user manual 1. Product Overview 1.1. Brief Introduction USR-DR404 supports serial port to WIFI function, make the serial port (RS485)connection switch into TCP/IP net interface to realize the bi-direction transparent transmission between serial port and WIFI/Ethernet. Enable serial devices to have TCP / IP network interface function immediately, connect to the network for data communication, greatly extend the communication distance of serial devices, as below: Basic function Standard certification Wireless standard Frequency range Wireless parameters Transmitting power User can configure...

Networking application USR-DR404 supports wireless WIFI and wired Ethernet communication modes, flexible networking and network topology. 2.1. Wireless Networking Configuration USR-DR404 can configure to be a STA or an AP. Can be set by AT command, web page, as below: (1) AT command...

user manual Diagram 2 Set WiFi mode in web page Click “Apply”, enter “Device Management”interface, restart. AP+STA function, can be set by AT command or customized as the factory default. 2.2. Wireless networking application 2.2.1. Wireless networking application(AP) WIFI can do as a AP, other serial port device and PC as a STA can connect the WIFI, also it can connected to user device via RS485, as fellows: The WIFI serial server works in AP mode. The above applications can be set using the following AT commands: (1) Set the WIFI server to AP mode AT+WMODE=AP Jinan USR IOT Technology Limited

user manual (2) The parameters of the WIFI serial server in AP mode can be set according to needs or use the default parameters. For example: AT+WAP=11BGN,USR-DR404-TEST,Auto(Optional) AT+WAKEY=WPA2PSK,AES,12345678(Optional) (3) Restart AT+Z Note: 1. All AT command settings need to enter the AT command mode (for details, please refer to the section “4.3.1. Serial AT Commands”) 2. After restarting the device, the parameter settings take effect. To refresh the original configuration information in memory and restart the operation. 2.2.2. STA Mode USR-DR404 do as STA and connect to other APs...

user manual 2.2.3. AP+STA USR-DR404 can support one AP and one STA meanwhile. Enable the AP+STA function, STA and AP interface can be used meanwhile, STA interface connected to the router, and then connected to the server in the internet via TCPB; AP interface can be connected by the phone/ pad (TCPA). So the TCP server, phone /pad can control the device connected to the DR404 and configure the parameters for the DR404. As below: WIFI serial server parameter settings are as follows: (1) Enable AP + STA function of WIFI serial server AT+FAPSTA=on (2) Parameters take effect after resetting...

user manual When the AP + STA function is enabled, the STA port needs to be connected to another router. Otherwise, the STA port will continuously scan the router, which will affect the AP port during scanning, such as data loss. If the user determines that the STA cannot connect to the AP at this time, you can use the command to stop the scanning of the STA port: AT+STTC=on/off “on” means to scan the router, “off” means not to scan, this command will not save after restart. AT+FSTTC=on/off This command can be saved, takes affect after restart. Web page settings: Login to built-in web...

user manual WIFI serial server parameter settings are as follows: The WIFI serial server numbered 1 works in STA mode, and the numbered 2 works in AP mode: (1) For No. 1 WIFI serial server, set to STA AT+WMODE=STA (2) For No. 2 WIFI serial server, set to AP AT+WMODE=AP (3) The WIFI serial server No. 1 is connected to the AP (WIFI serial server 2) as a STA. Therefore, the SSID and password to be connected to WIFI serial server 1 are the AP parameters of WIFI serial server 2. The SSID and password of the No. 2 WIFI serial server can be queried by the following AT command: AT+WAP AT+WAKEY Can...

Through this 100M Ethernet interface, users can realize the interconnection of the three interfaces of WIFI, serial port and Ethernet port. In terms of networking, the USR-DR404 serial server network port can be set to LAN port and WAN port; at the...

user manual AP+LAN Application WIFI serial server parameter settings: (1) Enable Ethernet interface AT+FEPHY=on (2) The above settings will take effect after restoring factory settings AT+RELD AT + RELD command does not restore the above settings. (3) Set USR-DR404 to AP AT+WMODE=AP (4) For the LAN parameters of the serial server, can use the default parameters or modify the IP address (DHCP gateway) and subnet mask of the serial server. Here are the default parameters: AT+LANN=10.10.100.254,255.255.255.0 (5) Restart 2.4.2. Wired Networking Applications (AP+ WAN) USR-DR404 works in AP mode,...
