1597
1598 LHT65N supports AT Command set.User can use a USB to TTL adapter plus the Program Cable to
1599
1600 connect to LHT65 for using AT command, as below.
1601

1612
1613 ✓ USB to TTL 3.3V <~-~-> D-
1614
1615 In PC, User needs to set serial tool(such as **putty**, SecureCRT) baud rate to **9600** to access to
1616
1617 access serial console for LHT65N. The AT commands are disable by default and need to enter
1618
1619 password (default:**123456**) to active it. Timeout to input AT Command is 5 min, after 5-minute,
1620
1621 user need to input password again. User can use AT+DISAT command to disable AT command
1622
1623 before timeout.
1624
1625 Input password and ATZ to activate LHT65N,As shown below:
