I bought 2 sets of your wireless relay switches but cannot get them to work. I have read through all documentation but since it was written by someone in China it’s very unclear. I have both transmitter and receiver powered up and 5VDC going to the “enable transmitting” terminal but no relay on the receiver is responding.
I have the transmitter and receiver all connected to 5 VDC (transmitter) and 12VDC (receiver) properly. I want to use only one of the two channels and for now I will only be using one set so the address pins probably do not need to be moved.
Can you tell me what pins (1, 2, 3, 4) should be in place to transmit only to one of the relays? Also, none of the encoding pins are installed, do they need to be? As I said I have downloaded all PDF documentation but none is written in clear English so it is mostly useless so please don’t direct me to the same downloads.
You have two wires connected on the TE pin (a green and a grey wire). Is the grey wire GND ? (please see the attached picture 1). If so, you are shorting 5V and GND because the two pins are connected and are both TE transmitting enable pin (please see picture 2). In this case you will have to desolder the grey wire and hope that this didn’t damage any component on the transmitter board.
To select the relay you want to activate, first remove all the jumpers on pin 1,2,3 and 4 then connect pin 2 or 4 to 5V. If you want to activate both relays, you will have to connect both pin 2 and 4 to 5V (please see picture 3)
Both of the wires at TE are from the positive terminal of my 5 volt transformer as is the power feed to the board and the ground is in the right place too. I tried installing jumper #2, fired both transmitter and receiver boards up but still no relay closes. Any other thoughts? Thanks.
Here’s a complete look at my wiring. I think it’s all correct but still I can’t get any relay response from the receiver board. I have verified that the receiver is getting the correct input voltage too. Thanks. Kerry
Try to remove the jumper on pin 2 and connect the second pin to 5V (like in the picture attached).
You can also remove one 5V wire from the TE enable pin and keep only one.
I soldered a wire right to the jumper, connected it to the +5VDC and success! Thank you very much for your help. I am using this in conjunction with a motion sensor and contactors on the receiving end to turn 12, 200 watt LED lights on in my store only when customers come in, should save $1000.00 year. Thanks again. Kerry
