Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect IE-SW-IP67(T)-
5M12’s 10/100BaseTX ports to any kind of Ethernet device, without
needing to pay attention to the type of Ethernet cable being used for the
connection. This means that you can use either a straight-through cable
or cross-over cable to connect the IE-SW-IP67(T)-5M12 to Ethernet
devices.
Dual Speed Functionality & Switching
The IE-SW-IP67(T)-5M12 10/100 Mbps switched M12 ports auto
negotiate with the connected device to use the fastest data
transmission rate supported by both devices. All of Weidmül
ler’s
unmanaged switches are plug-and-play devices, so that software
configuration is not required. The half/full duplex mode for the switched
M12 ports is user dependent and changes (by auto-negotiation) to full
or half duplex, depending on which transmission speed is supported by
the attached device.
Switching and Address Learning
The IE-SW-IP67(T)-5M12 has an address table that can hold up to
1000 node addresses, which makes it suitable for use with large
networks. The address tables are self-learning, so that as nodes are
added or removed, or moved from one segment to another, the IE-SW-
IP67(T)-5M12 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.
