Our remote code is 20110120. As you can see from the picture:
L1 = 2
No solder = 0
1H = 1
The receiver inside of your sign needs to match the remote code, so you’ll have to look at the receiver inside of the sign that is attached to the GL_GMAN board. Here is a picture of the receiver for reference, you can see it’s also matching our 20110120 code.
