Three. Button

A built-in button on the panel, used to make electricity clear function.
Electricity clear method: Press ZERO key five seconds, then release the button. Press again to clear the key, the data is cleared and exit charge cleared, cleared so far completed.

Serial Communication

The module is equipped with a TTL serial data communication interface. Via the serial port, you can read and set the relevant parameters. If you want a device with USB or RS232 (such as computers) to communicate, then you need to use a TTL adapter hardware board (USB requires TTL-to-USB adapter; RS232 requires TTL-to-RS232 adapter).

Description of the communications

Connect the hardware according to the wiring diagram.
After connecting, select the communication port in PC software (COM2 / COM3 / COM4). Use Device Manager to check available ports and modify if needed.

Function
