Encoding Type: Learning Button to add Transmitter
Working Mode: Momentary Toggle Latched adjustable
Pin No. Pin Name Instruction
1 VT Output Status Indication
2 D Data Output
3 C Data Output
4 B Data Output
5 A Data Output
6 5V Power+
7 GND 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.
Notes
When drive the MCU directly ,the I/O port cant connect the pull-up or pull-down resistors because the drive current of RXB12s data output pin is weak.Also the inner pull-up or pull-down resistors of MCU should be disabled.
