB character set (16x16 dot) and Figure 4 depicts US-ASCII character (8x16 dot)
and Figure 5 depicts US-ASCII character (5x8 dot) used in this module.
