Grounding the EDS-305-M12
Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). Run the ground connection from the
ground screw to the grounding surface prior to connecting devices.
EDS-305-M12
ATTENTION
This product is intended to be mounted to a well-grounded
mounting surface such as a metal panel.
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.
