RS232/485 TO WIFI POE ETH (B) User Manual
<Note>:
Network parameters can be set in four modes: TCP Server, TCP Client, UDP Server, and UDP
Client.
When the RS232/485 TO WIFI POE ETH (B) serial server is configured as a UDPServer, the
RS232/485 TO WIFI POE ETH (B) serial server will remember the UDPClient end of the last
communication and communicate with the last UDPClient end. The UDPClient mode only
communicates with the target IP and port. When set to TCP Server, there is no need to enter an IP
address. For other settings, it is necessary to fill in the IP address of the other party that needs to be
connected. Fill in the protocol port number at the port, and the port numbers on both ends of the
communication must be the same.
SocketB communicates with the server as the TCPClient and UDPClient.
TCP connection password verification: When RS232/485 TO WIFI POE ETH (B) is working in TCP
Server mode, perform password verification on the connected TCPClient.
Note: This verification only works when the RS232/485 TO WIFI POE ETH (B) serial server is used
as the TCP Server. When enabled, TCPClient connects to the TCPServer of the WIFI serial port server,
the first data sent to RS232/485 TO WIFI POE ETH (B) serial server is password plus carriage return.
The password is the password when logging in to the webpage, and the default is "admin". For
example, the first data sent by default should be "0x610x640x6d 0x690x6e0x00d 0x0a"
(hexadecimal).
