· output unit - elements controll LED segments
· main unit - based on AT89C51 microcontroller - reads coded data and
display it on LED displays
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).
Datatransfer with controller is realised with RS-485 port. It use standard
MODBUS RTU protocol.
