NPort 5100 Series Choosing the Proper Operation Mode

4-4

UDP Mode

Compared to TCP communication, UDP is faster and more

efficient. In UDP mode, you can unicast or multicast data

from the serial device to one or multiple host computers, and

the serial device can also receive data from

one or

multiple

host computers, making this mode ideal for message display

applications.

Pair Connection Mode

Pair Connection Mode employs two NPort 5100 in tandem, and can be used to remove the 15-meter distance

limitation imposed by the RS-232/422/485 interface. One NPort 5100 is connected from its RS-232/422/485

port to the COM port of a PC or other type of computer, such as hand-held PDAs that have a serial port, and the

serial device is connected to the RS-232/422/485 port of the other NPort 5100. The two NPort 5100 are then

connected to each other with a cross-over Ethernet cable, both are connected to the same LAN, or in a more

advanced setup, they communicate with each other over a WAN (i.e., through one or more routers). Pair

Connection Mode transparently transfers both data and modem control signals (although it cannot transmit the

DCD signal) between the two NPorts.

Ethernet Modem Mode

Ethernet Modem Mode is designed for use with legacy operating systems, such as MS-DOS, that do not support

TCP/IP Ethernet. By connecting one of NPort 5100’s serial ports to the MS-DOS computer’s serial port, it is

possible to use legacy software originally designed to transmit data via modem, but now transmit the data over

the Ethernet.
