NPort 6000 Series User’s Manual Introducing Serial Port Operation Modes

4-4

TCP Server and Secure TCP Server Modes

In TCP Server mode, the serial port on the NPort

6000 is assigned a port number which must not

conflict with any other serial port on the NPort

6000. The host computer initiates contact with the

NPort 6000, establishes the connection, and

receives data from the serial device. This operation

mode also supports up to 8 simultaneous

connections, enabling multiple hosts to collect data

from the same serial device at the same time.

As illustrated in the figure, data transmission

proceeds as follows:

The host requests a connection from the NPort

6000, which is configured for TCP Server mode.

Once the connection is established, data can be

transmitted in both directions between the host and

the NPort 6000.

TCP Server mode includes optional data

encryption using SSL.

TCP Client and Secure TCP Client Modes

In TCP Client mode, the NPort 6000 can actively

establish a TCP connection to a pre-defined host

computer when serial data arrives.

After the data has been transferred, the NPort 6000

can automatically disconnect from the host

computer by using the Inactivity time settings.

As illustrated in the figure, data transmission

proceeds as follows:

The NPort 6000, configured for TCP Client mode,

requests a connection from the host.
