The LVK204-25 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, USB and RS422 communication models allow the LVK204-25 to be
connected to a wide variety of host controllers. Communication speeds of up to 115.2kbps for serial
2
protocols and 100kbps for I
C ensure lightning fast data display.
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 is available through a five by five matrix style keypad, and six general purpose outputs
provide simple switchable five volt sources. In addition, a Dallas One-Wire header provides a
convenient communication interface for up to thirty-two devices.
The versatile LVK204-25, with all the features mentioned above, is available in a variety of colour,
voltage, and temperature options to suit almost any application.
