NPort 5400 Series User’s Manual

Choosing the Proper Operation Mode

ATTENTION

The driver used for Real COM Mode comes with the NPort Windows Administrator. The driver is installed automatically on your computer when you install NPort Administration Suite.

The important point is that Real COM Mode allows users to continue using RS-232/422/485 serial communications software that was written for pure serial communications applications. The driver intercepts data sent to the host’s COM port, packs it into a TCP/IP packet, and then redirects it through the host’s Ethernet card. At the other end of the connection, the NPort accepts the Ethernet frame, unpacks the TCP/IP packet, and then transparently sends it to the appropriate serial device attached to one of the NPort’s serial ports.

ATTENTION

Real COM Mode allows several hosts to have access control over the same NPort. The driver that comes with your NPort controls host access to attached serial devices by checking the host’s IP address.

Modify the Accessible IP Setting table when the legal IP address should be required in your application

TCP Server Mode

In TCP Server mode, the NPort provides a unique IP:Port address on a TCP/IP network. The NPort waits passively to be contacted by the host computer, allowing the host computer to establish a connection with and get data from the serial device. This operation mode also supports up to 4 simultaneous connections, so that multiple hosts can collect data from the same serial device—at the same time.

As illustrated in the figure, data transmission proceeds as follows:

1.The host requests a connection from the NPort configured for TCP Server Mode.

2.Once the connection is established, data can be transmitted in both directions—from the host to the NPort, and from the NPort to the host.
