USR-DR404 1-Port RS485 to 802.11 a/b/g/n WLAN Serial Device Server

Package: USR-DR404 *1 PCS Antenna* 1 PCS Power Supply *1 PCS USR-DR404 supports serial port to WIFI function, make the serial port (RS485)connection switch intoTCP/IPnetinterface to realize the bi-direction transparent transmission between serial port and WIFI/Ethernet. Enableserial devicesto have TCP / IP network interface function immediately, connect to the network for data communication, greatlyextendthe communication distance of serial devices Features：  Support 802.11b/g/n wireless standards.  Support usr-link.  Support route and bridge modes.  Support RS485 to Wifi/ Ethernet communication.  Rich indicator LED: Power, link, RXD, TXD.  Wide voltage DC 5~36V, support terminal power.  Support transparent transmission mode, serial command mode, HTTPD Client (GET, PUT and POST), MODBUS,ATcommand mode.  Support three types of registration packets: MAC, USR-Cloud, custom.  Support custom heartbeat packet, distributing socket protocol, MODBUS polling function  Support timeout reset function, timing reset function.  Support remote upgrade.  Add hardware watch dog, makes more stable  Supports free framing and automatic framing on the serial port, for higher forwarding efficiency.  Support websocket and realize the timing communication for serial port and web page.  Support web page, serial/network AT command to configure parameters.  Support one key (press the reload button for more than 5 seconds) to restore factory settings.  Long distance communication: two serial server can transport for 150m(Test conditions: open line of sight, twoWIFIserial servers self-networking, 57600 baud rate, no packet loss during transmission).  Designed with guide rails for easy installation.
