Q1: How to configure transparent serial port application (TCP protocol) with
two DTU devices?
 Network structure as below figure:
 DTU 1# Setting:
 Works as AP mode; --See “Mode Selection Page”
 LAN IP address: 10.10.100.254; --See “AP Interface Setting Page”
 Network Protocal:TCP/Server, Port ID: 8899; -- See “Application Setting Page”
(DTU default setting);
 DTU 2# Setting:
 Works as STA mode; --See “Mode Selection Page”
 WAN connection type: DHCP or Static IP (For this example:10.10.100.100)
--See “STA Interface Setting Page”
 Network Protocal:TCP/Client, Port ID: 8899; Application IP address: Module 1#‟s LAN
IP address (10.10.100.254); -- See “Application Setting Page”
 Notes: When DTU 2# works as STA mode, DTU's WiFi interface works as WAN port.
DTU‟s WAN IP address and LAN IP address shall be setting different segment. So,
DTU 2#‟s LAN IP address must change to other segment; (For this sample, we change
to 10.10.99.254); --See “AP Interface Setting Page”
