TCP Client Mode
In TCP Client mode, WE-2100T can actively
establish a TCP connection to a set of (max. 4)
pre-defined host computer when serial data
arrives.
After the data has been transferred, WE-2100T
can automatically disconnect from the host
computer by using the TCP alive check time or
Inactivity time settings. Refer to the following
chapters for more details.
As illustrated in the figure, data transmission
proceeds as follows:
1. The WE-2100T running TCP Client Mode
actively establishes a connection based on
the conditions set in the firmware. You can
let the WE-2100T connect to a remote host
on start up, or connect later when data from
serial device arrives.
2. Once the connection is established, data can
be transmitted in both directions—from the
host to the WE-2100T, and from the
WE-2100T to the host.
UDP Mode
Compared to TCP communication, UDP is
faster and more efficient. In UDP mode,
you can multicast data from the serial
device to multiple host computers, and the
serial device can also receive data from
multiple host computers, making this mode
ideal for message display applications.
