10/100BaseT(X) Ethernet Port
Connection
All EDS-305-M12 models have 5 10/100BaseT(X) Ethernet ports (4-pin
shielded M12 socket with D coding). The 10/100TX ports located on the
EDS-305-M12’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.
