Function Declaration


FUNCTION DESCRIPTION

   

    Product functions can be divided into: default mode, serial port to Ethernet, serial port to WiFi CLIENT and serial port to WiFi AP。


   


·In this mode, WiFi and LAN functions are turned off, and COM1 data and WAN network data are converted to each other through setting。

·Ethernet can be configured as dynamic IP address (DHCP) or STATIC IP address (STATIC)。


   


·In this mode, WAN and LAN functions are turned off, and COM1 data and WiFi data are converted to each other through setting。

·WiFi CLIENT can be configured as dynamic IP address (DHCP) or STATIC IP address (STATIC)。

·WiFi security supports all current encryption methods。


   



·In this mode (AP mode), WAN and LAN functions are turned off, and COM1 data and WiFi data are converted to each other through setting。

·WiFi devices can connect to the product and become devices under WiFi LOCAL area network。

·WiFi security supports all current encryption methods。


   



·In this mode (AP mode), WAN and LAN functions are available. COM1 data and WiFi data can be converted to each other through setting。

·WiFi devices can connect to the product and become devices under WiFi LOCAL area network. WAN - end default dynamic IP address mode. LAN and WiFi are the same LAN, and DHCP server is on by default

·WiFi security supports all current encryption methods。



The serial port/network data transformation of the product can be divided into four modes: TCP Server, TCP Clinet, UDP Server and UDP Client。



TCP Server


   



·In this mode, the module listens to the specified port and waits for TCP Client to connect. After connecting, all TCP data is directly sent to the serial port, and the serial port data is sent to all TCP Client terminals



TCP Client


   


·In this mode, the module connects to the specified domain name /IP and port. All data sent from the TCP Server side is directly sent to the serial port side, and the serial port side is sent to the TCP Server side

·A network exception can cause active reconnection of the product. When TCP active reconnect is available, TCP Server will disconnect and the product will reconnect immediately; otherwise, the module will not reconnect



UDP Server


   


·In this mode, the module opens the local designated port. Once the data sent to this port is received, the module will send the data to the serial port and record the IP and port of the remote terminal. The module records only the remote information on the last connection. The data received by the serial port will be sent directly to the recorded remote IP and port。



UDP Client


   


·In this mode, the module directly sends serial port data to the specified IP and port. The data returned from the server will be sent to the serial port。
