I want to build a 4 channel RF remote control set into some of my equipment.
But i need to place several of these equipment in the same room next to each other.
is there any change they could mix up in controlling so the remote doesn’t match the correct receiver?
If you give each unit (remote+receiver) a unique code, they will not interfere with each other.
Please note that you cannot operate two or more transmitters simultaneously.
Also: leave at least 20cm between receivers, to avoid interference from one unit to another.
