10/100BaseTx Ethernet Port Connection
The 10/100BaseTX ports located on MOXA EtherDevice Server's front panel are used to
connect to Ethernet-enabled devices. Most users will choose to configure these ports for
Auto MDI/MDI-X mode, in which case the port's pinouts are automatically adjusted
depending on the type of Ethernet cable used (straight-through or cross-over), and the type
of device (NIC-type or HUB/Switch-type) connected to the port.
In what follows, we give pinouts for both MDI (NIC-type) ports and MDI-X
(HUB/Switch-type) ports. We also give cable wiring diagrams for straight-through and
cross-over Ethernet cables.
