NE-4100 Series User’s Manual Web Console Configuration
6-10
The Inactivity time should at least be set larger than that of Force Transmit timeout. To prevent the
unintended loss of data due a session getting disconnected, it is highly recommended that this value is
set large enough so that the intended data transfer is completed.
Max connection
Setting Factory Default Necessity
1, 2, 3, 4 1 Required
Max connection is usually used when the user needs to receive data from different hosts
simultaneously. The factory default only allows 1 connection at a time.
Max. connection 1:
WE-2100T only allows 1 host to open the TCP connection to the specific serial port.
Max connection 2 to 4:
Allows requests from between 2 and 4 host’s TCP connection to open the specific WE-2100T
serial port, at the same time. When multiple hosts establish a TCP connection to the specific serial
port at the same time, WE-2100T will duplicate the serial data and transmit to all of the hosts.
Ethernet data is sent on a first-in-first-out basis to the serial port when data comes into WE-2100T
from the Ethernet interface.
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
Once the WE-2100T receives both delimiters through its serial port, it immediately packs all data
currently in its buffer and sends it out the WE-2100T’s Ethernet port.
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 1K, the WE-2100T 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.
Force transmit
Setting Factory Default Necessity
0 to 65535 ms 0 ms Optional
0: Disable the force transmit timeout.
1 to 65535: Forces the WE-2100T’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 WE-2100T fetches the serial data from its
internal buffer. If data is being received through the serial port, the WE-2100T stores the data in
its internal buffer. WE-2100T 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 as Force
Transmit timeout.
Optimal force transmit timeout differs according to your application, but it must be at least as
large as one character interval within the specified baud rate. For example, assume that the serial
port is set to 1200 bps, 8 data bits, 1 stop bit, and no for parity. In this case, the total number of
bits required to send a character is 10 bits and the time required to transfer one character is
