10/100BaseT(X) Ethernet Port Connection
The 10/100BaseT(X) ports located on the EDS-510A’s front panel are used to
connect to Ethernet-enabled devices. Most users configure these ports for
Auto MDI/MDI-X mode, in which case the port’s pinouts are adjusted
automatically 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.
