DMX512 LED wall washer code writing precautions

When using the DMX512 led wall washer, you need to write code. DMX512 LED wall washer code writing precautions:

(1) Before writing code, connect the 4 ports A(D+), B(D-), PO, and GND on the code writer to the lamp firmly with copper wires, and check carefully. Note that when writing code, the AB line must also be connected to the B end of the code. The AB connection terminal of the code writer keeps A high and B low when writing code, and the IC must be in A high and B low state. Code can be written normally. This is one of the special features of IC error proofing.

(2) Before writing the code, test the RGB full brightness or the overall synchronous jump program to confirm whether there is any problem with the AB line. If the program is abnormal, don't write code. Check this question before writing code.

(3) After the code writing is completed, the IC driver blue light that receives the new address code is always on, and the new address code has taken effect at this time.

(4) After writing the code, use the dedicated test program (usually run point by point or brush color) that comes with the code writer to test to confirm whether the written code is completely correct.

(5) Codes should be written separately for LED digital tubes of different segments.
