Servida Products      LCD 2x20, LCD 4x20, LED 2x20, LED 4x20

The LCD2X20 and LCD4X20 are character-oriented LED-back lit LCD dot matrix displays built for the AniLink™ Network. The LED2X20 and LED4X20 have luminescent characters in a vacuum type display. These units are intended for use as part of an operator interface for Servida Motors.

The displays are divided into lines, each line capable of displaying twenty characters. The LCD2X20 uses a two line display, while the LCD4X20 is built around a four line display. Available characters include 96 ASCII and Japanese characters and 32 special symbols.
Each unit takes up 1 AniLink™ port address (8 max).
The AniLink Network is a proprietary serial-based high-speed network based on I2C technology. The Servida LCD and LED units include the controller LSI, MPU and network support chips necessary for plug-in operation. The Servida Motor command set supports both high and low level commands for addressing the displays.
An entire user interface can be built around a Servida Motor by using other inputs for push buttons or by using an encoder-pot with Servida Motors equipped with an external encoder input. Sample code for such applications is available from Servida. Both text and data can be printed to the displays.
