NPort servers from Moxa allow connection of devices with a serial interface (RS232/422/485) in TCP/IP networks, for transmission of serial data over a local network or via the Internet with no restriction on the distance. Serial devices such as measuring instruments, barcode readers, label printers, and so on, can thus be centrally controlled and evaluated from any location. Thanks to the various operating modes, NPort servers can be used for virtually all serial applications:
Real COM Mode: In order to enable a computer to access the interfaces of the NPort server, virtual COM/TTY ports are created with the aid of driver software under Windows/Linux. In this way the existing applications can be used for serial communications.
Pair Connection Mode: With the aid of two Nport servers (5110/DE-211/DE-311), two serial devices can be connected directly to each other via a local Ethernet or via the Internet.
Ethernet Modem Mode: With this operating mode, computers with non TCP/IP-capable operating systems (e.g. MS-DOS) are also able to access Nport servers via networks/Internet. To do this, an additional Nport server is connected to the serial interface of the computer, and this is then integrated in the network at the Ethernet port. The serial connection is set up via a modem
