The utility model discloses the automatic address-writing control circuit of a DMX512 protocol-based receiver, which comprises a 485 bus, and a controllable 2-way relay. The 485 bus comprises a 485A and a 485B. The 485A and a 485B are respectively connected with the controllable 2-way relay. The controllable 2-way relay is connected with a 485 AOUT and a 485 BOUT. The controllable 2-way relay is connected in parallel with a diode. The controllable 2-way relay is connected with a triode. The base electrode of the triode is connected with one end of a resistor. The other end of the resistor is connected with the NEXT-485 EN pin of a single-chip microcomputer in the receiver. According to the technical scheme of the utility model, the address of a lamp can be conveniently written by means of a hardware circuit connected to the receiver, so that the address writing function of lamps can be automatically realized. Therefore, the address writing efficiency of lamps is improved.
