Auto-Negotiation and Speed Sensing
All of the EDS’s RJ45 Ethernet ports independently support
auto-negotiation for speeds in the 10BaseT and 100BaseTX modes, with
operation according to the IEEE 802.3u standard. This means that some
nodes could be operating at 10 Mbps, while at the same time, other nodes
are operating at 100 Mbps. Auto-negotiation takes place when an RJ45
cable connection is made, and then each time a LINK is enabled. The EDS
advertises its capability for using either 10 Mbps or 100 Mbps
transmission speeds, with the device at the other end of the cable
expected to advertise in a similar manner. Depending on what type of
device is connected, this will result in agreement to operate at a speed of
either 10 Mbps or 100 Mbps. If an EDS RJ45 Ethernet port is connected to
a non-negotiating device, it will default to 10 Mbps speed and half-duplex
mode, as required by the IEEE 802.3u standard.
