NP302 series can conveniently connect up to 2 serial devices to an Ethernet, allowing you to network your existing serial devices with only basic configuration. With NP302 series, you can both centralize the management of your serial devices, and distribute management hosts over the network.
NP302 series can be used to connect different devices for remote management, each serial port operates independently to provide maximum versatility, each port can be operate in Driver, TCP Server, and TCP Client mode independently.
