VK204-25

---

The VK204-25 is an intelligent alphanumeric vacuum florescent 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 VK204-25 to be connected to a wide variety of host controllers.  Communication speeds of up to 115.2kbps for serial protocols and 100kbps for I²C 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.
