The DMG Radio Transmitter site requires a simple visual indication of the dual transmitter statuses.
The Arduino will measure simple 6x dry relay contacts from the transmitter logic and display messages directly onto a 4x20 character LCD display connected to the Arduino Mega 2560 controller.
The LCD Display will show pre-defined messages at set locations on the LCD display. The LCD display must be able to display any or all messages at once without scrolling.
Separate Arduino Mega 2560 digital inputs are to be used for the Status monitoring with an LCD & Digital input I/O refresh rate of at least 1 scan per ½ second.
Upon the Arduino Startup the LCD screen needs to display the following information for 4 seconds before returning to the main running routine.
