4.7.3AT command configuration
Query and modify the relevant parameters of the device can be completed through AT command
configuration. For specific AT commands, please refer to "AT Command Set".
4.7.4Configuration tool software settings
Open the configuration tool software, search for the device, double-click the recognized device,
and the parameter query configuration interface will pop up. You can customize relevant parameters
according to your needs, then save the configuration, restart the device, and complete the parameter
modification.
【Note】:
Do not use multiple configuration tools in the same LAN environment. Industrial computers
with multiple network cards need to be temporarily disabled and do not use network cards, otherwise
the configuration tool will experience abnormalities (the same device is displayed multiple times, the
device cannot be found, etc.)
The configuration tool blocks the wireless network card, so the network cable must be
connected to use the configuration tool. The wireless network card can be configured through the
web page.
4.7.5Random local port
T CP client, U DP client, HTTP client, M QTT client can configure the local port to 0 (use a
random local port). Random ports cannot be used in server mode, otherwise the client cannot
establish a connection correctly.
Using a random port connection can quickly re-establish the connection when the device
accidentally disconnects from the server, preventing the server from rejecting the connection due to
four incomplete waves. It is recommended to use a random port in client mode.
The device will automatically enable random ports when configuring HTTP client and M QTT
client modes.
4.7.6Remote upgrade
In order to facilitate later maintenance and upgrade functions and replace different firmware, the
serial port server supports online upgrade. Through the upgraded firmware provided by our company,
users can upgrade or replace the current firmware through the configuration tool.
