Choosing the Proper Operation Mode

TCP Client Mode

In TCP Client mode, NE-4100 Series boards can actively establish a TCP connection to a pre-defined host computer when serial data arrives.

After the data has been transferred, NE-4100 Series boards 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 NE-4100 Series board running TCP Client Mode actively establishes a connection based on the conditions set in the firmware. You can let the NE-4100 board 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 NE-4100 board, and from the NE-4100 board 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.
