NPort 5100 Series User’s Manual
Web Console Configuration
5-22
If the user wants to send a series of characters in the same packet, the serial device attached to
NPort 5100 should send that series of characters during a time interval less than the Force transmit
timeout for NPort 5100, and the total length of data must be less than or equal to NPort 5100’s
internal buffer size. The serial communication buffer size for NPort 5100 is 1 KB per port.

The UDP port that NPort 5100 listens to, and that other devices must use to contact NPort 5100.
To avoid conflicts with well known UDP ports, the default is set to 4001.
Pair Connection Mode
Pair Connection Mode employs two NPort 5100 device servers 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 device servers 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.
Pair Connection Master Mode
When using Pair Connection Mode, you must select
Pair Connection Master Mode
for the
Operation mode of one of the NPort 5100 device servers. In effect, this NPort 5100 will be acting
as a TCP client.
