2.4 Auto
Negotiation
The Industrial Switch’s 10/100Mbps switched RJ-45 ports auto negotiates with
connected devices to determine the fastest data transmission rate supported by
both devices. This helps make the Switch a plug and play device. The Switch’s
RJ-45 ports support full or half duplex, depending on which transmission speed is
supported by the attached device.

2.5 Switching,
Filtering
Packets entering the Industrial Switch with source and destination addresses
belonging to the same port segment will be filtered, limiting those packets to one
port, and relieving the rest of the network from the need to process them. A packet
with a destination address served by another port segment will be forwarded to the
appropriate port, and will not be sent to the other ports where it is not needed.
Packets that are used to maintain network operations (such as the occasional multi
cast packet) are forwarded to all ports.
The Industrial Switch operates in the store and forward switching mode, which
eliminates bad packets and enables peak performance to be achieved when there is
heavy traffic on the network.

2.6
Port Speed & Duplex Mode
After a cable is plugged into a specific port, the system uses auto negotiation to
determine the transmission mode for the new twisted pair connection:
If the connected device does not support auto negotiation or has auto negotiation
disabled, an auto sensing process is initiated to select the speed and set the duplex
mode to half duplex.
