Crestron CAT5 Wiring Reference Guide
Crestron CAT5 Wiring
Introduction
Category 5 (CAT5) wiring is a twisted pair cable designed for Ethernet networks.
These networks operate at speeds of up to 100 Megabits per second (Mbps) using the
100baseT standard. Crestron®takes advantage of this specification for a variety of
audio and video applications. This document contains basic CAT5 information and
specific wiring connections for Crestron audio and video CAT5 devices.
The term “Category” refers to the classifications of UTP (unshielded twisted pair)
cables. The differences in the classification of the cables are their electrical
performance criteria. ANSI/EIA (American National Standards Institute/Electronic
Industries Association) Standard 568 is one of several standards that specify these
categories of twisted pair cabling systems, which includes wires, junctions, cable
material and connectors, in terms of the data rates that they can sustain. There are
currently three main Categories of cable - Category 3, Category 4, and Category 5.
• Category 3 = Rated to 16 MHz (used for Ethernet 10BaseT)
• Category 4 = Rated to 20 MHz (used for Token-Ring, 10BaseT)
• Category 5 = Rated to 100 MHz (used for 100BaseT, 10BaseT)
Under the 10BaseT/100BaseT (twisted pair) standard, the distance between
connected components cannot exceed 328 feet (100 meters).
In large Ethernet configurations, Crestron recommends the use of a hub or switch for
signal distribution. Generally, in a hub system every device must have a separate
wire returning to a central point.
CAT5 wire is typically four pairs of 24AWG solid copper wires, with each pair
twisted about three times per inch. It can be supplied with or without a foil shield,
and with various outer insulation materials.
CAT5E (enhanced) is essentially the same as CAT5, however it is made to higher
electrical standards.
NOTE: Special plenum cable is required if you are running the wire in heating
system plenums or in certain commercial settings.

Electrical Measurements of CAT5E Wiring
The specifications for CAT5E wiring can vary within a range as specified by
TIA/EIA. These specifications depend on the kind of connections (permanent,
patchcords, etc.), the length of cable run, and the type of termination connectors. The
following are a list of measurements that are made on CAT5E cables.
• Attenuation is a measure of signal loss from one end of a cable to the
other, and is measured in each pair of wires.
• NEXT (Near End Cross Talk) is a measurement of noise that is coupled
from an adjacent pair of wires, usually the receiving pair and the
transmitting pair. NEXT is measured for all pair combinations.
• PSNEXT (Power Sum NEXT) is the measurement of one pair while all the
other pairs are in use. This calculation is made for each pair in the cable.
• Delay Skew (Propagation Delay) is the measurement of signal speed
through the wires. All the wires of the cable are fed the same signal
simultaneously. The time difference at the receiving end of each wire is
measured, and the shortest time is subtracted from the longest time.
• FEXT (Far End Cross Talk) is measured by transmitting on one pair and
measuring cross talk on an adjacent pair at the far end of the cable.
• ELFEXT (Equal Level Far End Cross Talk) is FEXT minus Attenuation.
• PSELFEXT (Power Sum ELFEXT) uses all wires in the cable.
• ACR (Attenuation to Cross Talk Ratio) is a measurement of the ratio of
signal to noise and reveals the bandwidth of the cable. It is derived by the
difference between NEXT and Attenuation.
Installation Notes
• Never pull CAT5 wire with excessive force. The CAT5 tension limitation is
25 lbs, much lower than standard audio/video cable.
• Never step on or crush, kink, or crimp CAT5.
• Avoid periodic sags; vary the intervals if the cable must sag.
• Do not bend CAT5 wire tightly around a corner; ensure that it bends
gradually, so that a whole circle would be at least two inches in diameter.
• Do not allow knots or kinks, even temporarily.
• When using conduit, do not fill to more than 40% if using more than two
cables (National Electrical Code, Chapter 9, Table 1).
• Never untwist the two wires in a single pair for more than 1/3-1/2"
(0.84 – 1.27 cm) when making a connection (the twists are critical to
canceling out interference between the wires).
• Never run CAT5 parallel to power wiring closer than six inches.
• Avoid splices. Every splice degrades the line.

CAT5 Pin and Color Specifications
There are two standards for CAT5 wiring, TIA-568B and TIA-568A.
TIA-568B is a straight-through connection. The signals on pins 1 through 8 are
identical on both ends of the cable.
TIA-568A is a straight-through connection. The signals on pins 1 through 8 are
identical on both ends of the cable. However, the orange and green pairs of wires
exchange pair numbers and are connected to different pins than TIA-568B.
NOTE: To determine which pin is number 1, hold the cable so that the end of the
eight pin modular plug is facing toward you, with clip down and copper side up.
When looking down at the copper connections, pin 1 will be on the far right.
NOTE: Do not confuse pair numbers with pin numbers. A pair number is used for
reference only (e.g., 10BaseT Ethernet uses pairs 2 & 3). The pin numbers indicate
actual physical locations on the plug and jack.

CAT5 Cable Pairs
The CAT5 twisted cable pairs are color-coded; the pair colors depend on which EIA
specification is used, TIA-568B or TIA-568A.

White/Blue White/BluePair 1 Blue Blue
White/Orange White/GreenPair 2 Orange Green
White/Green White/OrangePair 3 Green Orange
White/Brown White/Brown
Pair 4 Brown Brown
NOTE: Because of their identical pair groupings, cables terminated with either
T568A or T568B pair assignments may be used interchangeably, provided that both
ends are terminated with the same pin/pair scheme.

Audio Applications
NOTE: Balanced audio does not require a shield if the cable has good common
mode characteristics (such as CAT5). Unbalanced audio signals are sent on a single
wire, using ground as the reference for the signal. Ground wires are problematic
because they can carry current when exposed to electromagnetic fields or when there
is a voltage difference between the two connecting pieces of equipment. Balanced
audio uses two signal wires. The signal and its complement are sent down the
twisted pair together. Any noise picked up tends to be of equal amplitude and in
phase on both wires. At the receiver, the two signals are subtracted, and noise is
cancelled out. This technique is called common mode rejection.

Connect the TPS-IMC-BV to the CNX-BIPAD8 using the Crestron TPS Audio
cable. Audio on both channels will work properly when connecting the TPS panel
and the TPS-IMC-BV and using a standard EIA 568B CAT5 cable between
CNX-BIPAD8 and TPS-IMC-BV.
When connecting the CNX-BIPAD8 direct to the TPS touchpanel (not using the
TPS-IMC-BV) using a standard CAT5 cable or Crestron TPS Audio cable, only the
audio on the right channel will operate.
