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:

UTP Cable Pin Wiring

Pin	Pin
1	1

Transceiver	2	2	10Base-T Device Input
	3	3
	6	6
	Pin	Pin
	1	3	￿	10Base-T Output Jack
Transceiver	2	6	￿	Computer 10Base-T Port
	3	1	￿	Transceiver
	6	2

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.
