1 Introduction
Figure 1: GLK240128-25/GLT240128 Display
The GLK240128-25/GLT240128 is an intelligent graphic liquid crystal display engineered to quickly and
easily add an elegant creativity to any application. In addition to the RS232, TTL and I2C protocols
available in the standard model, USB and RS422 communication models allow the GLK240128-
25/GLT240128 to be connected to a wide variety of host controllers. Communication speeds of up to
2
115.2kbps for serial protocols and 100kbps for I
C ensure lightning fast text and graphic display.
The simple command structure permits easy software control of many settings including backlight
brightness, screen contrast, and baud rate. On board memory provides thirty-two kilobytes of
customizable fonts and bitmaps to enhance the graphical user experience.
User input on the GLK240128-25 is available through a five by five matrix style keypad or a resistive
touch overlay on the GLT240128. Six general purpose outputs provide simple switchable five volt
sources on each model. In addition, a versatile Dallas One-Wire header provides a communication
interface for up to thirty-two devices.
The versatile GLK240128-25/GLT240128, with all the features mentioned above, is available in a variety
of colour, voltage, and temperature options to suit almost any application.
