SuperPro Series Installation Manual
Reflection
The abrupt change in direction of a light beam at an interface between two dissimilar
media so that the light beam returns into the media from which it originated.
Refraction
The bending of a beam of light at an interface between two dissimilar media or in a
medium whose refractive index is a continuous function of position, such as graded-
index optical fiber.
RFBus
CEBus acronym for the Radio Frequency Bus.
RGB
(Red, Green &
Blue)
The basic components of the color television system. They are also the primary colors
of light, not to be confused with Cyan, Magenta, and Yellow, the primary pigments.
Ring –
The negative telephone wire. The wire that is mostly a color with a white band.
RJ45
Modular Connector used to terminate 4 pair twisted pair cable.
Router
Directing or routing electronic information packets to a particular network node (network
address). This could be point to point routing or broadcasting to one or all network
media (coax, twisted pair, fiber optics, infrared, or radio frequency).
RS232
A standard connection interface for computer peripheral equipment.
RS422
A standard operating in conjunction with RS-449, which specifies electrical
characteristics for balanced circuits.
SATV
Satellite Antenna Television.
Single Mode
Fiber
Light travels in a single path within the small core diameter. Will only transmit light rays
that enter at a narrow angle but will transmit very wide bandwidth signals.
Site Survey
The part of a requirements survey that is performed on the premises. It focuses on the
building’s structural layout, materials and other conditions that may affect the way the
building’s distribution system should be designed.
Skin Effect
As the frequency used for the transmission increases, the signal current and the
magnetic field that surround it concentrate closer and closer to the outer edge or “skin”
of the conductor, increasing the resistance.
Splice
A permanent joint between two optical waveguides.
STP
Shielded Twisted Pair - Two wires that are loosely wound or twisted around each other
to help cancel out any induced noise in balanced circuits. Multiple pairs of wires are
contained in one sheath, and each wire pair is shielded by another sheath.
Surge
A sudden voltage rise and fall in an electrical circuit.
Surge
Suppression
Process by which transient voltage surges are prevented from reaching sensitive
electronic equipment.
Surround
Sound
This usually implies an audio system with more than two channels of information. The
additional channels provide “ambiance” or sound information that is happening
somewhere other than from the left or right speaker.
Switch
Device used to increase bandwidth efficiency by quickly “switching” data streams, or
cells, directly to the node to which they are addressed.
Systems
Integrator
The Career of the 90’s. An individual who has the talents to oversee several electronic
disciplines, and help them communicate and work together – creating product synergy.
TCP/IP
Transport Control Protocol / Internet Protocol. A protocol specification that conforms to
the latest DOD ARPANET standard. The TCP/IP protocol module corresponds to
layers three and four of the ISO protocol model.
Tip +
The positive phone wire. The wire that is mostly white with a colored band.
Tone
Generator
Tool that has two parts: A transmitter and a receiver. The transmitter inserts a signal
onto a copper cable, emitting a tone when you are close to the wire. This tool is helpful
when the installer failed to label the wires, or you cannot locate wires.
