successful, the device will automatically disconnect if no data is received from the serial port or no data is sent or
received from the network port within the set time.
The short link hold time is set to 0 to turn off the short connection function. When the setting range is (2-255)
seconds, the short connection function is turned on, and the default hold time is 0 seconds (short link is turned off).
5.4 Disconnect and reconnect
In client mode, the device tries to actively connect to the server at the specified time after the network is
disconnected. If the request times out and reaches the set number of reconnections and is not successfully
reconnected, the device will perform a reboot to prevent the network from being reconnected after the device is
disconnected.
Disconnection reconnection time: the time interval between each attempt of the device to re-establish the
network.
Reconnect times: The number of times the device tries to re-establish the network. If the cumulative number
of requests reaches the preset value, the device will automatically reboot if the connection is not yet successful.
The actual reboot time is the disconnection period multiplied by the number of reconnection times, and it is
recommended to use the factory default parameters without special requirements.
5.5 Timeout restart
Support timeout restart function (default: 300 seconds), this function is mainly used to ensure the long-term
stable operation of the device. If no data is sent or received within the set timeout restart time, the device will be
restarted to avoid the abnormal situation to affect the communication.
Timeout restart time parameter range (60-65535) seconds, configured as 0 means turn off timeout restart. The
default is 300 seconds.
5.6 Cache cleaning
The device is in client mode, when the TCP connection is not established, the data received by the serial port
will be put in the cache area, the serial port receive cache is 1024 bytes, greater than 1024 bytes will overwrite the
earliest received data, after the network connection is successful, you can choose to clear the serial port cache or
send the cache through the network by configuration.
Enable: The device does not save the data received by the serial port before the connection is established.
Disable: The network will receive the data cached on the serial port after the connection is established.
5.7 Remote configuration
The remote configuration function of the upper computer and web page can be used to configure the remote
digital radio. This series of products (E90-DTU(xxxSLxx-ETH)_V2.0) does not support being remotely configured,
and remote configuration requires the remote device and the configuration device to communicate normally,
otherwise the configuration command cannot reach the remote device.
After sending the remote configuration command, the indicator DATA double blinks and receives the remote
