Auto MDI/MDI-X Connection
The Auto MDI/MDI-X function allows users to connect MOXA Industrial
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 IMC to Ethernet devices.
Dual Speed Functionality and
Switching
MOXA Industrial 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 MOXA
Industrial 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 MOXA Industrial 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. MOXA Industrial 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 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 Industrial Media Converter 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.
