Chapter 1 Ethernet Module (EN311) Overview

1.2 Standards and Terminology

Generally, both the Ethernet Version 2.0 (DIX standard) established by the three
companies (DEC, Intel, and Xerox) and the ISO8802-3(IEEE802.3) which has been
internationally standardized based on the DIX standard are called the "Ethernet".
Because ISO8802-3 standard includes the DIX standard, the network devices developed
according to each standard are basically compatible.
Because the physical layer of the EN311 has a configuration compliant with the
ISO8802-3, ISO8802-3 compliant network devices should be used.
Also note that the data link layer of the EN311(send/receive frame of the IP datagram)
adopts the DIX standard frame (see Figure 6-8).
The network terms used throughout this guide are the ones used in the ISO8802-3
standard. The DIX standard terms (colloquial terms) and the ISO8802-3 standard
network terms are mapped as follows:
