DI-1750 Router
Connecting the Fast Ethernet Interface
The Fast Ethernet port of the router provides a STP (RJ45) interface and ACT, Link, 100Mbps LED indicators. The STP
LAN interface port supports 10/100Mbps auto-negotiation speed. A Hub/Switch can be connected through the router's STP
Port using a CAT5 UTP/STP cable. The UTP pin numbering is shown in the following figure.
The connection between 10/100Mbps auto-negotiation Ethernet Port and the Hub/Switch is illustrated in the following figure.
UTP Port (twist-pair) pin description table:
The UTP Port can be connected to a Hub/Switch through a Category 5 twisted-pair cable. The connection is illustrated in the
following figure.
When connecting the DI-1750 Router directly to Ethernet port of single host computer, a UTP cross-over cable can be used.
Thus you can eliminate the Fast-Ethernet Hub/Switch in the connection example above. But, when you need to connect more
than one computer to the router, you must use an Ethernet Hub or switch. The illustration of the UTP cross -over connection is
:
showed as following
Note: The color code of the twisted-pair cable connection should comply with EIA/TIA 568A/B standard.
