6 Appendix B - Cabling Considerations
This Appendix describes the pin-to-pin connections for cables used with the TA7102i.
Warning: To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line
cord.
6.1 RJ-45 Cable
The RJ-45 connector is commonly used for network cabling and for telephony applications. It is
used to wire both ends identically so the signals pass straight through. RJ-45 cabling is also
known as Twisted-pair Ethernet (TPE), Unshielded twisted pair (UTP) and 10/100 Base-T.
Figure 6: RJ-45 Cable
hen connecting an Ethernet cable to the TA7102i, use a standard telecommunication cord with
a minimum of 26 AWG wire size. It is possible to use either a crossover or straight Ethernet
cable to connect in the Ethernet connectors. These connectors perform automatic MDI / MDIX
detection, meaning that they adapt to the type of cable connected to them.
The auto MDI / MDIX feature works only when the connectors are configured in auto detect
mode, which is the default mode.
Whenever you force the TA7102i to use a specific Ethernet mode (for example 100 Mb Full
Duplex), the type of cable to use depends on the other peer. For example, a straight cable is
required to connect the TA7102i to a hub or a switch, while a crossover cable is required to
connect the TA7102i to a PC.
Straight Through Cable
A RJ-45 straight through cable is used to connect a computer to a network device. For instance,
you must use straight through cables to connect a computer to a network hub, switch, and
router.
