Little common sense (very important):
Data download: Http://pan.baidu.com/s/1dd7zazv
Txd: Transmitting terminal, generally expressed as its own transmitting terminal, normal communication must be connected to the rxd of another device.
Rxd: Receiving end, generally expressed as its own receiving end, normal communication must be connected to the txd of another device.
During normal communication, the txd of the device is always connected to the rxd of the device!
Self-receiving and self-transmitting: Rxd is connected to the txd of other devices during normal communication, so if you want to receive the data sent by yourself, as the name suggests, that is, you receive the data sent by yourself, that is, your own txd is directly connected to rxd to test its own transmission and reception whether it is normal or not is a quick and simple test method. When a problem occurs, the first test is performed to determine whether the product is faulty. Also called loopback test.
Level logic:
Ttl level: Usually data is expressed in binary, and it is stipulated that +5v is equivalent to logic ‘1’, and 0v is equivalent to logic ‘0’, which is called ttl signal system, which is positive logic
Rs232 level: Use -12v to -3v, which is equivalent to logic ‘0’, +3v to +12v logic level, which is equivalent to logic ‘1’, which is negative logic
Product manual:
