Press again to clear the key, the data is cleared and exit charge cleared, cleared so far completed.C. Serial CommunicationThe module is equipped with a TTL serial data communication interface via the serial port can be read and set the relevant parameters; but if you want a device with a USB or RS232 (such as computers) to communicate, then you need to be equipped with different TTL adapter hardware board (USB communication needs with TTL to USB adapter plate; RS232 communication needs with TTL to RS232 adapter plate), the adapter plate of the specific connection details can be found in FIG.D. Description of the communications1. 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 supports communication port COM2 \ COM3 \ COM4, through the Device Manager to view, if not more than a few ports you need to modify the port over.E. Considerations1. This module is suitable for indoor, not outdoor use.2. the applied load should not exceed the rated power.3. The wiring can not be wrong.F. Specifications1.
