10/100Base-T Ethernet port
The 10/100BaseT(X) ports located on facility front panel. The PIN define of RJ45 port display as
follows, Connect by UTP or STP. The connect distance is no more than 100m. 100Mbps is used
100 Ω of UTP 5, 10Mbps is used 100 Ω of UTP 3, 4, 5.
RJ 45 port support automatic MDI/MDI-X operation. Can connect the PC, Server, Converter and
HUB by straight–though cable. Pin 1,2,3,6 Communication connect in MDI. 1→3, 2→6, 3→1,
6→2 are used as cross-over cable in the MDI-X port of
Converter and HUB.
10Base-T/100Base-TX are used in MDI/MDI-X, the PIN define in the table as below.
