[Introduction]:NA111-E is a serial port server that realizes serial port data ⇌ Ethernet data conversion; it has multiple Modbus gateway modes and MQTTC/HTTPC IoT gateway modes, which can meet the networking functions of various serial port devices/PLCs; it adopts industrial-grade design standards to ensure equipment reliability; the product can be installed using guide rails or positioning holes. The product is sprayed with three-proof paint, which has functions such as "anti-mold", "anti-humidity" and "anti-salt spray".
