UTP cable (RJ-45 connector)
The 10Base-T, RJ-45 out jack is used to connect a 10Base-T Ethernet device via a
2-pair UTP cable. (Use category 3, 4, or 5 UTP cable.) The length of the UTP
cable can be up to 100m (328ft).
The RJ-45 connector pin configuration is shown in Figure 5. The pin assignments
are show in the Table 2..

Wiring schemes for UTP cable and devices
How to install the UTP cable is determined by the characteristics of the 10Base-T UTP
port of the other device. The following shows some pinning examples:
Note: The device 10Base-T output jack is normally used to connect to another
10Base-T device. The vendor's 10Base-T device sometimes provides a
crossover option to set the jack as an input jack for connecting to a 10Base-T
Ethernet station.
