IE-CS(T)-2TX-xRS232/485
Web Console Configuration
5-15
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 2

00 to FF
None
Optional
Once the IE-CS(T)-2TX-xRS232/485 receives both delimiters through its serial port, it immediately packs all
data currently in its buffer and sends it out the IE-CS(T)-2TX-xRS232/485’s Ethernet port.
Delimiter process
Setting
Factory Default
Necessity
Do Nothing,
Del 1,
Del 2,
Strip Delimiter
Do Nothing
Optional
[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.
Force transmit
Setting
Factory Default
Necessity
0 to 65535 ms
0 ms
Optional
0: Disable the force transmit timeout.
1 to 65535: Forces the IE-CS(T)-2TX-xRS232/485’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 IE-CS(T)-2TX-xRS232/485 fetches the serial data
from its internal buffer. If data is incoming through the serial port, the IE-CS(T)-2TX-xRS232/485 stores the
data in its internal buffer. The IE-CS(T)-2TX-xRS232/485 transmits the 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 the
Force transmit timeout.
The ideal Force transmit timeout depends on your application, but it must be at least larger than a single
character interval within the specified baudrate. For example, assume that the serial port is set to 1200 bps, 8
data bits, 1 stop bit, and no parity. In this case, the total number of bits needed to send a character is 10 bits,
and the time required to transfer one character is
(10 (bits) / 1200 (bits/s)) * 1000 (ms/s) = 8.3 ms.
Therefore, you should set the Force transmit timeout to a value larger than 8.3 ms, so in this case, it must be
greater than or equal to 10 ms.
If a user wants to send a series of characters in the same packet, the serial device attached to the
IE-CS(T)-2TX-xRS232/485 should send that series of characters during a time interval that is less than the
Force transmit timeout for the IE-CS(T)-2TX-xRS232/485, and the total length of data must be less than or
equal to the IE-CS(T)-2TX-xRS232/485’s internal buffer size. The serial communication buffer size for the
IE-CS(T)-2TX-xRS232/485 is 1 KB per port.
