NPort 5000 Series User Manual
Parameter Setting
Default
Description Necessity
Ignore
jammed IP
No or Yes No
No: When Max connections > 1, and the serial
device is transmitting data, if any one of the
connected hosts is not responding, it will wait
until the data has been transmitted successfully
before transmitting the second group of data to
all hosts.
Yes: If you select Yes for “Ignore jammed IP,”
the host that is not responding will be ignored,
but the data will still be transmitted to the other
hosts.
Optional
Packing length 0 to 1024 0
0: The Delimiter Process will be followed,
regardless of the length of the data packet.
Greater than 0: If the data length (in bytes)
matches the configured value, the data will be
Optional
Delimiter 1 00 to FF None
Once the NPort receives both delimiters through
its serial port, it immediately packs all data
currently in its buffer and sends it to the NPort’s
Ethernet port.

[Delimiter + 1] or [Delimiter + 2]: The data
will be transmitted when an additional byte (for
Delimiter +1), or an additional 2 bytes (for
Delimiter +2) of data is received after receiving
the Delimiter.
[Strip Delimiter]: When the Delimiter is
received, the Delimiter is deleted (i.e.,
stripped), and the remaining data is
transmitted.
[Do nothing]: The data will be transmitted
when the Delimiter is received.
Optional
Force Transmit 0 to 65535 ms 0 ms
0: Disable the force transmit timeout.
1 to 65535: Forces the NPort’s TCP/IP protocol
software to try to pack serial data received
during the specified time into the same data
frame.
This parameter defines the time interval during
which the NPort fetches the serial data from its
internal buffer. If data is incoming through the
serial port, the NPort stores the data in the
internal buffer. The NPort transmits data stored
in the buffer via TCP/IP, but only if the internal
buffer is full or if the force transmit time interval
reaches the time specified under Force Transmit
timeout.
Optional
ATTENTION
When Max connection is set to two or more, the NPort will use a “multiconnection application” (i.e., two or
more hosts are allowed access to the port at the same time). When using a multiconnection application,
the NPort will use the serial communication parameters set in the console. All of the hosts connected to
that port must use the same serial settings. If one of the hosts opens the COM port with parameters that
are different from the NPort’s console setting, data communication may not work properly.
