Documentation

How it works

1. 1On power-up, RUN lights up and the unit returns to its last mode, AUTO or LOCAL.
2. 2In AUTO, the Modbus master controls each light (registers from 4001) and reads its state (registers from 3001).
3. 3To switch to LOCAL, ENTER is held for 5 seconds; the keys select the light and its state.
4. 4The identifier is changed by powering up with the increment and decrement keys pressed.
