[Introduction]：The NS8-V2 Ethernet module is a surface-mount Ethernet serial server module that converts data from eight serial ports to Ethernet. Featuring multiple Modbus gateway modes and TCP/DUP/MQTT/HTTP IoT gateway modes, the Ethernet module can connect various serial devices and PLCs. The serial-to-Ethernet module utilizes an LCC package, making it easy to integrate onto PCBs.
