APPENDIX A  Cable Information

This cable information is provided for your reference only.  Please ensure you only connect the appropriate 
cable into the correct socket on either this product or your computer.

RJ-45 Network Ports

RJ-45 Network Ports can connect any networking devices that use a standard LAN interface, such as a Hub/
Switch Hub or Router. Use unshielded twisted-pair (UTP) or shield twisted-pair (STP) cable to connect the 
networking device to the RJ-45 Ethernet port.   Depending on the type of connection, 10Mbps or 100Mbps, 
use the following Ethernet cable, as prescribed.

10Mbps:

Use EIA/TIA-568-100-Category 3, 4 or 5 cable.

100Mbps:

Use EIA/TIA-568-100-Category 5 cable.

Straight and crossover cable configuration

There are two types of the wiring: Straight-Through Cables and Crossover Cables. Category 5 UTP/STP cable 
has eight wires inside the sheath. The wires form four pairs. Straight-Through Cables has same pinouts at 
both ends while Crossover Cables has a different pin arrangement at each end.
