Real COM Mode
NE-4100 Series boards come equipped with COM drivers that work with Windows 95/98/ME/NT/2000/XP systems. The driver establishes a transparent connection between host and serial device by mapping the IP:Port of the NE-4100 Series boards’ serial port to a local COM port on the host computer.
The driver used for Real COM Mode comes with the NE-4100 Series Windows Administrator which is installed automatically on your computer when you install the NE-4100 Series Administration Suite.
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 NE-4100 Series boards accept the Ethernet frame, unpack the TCP/IP packet, and then transparently send it to the appropriate serial device attached to the NE-4100 Series boards’ serial port.
Real COM Mode allows several hosts to have access control of the same NE-4100 Series board. The Moxa driver that comes with your NE-4100 Series controls host access to attached serial devices by checking the host’s IP address.
Modify the Accessible IP Setting table when a public IP address is required for your application.
