4.4.3 Registration package function

In the client mode, the user can choose to send the registration package, and set the registration package time
by definition.
The registration package supports the following modes:
(1) The MAC address (OLMAC) is sent when the network establishes a connection with the device
(2) The data of the custom registration package sent when the network establishes a connection with the
device (OLCSTM)
(3) After the network and the device are connected, each packet of data sent by the device to the network is
preceded by a MAC address (EMBMAC)
(4) After the network and the device are connected, each packet of data sent by the device to the network is
prepended with custom registration packet data (EMBCSTM)
Custom registration package content (maximum support 40 bytes (ASCII) data, 20 bytes (HEX) data)

4.4.4 Short connection function

In client mode, short network connection is supported (this function is disabled by default). TCP short

When the short link hold time is set to 0, the short link function is turned off. When the setting range is (2-255)
seconds, the short connection function is enabled, and the default hold time is 0 seconds (disabled).

4.4.5 Timeout restart function

Supports the timeout restart function (default: 300 seconds), which is mainly used to ensure the long-term
stable operation of the device. If data is not sent and received within the set timeout restart time, the device will
restart to avoid the impact of abnormal conditions on communication.
The parameter range of timeout restart time is (60-65535) seconds. If it is set to 0, it means shutdown timeout
restart. The default is 300 seconds.
