automatically keeps up with new node locations. An address-aging algorithm causes the least-used
addresses to be deleted in favor of newer, more frequently used addresses. To reset the address
buffer, power down the unit and then power it back up.
Auto-Negotiation and Speed Sensing
All of MOXA EtherDevice Switch’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. MOXA EtherDevice Switch 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 similarly
advertise. 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 a MOXA EtherDevice Switch 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.
