Real COM Mode
WE-2100T comes equipped with COM
drivers that work with Windows
95/98/ME/NT/2000/XP/Vista and
UNIX-like systems. The driver establishes
a transparent connection between host and
serial device by mapping the IP:Port of the
WE-2100T’s serial port to a local COM
port on the host computer.
The driver used for Real COM Mode comes with the Network Enabler Administrator which is
installed automatically on your computer when you install the Network Enabler 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 or wireless interface. At the other end of the connection, the WE-2100T accept the WLAN
frame, unpack the TCP/IP packet, and then transparently send it to the appropriate serial device
attached to the WE-2100T’s serial port.
Real COM Mode allows several hosts to have access control of the same WE-2100T. The Moxa
driver that comes with your WE-2100T 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.
RFC2271 Mode
RFC-2217 mode is similar to Real COM mode. That is, a driver is used to establish a transparent connection
between a host computer and a serial device by mapping the serial port on the WE-2100T to a local COM port
on the host computer. RFC2217 defines general COM port control options based on the Telnet protocol. Third
party drivers supporting RFC-2217 are widely available on the Internet and can be used to implement Virtual
COM mapping to your WE-2100T serial port.
