RS485 TO ETH Figure 4 Static IP/DHCP 2.1.2. RESTORE DEFAULT SETTI NGS Hardware: User can press Reload over 5 seconds and less than 15 seconds then release to restore default settings. Software: User can use setup software to restore default settings. -
Page 9: Socket Functions
RS485 TO ETH work in TCP Client mode need connect to TCP Server and need set the parameters: Remote Server Addr and Remote Port Number. RS485 TO ETH work in TCP Client won’t accept other connection request except target server and will access server with random local port if user set local port to zero. -
Page 10: Tcp Server
TCP Server mode also support Keep-Alive function. RS485 TO ETH work in TCP Server mode will listen local port which user set and build connection after receiving connection request. Serial data will be sent to all TCP Client devices connected to RS485 TO ETH in TCP Server mode simultaneously. -
Page 11: Udp Client
2.2.3. UDP CLIENT UDP transport protocol provides simple and unreliable communication services. No connection connected/disconnected. In UDP Client mode, RS485 TO ETH will only communicate with target IP/Port. If data not from target IP/Port, it won’t be received by RS485 TO ETH. -
Page 12: Udp Server
User can set RS485 TO ETH in UDP Client mode and related parameters by setup software or web server as follows: Figure 8 UDP Client 2.2.4. UDP SERVER In UDP Server mode, RS485 TO ETH will change target IP every time after receiving UDP data from a new IP/Port and will send data to latest communication IP/Port. -
Page 13: Httpd Client
In HTTPD Client mode, RS485 TO ETH can achieve data transmission between serial port device and HTTP server. User just need set RS485 TO ETH in HTTPD Client and set the HTTPD header, URL and some other related parameters, then can achieve data transmission between serial port device and... -
