Working Mode: Momentary Toggle Latched adjustable 

Pin No. Pin Name Instruction   

1 VT Output Status Indication   

2 D0 Data Output   

3 D1 Data Output   

4 D2 Data Output   

5 D3 Data Output   

6 5V Power+

Momentary .Toggle .Latched Adjusted by the Dot on the Receiver .

Momentary------------Press the Transmitter button A, the receiver relay A is ON, release button A; the receiver relay A is OFF, the same as B/C/D

Toggle---------------Press transmitter button A for 1 time , the receiver relay A is ON, press button A again, the receiver relay A is OFF, the same as B/C/D.

Latched------------------

Press transmitter button A, the receiver relay A is ON, the relay B/C/D is OFF.

Press transmitter button B, the receiver relay B is ON, the relay A/C/D is OFF.

Press transmitter button C, the receiver relay C is ON, the relay A/B/D is OFF

Press transmitter button D, the receiver relay D is ON, the relay A/B/C is OFF.

It also mean .Latched only can keep 1CH ON .and it will often have 1CH is ON.

When drive the MCU directly ,the I/O port cant connect the pull-up or pull-down resistors because the drive current of RXB12-X data output pin is weak.Also the inner pull-up or pull-down resistors of MCU should be disabled.
