Description
Universal self-learning remote control for gates, controls, alarms, cars, etc. It has 4 channels. It works on 315 MHz frequency. Allows you to make a spare transmitter in case of losing the original one.
Address code setting
Default address code is variable, if you want to use it with DFRobotRF Shield 315MHz for Arduino all jumpers must be removed. To do this you have to dismantle the remote control.
In order to program the remote control it is necessary to dismantle it. Individual rows of points correspond to grounding pin, address pin and high status pin. Each address pin can be set to high, low or variable. If it switches to L, it will go into low state, if it goes into high state on H, if it does not switch, it will remain in variable state. The encoding is similar to the RF overlays, they differ in the A0-A7 line order. A solder can be used to modify the address. The address on the receiver and remote control must be the same.
