Usr-Tcp232-410S is a Dual Serial Server, Which Supports RS232 and RS485 Working at The Same Time. it is Based On Cortex-M4 Solution and The Internal of The Serial Server Integrates Tcp / IP Protocol Stack. Besides, Usr-Tcp232-410S Has The Function of Terminal Power Supply. Feature Multiple Indicator Lights for Convenient Debugging Power-Line Terminal for Industrial Application Arm Kernel and Tcp / Ip Protocol Stack Auto-Mdi / Mdix, Rj45 Port with 10 / 100Mbps Tcp Server, Tcp Client, Udp, Udp Server and Httpd Client Work Mode Two Ports Can Work Independently at The Same Time Support Virtual Serial Port and Provide Corresponding Software Usr-Vcom Serial Baud Rate From 600Bps to 230. 4K Bps; Check Bit of None, Odd, Even, Mark and Space Dns and Dhcp Supported Provide Pc Tcp / Ip Socket Programming Example, Vb, C++, Delphi, Android, Ios Built-In Webpage; Also Can Customize Webpage for Users Reload Button, One Key to Restore Default Settings Rj45 with Link / Data Indicator Light, Built-In Isolation Transformer and 2 Kv Electromagnetic Isolation The Global Unique Mac Address Bought From Ieee, User Can Define Mac Address Supp Ort Upgrade Firmware Via Network Support Keep-alive, Rapidly Detect Dead Links Support Account and Password, Can Be Used to Page Login and Network Settings Support One Channel Websocket, Realize Bidirectional Transparent Transmisison Bewteen Webpage and Serial 0 Support Modbus Rtu to Modbus Tcp Support Udp Broadcast Function, Send and Receive Data From All Ip in The Network What is in The Box: 1 x Dual Serial Device Server, 1 x 5V 1a Power Supply, 1 x Female to Female Serial Cable. Review: Worked 1st time out of the box. - Bought this to connect my Solar Inverter to my Home Assistant set up. Worked perfectly out of the box. Impressed. Review: Just what was required - Purchased to allow my local Home Assistant installation to communicate with my Fox ESS inverter. Easy installation using a GitHub guide and working no issues - went with this one over wireless options as I prefer wiring devices wherever possible (leaving WiFi for devices that can only connect via WiFi). ## Features - Dual Serial Device Server: Cpu: Cortex-M4 120Mhz, Serial RS485 & RS232 to Ethernet Server, 2 Serial Ports: 1 Port is RS232, 1 Port is RS485, 1 RJ45 Ethernet Port.
