1588
1589 LHT65N supports AT Command set.User can use a USB to TTL adapter plus the Program Cable to
1590
1591 connect to LHT65 for using AT command, as below.

1606 In PC, User needs to set serial tool(such as **putty**, SecureCRT) baud rate to **9600** to access to
1607
1608 access serial console for LHT65N. The AT commands are disable by default and need to enter
1609
1610 password (default:**123456**) to active it. Timeout to input AT Command is 5 min, after 5-minute,
1611
1612 user need to input password again. User can use AT+DISAT command to disable AT command
1613
1614 before timeout.
1615
1616 Input password and ATZ to activate LHT65N,As shown below:
