Product Descriptions
NS 4 is serial to Ethernet server module that realizes serial data and Ethernet data conversion.it provides 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.
The NS 8 -TB test kit comes with a USB-to-TTL circuit that does not require the user to connect an external converter, and leads to reset and factory reset pins for external buttons for easy operation, and also connects the operating status indicator pins to external LEDs for users to observe the status .
