2. Send custom registration package data (OLCSTM) when establishing a connection between

3. After establishing a connection between the network and the device, each packet of data

sent by the device to the network is prefixed with a MAC address (EMBMAC).

4. After establishing a connection between the network and the device, each packet of data

sent by the device to the network is preceded by a custom registration packet data

(EMBCSTM).

Custom registration package content (supports up to 40 bytes of ASCII data and 20 bytes of

HEX data)

[Note] It is recommended not to use special characters (such as "," "/", "/", etc.) when

configuring the registration package. If you want to use it, it is recommended to use hexadecimal

configuration.

5.2 Short connection

In client mode, network short connections are supported (disabled by default), while TCP short

connections are mainly used to save server resource costs and are generally applied in multi-point

(multi client) to one point (server) scenarios.

The TCP short connection function is applied in the TCP Client mode. After enabling the short

connection function, only a request is made to connect to the server when sending information. After

the connection is successful, if the serial port does not receive or receive data or the network port

does not receive or receive data within the set time, the device will automatically disconnect.

Turn off the short link function when the short link retention time is set to 0. When the setting

range is (2-255) seconds, the short connection function is turned on, and the default hold time is 0

seconds (close short links).

When the TCP connection is not established, the data received by the serial port will be placed

in the cache area. The serial port receive cache is 512 bytes. After the network connection is

successful, you can choose to clear the serial port cache or send the cache through the network

through configuration.
