MiiNePort E1/E2-SDK
Overview
MiiNePort E1/E2-SDK modules act as a bridge to connect your serial devices to the Ethernet. The built-in TCP/IP
stack frees you from the tedious task of programming networking protocols. With one step you can choose the
proper operation mode, and then use your computer to access, manage, and configure your serial devices from
anywhere in the world over the Internet.
Traditional SCADA and data collection systems rely on serial ports (RS-232/422/485) to collect data from a
variety of instruments. Since MiiNePort E1/E2-SDK modules convert between serial and Ethernet signals, your
SCADA and data collection system can be made accessible from any device connected to a standard TCP/IP
network, regardless of whether the devices are used locally or at a remote site.
The MiiNePort E1/E2-SDK supports RealCOM mode and Ethernet Modem mode. You don't need to take effort to
development these two kinds of complex serial to Ethernet operating mode. Only do some setting to complete
the function.
RealCOM Mode
RealCOM mode allows users to continue using software that was written for pure serial communications
applications. Each module comes equipped with COM drivers for Windows systems (95 and above). The
module's serial port is mapped by the driver to an IP address and port number. 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 module accepts the Ethernet frame, unpacks the TCP/IP packet, and then
transparently sends the data to the attached serial device. The driver thus establishes a transparent connection
between the host and serial device, allowing the host to treat the networked device as if it were directly
attached.
ATTENTION
The RealCOM driver comes with the NPort Windows Driver Manager, which is included on the CD-ROM for the
MiiNePort E1/E2-SDK package.
