Auto-Negotiation and Speed Sensing
All the CSM-G200’s RJ45 Ethernet ports independently support auto-
negotiation for transmission speeds of 10 Mbps, 100 Mbps, and 1000
Mbps in operations, according to the IEEE 802.3u standard.
This means that some nodes could operate at 10 Mbps, while other
nodes are operating at 100 Mbps or 1000 Mbps. Auto-negotiation takes
place when an RJ45 cable connection is made, and then each time a
LINK is enabled. The CSM-G200 indicates its capability for using 10
Mbps, 100 Mbps, or 1000 Mbps transmission speeds; the device at the
other end of the cable is expected to indicate similarly.
Depending on what type of device is connected, this will cause an
agreement to operate at a speed of 10 Mbps, 100 Mbps, or 1000 Mbps.
If the CSM-G200’s RJ45 Ethernet port is connected to a non-negotiating
device, it will default to a speed of 10 Mbps and half-duplex mode, as
required by the IEEE 802.3u standard.
