NPort 5100A Series Web Console Configuration
RFC 2217 Mode
TCP alive check time
Setting Factory Default Necessity
0 to 99 min 7 min Optional
0 min: TCP connection is not closed due to an idle TCP connection.
1 to 99 min: The NPort 5100A automatically closes the TCP connection if there is no TCP activity for the given
time. After the connection is closed, the NPort 5100A starts listening for another host’s TCP connection.
Local TCP port
Setting Factory Default Necessity
1 to 65535 4001 Required
The “Local TCP port” is the TCP port that the NPort 5100A uses to listen to connections, and that other devices
must use to contact the NPort 5100A. To avoid conflicts with well known TCP ports, the default is set to 4001.
Packing length
Setting Factory Default Necessity
0 to 1024 0 Optional
Default = 0: The Delimiter Process will be followed, regardless of the length of the data packet. If the data
length (in bytes) matches the configured value, the data will be forced out. The data length can be configured
for 0 to 1024 bytes. Set to 0 if you do not need to limit the length.
Delimiter 1
Setting Factory Default Necessity
00 to FF None Optional
Delimiter 2
Setting Factory Default Necessity
00 to FF None Optional
Once the NPort 5100A receives both delimiters through its serial port, it immediately packs all data currently
in its buffer and sends it out the NPort 5100A’s Ethernet port.
Delimiter process
Setting Factory Default Necessity
Do Nothing,
Delimiter + 1,
Delimiter + 2,
Strip Delimiter
Do Nothing Optional
