Support TCP, UDP, ARP, ICMP, HTTP, TELNET and DHCP protocol 6. Support across gateway, router communication 7. Support standard TCP/IP SOCKET 8. Support Virtual serial driver access and auto connect after the network disconnect 9. Choice of configuration methods: Windows, TELNET and WEB Introduction NP304 series 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 series, you can both centralize the management of your serial devices, and distribute management hosts over the network. NP304 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.
