The device has two buffer areas, which are the serial data buffer and the network data buffer. When the SOCKET clear cache

function is enabled, only the cache data of the relevant SOCKET link will be cleared, and the serial cache data will not be cleared.

3.5.9 Link/ data transmission indication

Link indicates the status of the network connection. In TCP mode, when the network is not connected, the Link is off, and when

the connection is established, the Link is always on. The Link indicator is always on in UDP mode.

The other one is the data transmission indication, showing the transmission status of the DTU. When there is no data transmission

on the DTU, the data transmission indicator is off. When there is data transmission on the DTU, the flashing indicates that the period is
60ms and the indicator is on for 10ms.

3.5.10 Restore to factory setting

The DTU is restored to the factory settings either by software or by button.
