High Definition Multimedia Interface (HDMI)

HDMI transmit audio and video signals in a single digital interface. HDMI connects audio and video

sources such as set-top boxes, DVD players, Blu-ray Disc players, computers, and video game consoles

to compatible digital audio devices, such as computers, monitors, video projectors, and digital televisions.

Advantages of HDMI

• Delivers high-quality audio and video without the loss in quality due to the conversion or

compression of a video or audio signal.

• Delivers smoother and sharper pictures with a distinct reduction in video noise. Sound is crisp and

distortion free.

• Since it is a digital interface, HDMI is compatible with fixed-pixel displays such as LCDs, plasma

displays, and projectors.

Network Connectors

Network connector (RJ-45)

NOTE: The network connector is slightly larger than the modem connector. To avoid damaging the

computer, do not plug a telephone line into the network connector.

Connects the computer to a network. The two lights next to the connector indicate status and activity for

wired network connections.

Modem connector (RJ-11)

Connects the telephone line to the modem connector.

IEEE 1394

The IEEE 1394 interface is a serial bus interface standard and enables simple, low-cost, high-bandwidth

isochronous (real-time) data interaction between computers, peripherals, and consumer electronics

products such as camcorders, VCRs, printers, TVs, and digital cameras. With IEEE 1394-compatible

products and systems, you can transfer video or still images without losing quality.

Key Features

• Digital — Provides better signal quality as it does not require digital-analog-digital conversion.

• Connectivity — Uses a thin serial cable that, through the use of repeaters, can be extended to 100

meters or more over CAT5, fiber optic, or coaxial cables.

• Easy to use — Eliminates the need for special drivers or perform complicated set-ups.

• Hot pluggable — Enables devices to be added and removed while the device and computer are

turned on.

• Flexible — Allows you to connect devices to each other by daisy-chaining them together, without the

need for hubs or switches. Also supports branching, looping, and other topologies, which reduces

cabling complexity. Supports up to 64 devices on a single connection.
