Console cable
A console cable is an 8-core shielded cable, with a crimped RJ-45 connector at one end for
connecting to the console port of the gateway, and a DB-9 female connector at the other end for
connecting to the serial port on the console terminal.

Ethernet twisted pair cable
An Ethernet twisted pair cable consists of four pairs of insulated wires twisted together. It mainly
transmits analog signals and is advantageous in transmitting data over shorter distances. The
maximum transmission distance is 100 m (328.08 ft).

RJ-45 connector

An Ethernet twisted pair cable connects network devices through the RJ-45 connectors at the two
ends. Figure 2
