    LED directive definition
    1. POWER: power status indication, "bright" power supply is normal
    2. COMM: RS-485 communication indicates that "flash" is sending and receiving data
    3. DI0~DI7: digital input indicator, "bright" digital input is 1
    4. RO0~RO3: relay output indication, "bright" relay RO and COM closure
    Using the default communication parameters
    When you forget module communication (ID, baud rate, parity bit), the INIT and VS- pins are short circuited, module electrifying, The communication parameters of the module are (9600, N, 8, 1), ID is 1.INIT and VS- pin is disconnected, module using parameters set by the user, default parameters for the module (9600, N, 8, 1), ID is 1.
