Do
nothing
[Del 1] or [Del 2]: The data
will be transmitted when an additional byte (for
Del1), or an additional 2 bytes (for
Del2) 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
Local TCP port 1 to 65535 4001
The TCP port that the NPort uses to listen to
connections, and that other devices must use to
contact NPort. To avoid conflicts with well-
known TCP ports, the default is set to 4001.
Required
Command port 1 to 65535 966
The command port is a listen TCP port for IP-
Serial Lib commands from the host. In order to
prevent a TCP port conflict with other
applications, the user can adjust the command
port to another port if needed.
Optional
ATTENTION
The Inactivity time should at least be set larger than that of Force transmit timeout. To prevent the
unintended loss of data due to the session being disconnected, it is highly recommended that this value is
set large enough so that the intended data transfer is completed.
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 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.
