NPort 5200 Series User’s Manual
Web Console Configuration
5-23
If the user wants to send a series of characters in the same packet, the serial device attached to
NPort 5200 should send that series of characters during a time interval less than the Force transmit
timeout for NPort 5200, and the total length of data must be less than or equal to NPort 5200’s
internal buffer size. The serial communication buffer size for NPort 5200 is 1 KB per port.

The UDP port that NPort 5200 listens to, and that other devices must use to contact NPort 5200. To
avoid conflicts with common UDP ports, the default is set to 4001.
Pair Connection Mode
Pair Connection Mode employs two NPort 5200 device servers in tandem, and can be used to
remove the 15-meter distance limitation imposed by the RS-232 interface. One NPort 5200 is
connected from its RS-232 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 port of the
other NPort 5200. The two NPort 5200 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 5200 device servers. In effect, this NPort 5200 will be acting
as a TCP client.
