Ethernet Switch Controller Module Network Review

This 8-way 10A relay controller has normally open and normally closed output. 8-way switch on-off input. Can be used for smart home control, secondary development of mobile phone or computer remote control lights, motors, and other electrical equipment. Can be used for computer room power failure detection, can be connected to human body infrared sensor, button switch and smoke alarm output. C++ source code is provided. Reliable network connection, network will automatically reconnect if it is off-line. In TCP service mode, it can support 4 network connection, using 32-bit MCU. Very convenient network parameter setting software. Support working in TCP server, TCP client, and UDP mode. Support 4 client connection when working in TCP server mode. Supports user-defined name, no need to record IP number when there are many equipment. Supports user-defined heartbeats packet time, reliable off-line network restore. Can work in switch on-off unvarnished transmission mode. Download three firmware through configuration project, respectively are general firmware, switch on-off unvarnished transmission firmware, access control firmware. General firmware is working in slave mode, using command to control. Switch on-off unvarnished transmission firmware is used in pairs, one input control the other output, each input correspondingly controls other relay output. Access control firmware can connect to four 26 protocol read heads
