NPort 5100 Series Web Console Configuration

5-20

Therefore, you should set Force transmit timeout to be larger than 8.3 ms, so in this case, it must be greater

than or equal to 10 ms.

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.
