Rfc2217 Mode; Udp Mode - Moxa Technologies MiiNePort E2-H User Manual

MiiNePort E2/E3

RFC2217 Mode

RFC2217 is an industrial public protocol for sharing serial devices over TCP/IP Ethernet networks. RFC2217 is
similar to Moxa's proprietary Real COM mode in that it 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.

UDP Mode

UDP is similar to TCP but is faster and more efficient. Although data can be broadcast to or received from
multiple network hosts, UDP does not support data verification, and consequently is not suitable for
applications for which data integrity is critical. UDP would, however, be suitable for message display
applications.
