Introduction  

NP304 Serial Device Server can conveniently connect up to 4 serial devices to an Ethernet, allowing you to network your existing serial devices with only basic configuration. With NP304 Serial Device Server , you can both centralize the management of your serial devices, and distribute management hosts over the network.

NP304 Serial Device Server  can be used to connect different devices for remote management, each serial port of NP304 Serial Device Server operates independently to provide maximum versatility, and each port of NP304 Serial Device Server can be operate in Driver, TCP Server, and TCP Client mode independently.
