Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect the Media
Converter’s 10/100BaseTX ports to any kind of Ethernet device,
without paying 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 Media Converter to Ethernet
devices.
Dual Speed Functionality and
Switching
The Media Converter’s 10/100 Mbps RJ45 switched port auto
negotiates with the connected device for the fastest data transmission
rate supported by both devices. All models of Weidmüller Media
Converter are plug-and-play devices, so that software configuration is
not required at installation, or during maintenance. The half/full duplex
mode for the RJ45 switched 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.
Auto-Negotiation and Speed Sensing
All of Weidmüller Media Converter’s RJ45 Ethernet ports
independently support auto-negotiation for transmission speed 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. The Media Converter
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 advertise similarly. 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.
