NS2 Serial port to Ethernet module erial data ⇌ Ethernet data conversion
[Introduction]：NS2 is an Ethernet serial server module that realizes serial data ⇌ Ethernet data conversion; it has a variety of Modbus gateway modes and TCP/DUP/MQTT/HTTP IoT gateway modes, which can meet the networking functions of various serial devices/PLCs. The module adopts LCC package, which is convenient for user equipment to be integrated on the PCB board.
