DTX1K wireless remote control transmitter module 433MHz with coded EV1527 (แถมเสาแบบขดลวด)

 

From left to right ANT, GND, LED, SW, VT, D0, D1, D2, D3, VDD, GND

(10) the output mode: the choice of point moving, self locking and interlocking;

 

1. default (T2, T1 suspension) is a point moving mode with a valid signal input, the corresponding output signal has output, and the effective signal does not stop automatically after the output.

2. panel (T2 grounding and T1 suspension) is self locking mode, with effective signal input, corresponding output signal state inversion, before output high level becomes low level, vice versa.

3. board (T2 suspension, T1 grounding) is interlocking mode, with effective signal input, the corresponding output signal has output, and the other is closed. The signal is indicated; when the effective signal is input, the VT output is high, and the VT is the output low after the effective signal is disappearing.

 

The code method:

 

Short press the learning key for 2 seconds, learn the indicator light to light up, at this time, it indicates that it has entered the learning state, unlearn the learning key, and press any button on the remote control to indicate 4 times of flickering, indicating that learning is successful and quit learning mode.

 

Clearing code method:

 

Continue to hold down the learning key, indicating that the lamp is often bright, hold down for about 8 seconds after the light is extinguished, indicating that the code has been completely cleared.

 

Application scope:

 

(1) automobile remote control door switch (RKE); (2) remote control door opener; (3) wireless security alarm; (4) remote control curtain machine; (5) wireless industrial controller; (6) wireless data transmission.
