10/100BaseT(X) Ethernet Port Connection
All TN-4916 models have 8 10/100BaseT(X) Ethernet ports (4-pin
shielded M12 connector with D coding). The 10/100TX ports located on
the TN-4916 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/Router-type) connected to the port. In
what follows, we give pinouts for both MDI (NIC-type) ports and MDI-X
(HUB/Switch/Router-type) ports. We also give cable wiring diagrams for
straight-through and cross-over Ethernet cables.
