WORKING MECHNISM

DZM5168MM communicates with the host through five pins. The UART data format of

DZM5168MM must be the same as the host. User can reset the module through AT command or

I/O port. Please note that the external reset circuit should be consisted of a 18K resistor and a

470nF capacitor (seeing the connection diagram below). DZM5168MM module works in two

different modes: Transparent mode and API mode which can be switched between them freely by

AT command.
