I have three Woods brand remote outdoor switches which are controlled by three different On/Off remotes which each have their own RF channels (labeled "A", "F", and "G"). Is there any way that I can manipulate the circuit board to change the RF channel on two of the three so that I can use one remote to control all three power supplies? I can post a pictures of both the circuit board of the power supply as well as the circuit board of the remote if that would be helpful. Thanks for any help anyone can provide.

 

I've added images of the two circuits boards. I thought the little blue component on each of them might be used to set the channel since it can be adjusted with a small screwdriver. I had no luck changing the RF channel by adjusting it, so it must be something else on the board which is controlling the RF channel? Maybe I am not adjusting the blue component correctly?

 

Can you post pictures of the bottom of both boards? They may be programmed by cutting traces.

 

As said, post pictures of the track side pcb, sounds like its a 'pcm' chip with programme links....

Sorry it took me a while to get these posted. Thanks for the help.

 

Bingo. See the gouged trace?

 

Yep, definately looks like the "cutting a trace method". A & F are hexadecimal numbers, "G" isn't.

It might be possible to spot a pattern from just an

GND-in-in-out-in-in-in-in-in pattern and letters and counting from the grounded pin.

I would imagine that you might have to cut a trace and put one back sort of thing.

You can scratch off the green to expose the copper at the ground plane or end of the small PCB trace. Then use a piece of wire wrap wire or even a strand or two from some stranded wire and solder the trace back and cut the required one or two The green is called solder resist. It might be better exposing it as it turns into the large blob of resist colored copper.

 

Yes pins1-8 are the programme links, looks like pin6 is cut, you just need to set the new one to the same links.

 

Thank you. I'll give it a shot.
