GENERAL DESCRIPTION
1.1
Introduction
This specification describes the interface requirements and features of a 2 line Liquid Crystal Display (LCD)
, 30 characters wide. The characters are formed using a 8x18 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.
EIA-232C INTERFACE = IEE NO. L330-04X

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 12-29 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.
Figures 3 through 11 depict character sets used in this module.
