UP-1200 Presentation Switcher/Scaler
2.2 RJ45
network cable
This system used CAT-5 (five wire) as materials, and
installed RJ45 connectors at both ends of CAT-
5(commonly known as crystal head), thus to connect
the network device. Twisted Pair standard connection
provisions is designed to ensure the layout symmetry
of the cable connector, thus you can make the
interference between the cable connector cancel each
other out. General UTP cable have four pairs of thin
twisted lines and they are marked with different
colors. There are two methods of twisted pair
connection: EIA/TIA 568B standard and EIA/TIA 568A
standard.
