Auto-Negotiation and Speed Sensing
The EDS’s RJ45 Ethernet ports independently support auto-negotiation
for transmission speeds of 10 Mbps, 100 Mbps, and 1000 Mbps, with
operation according to the IEEE 802.3 standard.
This means that some nodes could be operating at 10 Mbps, while at the
same time, other nodes are operating at 100 Mbps or 1000Mbps.
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 10 Mbps, 100 Mbps, or 1000 Mbps transmission speeds, with the
device at the other end of the cable expected to advertise similarly.
Depending on what type of device is connected, this will result in
agreement to operate at a speed of 10 Mbps, 100 Mbps, or 1000 Mbps.
If an EDS’s 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 802.3 standard.
