Connecting the Data Lines
10/100BaseT(X) Ethernet Port Connection
All TN-5308 models have 8 10/100BaseT(X) Ethernet ports (4-pin shielded
M12 connectors with D coding). The 10/100TX ports located on the
TN-5308’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.
