1 Introduction

Figure 1: LK162A-4T Display

The LK162A-4T is an intelligent alphanumeric liquid crystal display designed to decrease development

time by providing an instant solution to any project. In addition to the RS232, TTL and I2C protocols

available in the standard model, the USB communication model allows the LK162A-4T to be connected

to a wide variety of host controllers. Communication speeds of up to 115.2kbps for serial protocols and

100kbps for I

C ensure lightning fast display updates.

The simple command structure permits easy software control of many settings including backlight

brightness, screen contrast, and baud rate. On board memory provides up to forty custom characters

which can be saved within the unit and recalled for start screens, bar graphs or larger numbers.

User input on the LK162A-4T is available through a four key, integrated tactile keypad and three bi-

colour LEDs provide visual output. An additional two general purpose outputs on the back of the unit

provide simple, switchable five volt sources.

The versatile LK162A-4T, with all the features mentioned above, is available in a variety of colour,

voltage, and temperature options to suit almost any application.
