Although the lamp is luminous, it does not accept the command of the controller?

1. Check whether the digital start address value and function options of lamps are correct;

2. Check whether the connection of communication control line is correct, the communication line is too long or has been interrupted;

3. Check whether the control equipment is invalid and whether the signal amplifier connected in series is invalid;

4. Check whether the communication line is too long or other equipment interferes with each other;

5. Optimize the wiring, shorten the length of control signal line, separate the high voltage and low voltage lines;

6. Add signal amplifier isolator;

7. The signal line adopts high quality shielded twisted pair (impedance characteristic is 75 Ohm);

8. Connect the signal terminal resistor at the end of the lamp.
