Distribution Components

DVI

These high-speed cables have the bandwidth necessary for high-definition

video and are ideal for linking digital signage screens and other equipment.

DVI-D is a digital-only connector. DVI-I supports both digital and analog

RGB connections. DVI-A is used to carry an analog DVI signal to a VGA

device, such as a display. DFP as an early digital-only connector. Dual-link

cables double the power of the transmission up to 9.9 Gbps and support

QXGA resolutions up to 2048 x 1536 at 60 Hz. Single-link cables transmit

up to 4.95 Gbps at 1920 x 1200.

Cabling

DisplayPort

DisplayPort is the newest AV interface. It’s incredibly versatile with the capability

to deliver digital video, audio, graphics, bidirectional communications, and

accessory power over a single connector. DisplayPort is targeted at the

computer world rather than at consumer electronics. It is used to connect

computers, monitors, projectors, etc. DisplayPort connectors are found on

newer computers and displays; the Mini DisplayPort connector is also found

on Apple

products. DisplayPort uses a packetized data structure instead of

a serial one, like DVI and HDMI, so it is not directly backwards compatible.

But DisplayPort ++ (dual-mode) is able to output DVI and HDMI signals

with an adapter.

HDMI

High-Definition Multimedia Interface (HDMI) was the first digital interface

to combine uncompressed high-definition video, up to eight channels of

uncompressed digital audio, and intelligent format and command data in a

single cable. HDMI is the de facto standard for consumer electronics. HDMI

is backward compatible with DVI. Buy only tested cables with the HDMI

logo. This guarantees the cable will perform to specification especially

to ask.

QUESTI

1. What type of connector does your

equipment have?

Currently, the most commonly found connectors on computers,

displays, and projectors are DVI. New computer equipment

will most likely have DisplayPort and/or HDMI connectors.

Older equipment will have VGA connectors. And, home

theater equipment will have HDMI connectors. Take a look

at the connector illustrations on this page to determine

what type of connector you have.

2. Can I mix equipment with different connectors?

Yes and no. If you need to connect a monitor with a VGA

connector to a PC with a DVI-I connector, you can, but you’ll

need an adapter or a cable with both connectors. Adapters also

exist to connect DisplayPort, DVI, HDMI, and VGA equipment.

But, if you run a digital signal from a PC into, say, a switch, it

can’t be converted to analog without an active converter or

scaler. Also, to go from DisplayPort to DualLink DVI you need

active converters.

HD15 VGA

These cables can contain both 28 AWG mini coax

and 24 AWG tinned-copper VGA conductors to

provide support for all control leads, including Pins

9 and 15 for DCC compliance. This cable transmits

analog video signals. It does not support audio.

Coax

Coax cable is used as a transmission line

for radio-frequency signals. It is ideal for AV

distribution and for connecting CCTV, in-house TV systems, radio

transmissions, and surveillance systems. Coax cables are shielded to

prevent EMI interference.

NOTE: The HDMI standards with Ethernet have an additional dedicated data

channel for device networking.

because there is no maximum length

specified in the HDMI standard. And

because longer lengths require a

larger cable, HDMI cables usually have

24–28 AWG copper conductors. For

1080p, Deep Color, or 3D content,

choose High-Speed HDMI cables.
