Three! Button

1. A button built into the panel, used to make electricity work clearly, as shown in Figure 2.
2. Electricity cleaning method: Press the zero key for five seconds and release the button. Press again to delete the key, the data is deleted and the output load is deleted, it has been completed so far.

C serial communication

The module is equipped with a serial TTL, data communication interface through the serial port can be read and set the relevant parameters; but if you want a device with a USB or RS232 cable (such as computers) to communicate, you need to be equipped with different TTL adapter hardware boards (USB communication needs with TTL to USB adapter plate; RS232 communication needs with TTL to RS232 adapter plate) adapter plate specific connection details can be found in fig.

D. Description of communications

1. Connect the hardware according to the wiring diagram.
2. Connect the line after a good First select the communication port of the PC software module communication port COM2, COM3 ,COM4 through the device manager view if there are no more than a few ports, you have to modify the port.

E considerations

1. This module is suitable for indoor use, not outdoors.
2. The applied load must not exceed the rated power.
3. The wiring can not be wrong.
