9-12 Connector Types

The DB9 connector does not perform a wrap on disconnect as does the larger MIC

connector. There is no internal mechanism for performing these operations.

Stations connected to networking hardware with DB9 connectors rely on the

networking hub to perform any wrapping in the event of a disconnection or cable

error.

STP wires that are connected to a DB9 cable must be set up in the fashion detailed

below:

RJ45

The shielded RJ45 connector used with STP cable is identical in shape to the

standard RJ45 connector used in other network applications such as Ethernet and

FDDI TP-PMD. The difference between the shielded RJ45 and the standard RJ45 is

the addition of a metal shielding ground to the plastic housing of the RJ45

connector. This shield is connected to the braided outermost shield of the STP

cable.

The connector itself is a rectangular keyed connector with a locking clip. The RJ45

connector can only be inserted into an RJ45 port in its proper alignment, and,

when inserted, will lock into place. Due to the lighter construction characteristics

of the RJ45 connector in comparison with the other STP cable connectors, care

should be taken to ensure that the strain placed on an RJ45 connection is

minimized through proper use of cable management hardware.
