Moxa Technologies NPort 5600 Series User’s Manual, Choosing the Proper Operation Mode

NPort 5600 Series User’s Manual Choosing the Proper Operation Mode

The driver used for Real COM Mode comes with the NPort Windows Administrator which will install 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.

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

Refer to Accessible IP Settings in Chapter 5 for more details.
