NPort IA5150/5250 Series User’s Manual Web Console Configuration
5-20
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 (hex) None Optional
Delimiter 2
Setting Factory Default Necessity
00 to FF (hex) None Optional
Once the NPort IA5150/5250 receives both delimiters through its serial port, it immediately packs
all data currently in its buffer and sends it to the NPort IA5150/5250’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 IA5150/5250 will automatically pack
the data and send it to the Ethernet. 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 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.
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 IA5150/5250’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 NPort IA5150/5250 fetches the serial data
from its internal buffer. If data is incoming through the serial port, NPort IA5150/5250 stores the
data in the internal buffer. NPort IA5150/5250 transmits data stored in the buffer via TCP/IP, but
