NPort 5100A Series Web Console Configuration
Allow driver control
Setting Factory Default Necessity
No or Yes No Optional
If “max connection” is greater than 1, the NPort will ignore driver control commands from all connected hosts.
However, if you set “Allow driver control” to YES, control commands will be accepted. Note that since the NPort
5100A may get configuration changes from multiple hosts, the most recent command received will take
precedence.
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.
ATTENTION
Delimiter 2 is optional. If left blank, then Delimiter 1 alone trips clearing of the buffer.
If the size of the serial
data received is greater than 1 KB, the NPort 5100A
will automatically pack the data and send it to the
However, to use the delimiter function, you must at least enable Delimiter 1. If Delimiter 1 is left
blank and Delimiter 2 is enabled, the delimiter function will not work properly.
Delimiter process
Setting Factory Default Necessity
Do Nothing,
Delimiter + 1,
Delimiter + 2,
Strip Delimiter
Do Nothing Optional
[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 are 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.
Force transmit
Setting Factory Default Necessity
0 to 65535 ms 0 ms Optional
0: Disable the force transmit timeout.
1 to 65535: Forces the NPort 5100A’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 5100A fetches the serial data from its internal
buffer. If data is incoming through the serial port, the NPort 5100A stores the data in the internal buffer. The
