Structure:
Y12WLED2 contains:
· output unit - elements controll LED segments
· main unit - based on AT89C51 microcontroller - reads coded data and display it on LED displays

Use:
Y12WLED2 displays any information by digits and others characters. It's a part of digital clocks or meters of temperature, pressure, voltage, frequency and others. It may also cooperate with data networks as display unit (measurment values and others).

Communication:
Datatransfer with controller is realised with RS-485 port. It use standard MODBUS RTU protocol.
