RS232/485 TO WIFI POE ETH (B) User Manual
The RS232/485 TO WIFI POE ETH (B) serial server is used as AP, Ethernet port is set as WAN port,
and it is connected to the route that can access the external network, so the DHCP server function is
enabled. The serial server is used as a secondary router, and a PC or other smart handheld device can
access the Internet by connecting to the serial server AP. At this time, the default AP of the serial port
server is usually RS232/485 TO WIFI POE ETH (B)_xxxx, which has no encryption and can be set
through web pages or at commands.
After the serial server is connected to the AP, it obtains the IP address from the AP (as shown in
Figure 192.168.1.10). The serial server itself forms a subnet (default is 10.10.100.254), and the
devices on the Ethernet port are assigned addresses by the serial server (as shown in Figure
10.10.100.100, as shown below):
Serial server parameter setting:
(1) Enable Ethernet port
AT+FEPHY=on
(2) Set the serial server Ethernet port to work in WAN port mode
AT+FVEW=enable
(3) Restore factory settings for the above settings to take effect
AT+RELD
Note: The AT+RELD command will not restore the above settings.
(4) The serial server is operating in AP mode and DHCP is enabled (default, select settings)
AT+WMODE=ap
AT+DHCPDEN=on
(5) Considering security, you can modify the AP name and encryption parameters (optional).
AT+WAP=11BGN,B2-WIFI-TEST,Auto (select setting)
AT+WAKEY=WPA2PSK,AES,waveshare (select setting)
(5) You can choose to set the LAN parameters of the serial server, including IP address (DHCP
gateway) and subnet mask (optional).
