ATTENTION
The Inactivity time should be longer than the Force transmit timeout. To prevent the unintended
loss of data due a session getting disconnected, it is strongly recommended that this value is set
large enough so that the intended data transfer is completed.
ATTENTION
Inactivity time is only active when TCP connect on is set to Any Character.
Delimiter 1
Setting Factory Default Necessity
00 to FF “0” for None Optional
Delimiter 2
Setting Factory Default Necessity
00 to FF “0” for None Optional
The Delimiter fields are used to specify a character or 2-character sequence which will act as a
marker to control packing of serial data. By default, no delimiter characters are defined, so the
module transmits data as soon as it is received. When a delimiter character or characters are
defined, the module will hold data in its buffer until it receives the delimiter character or
2-character sequence. When the delimiter is received, the module will pack up the data in its buffer
and send it through the Ethernet port.
Use Delimiter 1 to define the first delimiter character in hex. If only one delimiter character will be
used, Delimiter 2 should be set to “0”. If the delimiter will be a two-character sequence, use
Delimiter 2 to define the second character. To disable the use of delimiters, set both Delimiter 1
and Delimiter 2 to “0”.
Note that data packing is not only controlled by the delimiter; it is also influenced by the module’s
buffer size and the Force transmit field. If the delimiter has not been received by the time the 1K
buffer is full, the module will pack the data for network transmission and clear the buffer. Also, if
the module will also pack data for network transmission if the next byte of data is not received
within the Force transmit time.
ATTENTION
Do not enable Delimiter 2 if Delimiter 1 has been disabled. The delimiter function will not work
properly if Delimiter 2 is enabled without Delimiter 1.
Force transmit
Setting Factory Default Necessity
0 to 65535 ms 0 ms Optional
0: The force transmit timeout is disabled.
1 to 65535: If the module does not receive the next byte of data within the time specified, it will
packed the data in its buffer into the same data frame for network transmission.
The Force transmit field is typically used in conjunction with the Delimiter fields to specify how
data in the module’s buffer is packed for network transmission. When delimiters are used, the
