Users Manual

Crosstalk

Unwanted signal transfer between adjacent cable pairs. Crosstalk occurs because electrical signals passing through a cable pair create an electromagnetic field that transmits the signal to nearby pairs.

CSV Data

Abbreviation for comma-separated variable. A list of data separated by commas. When CSV data is loaded into a spreadsheet application, the application puts each comma- separated value into a separate cell.

dB

Abbreviation for decibel. A logarithmic unit used for expressing the loss or gain of signal strength.

To transfer data from a computer to a remote device.

EIA 568A

Electronic Industries Association Commercial Building Telecommunications wiring standard. Specifies maximum cable lengths, installation practices, and performance specifications for generic building wiring.

Ethernet

A local area network protocol using Carrier Sense Multiple Access with Collision Detection (CSMA/CD). Ethernet is available with four cabling alternatives: thin coaxial, standard (thick) coaxial, twisted pair, and fiber optic. This protocol uses 10 Mb/s baseband transmission and is defined by the IEEE standard 802.3.

Flash Memory

Computer memory that requires no power to maintain its contents, yet, unlike ROM, can be reprogrammed while installed in a system.

Foil-Screened Twisted Pair (FTP)
