1: This is a simple wireless remote control module, no additional instructions.

2 : VT output high (5V TTL level) when signal received;

3: D1 D2 D3 D4 four data pins corresponding to four buttons on the remote control, for example: when the A button on the remote control is pressed, D1 high output, etc.

4: VT and D1-4 pins are 5V TTL pin 10MA maximum energy output current can drive the MCU port or LED lights . 
 
 
Inter-locking (Latch): 4-way relay each other to switch, when relay A  is working and locked  ,  relay B C D corresponding to switch off; when B is working and locked , corresponding relay A C D swith off ; Only 1 relay is on among 4 relays A B C D;
 
Non-locking  type (Momentary): Press A and hold it , then A is on.Same as Relay B C D ;
 

Self-lock type (Toggle): 4 chanels opens and closes independently, 4 chanels can work together ,they don’t affect each other . press A button, A relay of work and locked, press again then  disconnected; Same as B C D .

 

 
User guide :
1: Learing ID : Press learning button , LED is on and beginning to learn ;after learning , LED will flash for a while .Then LED will keep being on to learn the next remote. If perss the learned remoter controller , auto-quit learning within 10 seconds;
 
2: Delete ID : Keep pressing learning button for 5 seconds , LED will be on and enter deleting . LED off means finishing deleting;
 
3: Antenna with a soft wire or other hard metals (such as whip antenna), try to straighten. Do not go near metal objects;
 
4: Power supply voltage requires stable and low ripple factor, multi-level filtering (such as adding beads, inductors, capacitors, etc.);
