.

The LED indicator lights up to show that thePrint

Server is transferring print data through the USB port.

Ethernet/WLAN

Steady or flashing green light confirms that the Print Server has a good

connection to the Ethernet or Fast Ethernet network.

The indicator blinks off briefly to indicate that the Print Server is

receiving or transmitting from the network.

These four indicators are also used by the Print Server’s Power-

Self Test

(POST) to indicate any hardware failures.

Network Cable Connector

The Print Server’s rear panel features an RJ-45 connector for

connection to 10Base-T Ethernet cabling or 100Base-TX Fast

Ethernet cabling (which should be Category 5 twisted-pair cable).

The port supports the NWay protocol, allowing the Print Server to

automatically detect or negotiate the transmission speed of the

network.

DC Power Connector

The DC power input connector is located on the Print Server’s

rear panel and is labeled DC 5V.

D-Link

wireless products are based on industry standards to provide easy-to-use

and compatible high-speed wireless connectivity within your home, business or

public access wireless networks. D-Link wireless products will allow you access to

the data you want, when and where you want it. You will be able to enjoy the

freedom that wireless networking brings.

A WLAN is a cellular computer network that transmits and receives data with radio

signals instead of wires. WLANs are used increasingly in both home and office

environments, and public areas such as airports, coffee shops and universities.

Innovative ways to utilize WLAN technology are helping people to work and

communicate more efficiently. Increased mobility and the absence of cabling and

other fixed infrastructure have proven to be beneficial for many users.

Wireless users can use the same applications they use on a wired network.

Wireless adapter cards used on laptop and desktop systems support the same

protocols as Ethernet adapter cards.

Wireless Basics

People use wireless LAN technology for many different purposes:

Mobility

-

Productivity increases when people have access to data in any location

within the operating range of the WLAN.

Management decisions based on real-

time information can significantly improve worker efficiency.

Low Implementation Costs

–

WLANs are easy to set up, manage, change and

relocate. Networks that frequently change can benefit from WLANs ease of

implementation. WLANs can operate in locations where installation of wiring may

be impractical.

Installation and Network Expansion

- Installing a WLAN system can be fast and

easy and can eliminate the need to pull cable through walls and ceilings. Wireless

technology allows the network to go where wires cannot go - even outside the

home or office.

Scalability

– WLANs can be configured in a variety of topologies to meet the needs

of specific applications and installations. Configurations are easily changed and

range from peer-to-peer networks suitable for a small number of users to larger

infrastructure networks to accommodate hundreds or thousands of users,

depending on the number of wireless devices deployed.

Inexpensive Solution

- Wireless network devices are as competitively priced as

conventional Ethernet network devices.

Standards-Based Technology

Based on the IEEE

802.11b

standard, the DP-311U is

interoperable with existing

compatible 2.4GHz wireless technology with data transfer speeds of up to 11Mbps

when used with other D-Link

Air

devices.

Wireless Basics (cont.)

Installation Considerations

The D-Link

Air

DP-311U lets you print through your network, using a wireless

connection, from virtually anywhere within its operating range. Keep in mind,

however, that the number, thickness and location of walls, ceilings, or other objects

that the wireless signals must pass through, may limit the range. Typical ranges

vary depending on the types of materials and background RF (radio frequency)

noise in your home or business. The key to maximizing wireless range is to follow

these basic guidelines:

Keep the number of walls and ceilings between the DP-311U and other

network devices

to a minimum - each wall or ceiling can reduce your D-Link

wireless product’s range from 3-90 feet (1-30 meters.) Position your

devices

so that the number of walls or ceilings is minimized.

2.

Be aware of the direct line between network devices. A wall that is 1.5 feet thick

(.5 meters), at a 45-degree angle appears to be almost 3 feet (1 meter) thick. At

a 2-degree angle it looks over 42 feet (14 meters).

Position devices so that the

signal will travel straight through a wall or ceiling (instead of at an angle) for

better reception.

3.

Keep your product away (at least 3-6 feet or 1-2 meters) from electrical

devices or appliances that generate extreme RF noise.

5.

Building Materials can impede the wireless signal - a solid metal door or

aluminum studs may have a negative effect on range. Try to position wireless

devices and computers with wireless adapters so that the signal passes

through drywall or open doorways and not other materials.

4.

Keep the antenna of the DP-311U in an upright position

Setting up the DP-311U

Installing the Print Server

WARNING:

Configuration problems may result if the Print Server is powered up without

first establishing its network connection. Follow this procedure to avoid complications at

the configuration stage.

Confirm proper operation of the printer to be connected to the DP-311U,

1.

When you have confirmed proper operation of the USB printer, switch it the

power

OFF

.

2.

Confirm that your network is operating normally.

3.

Connect the DP-311U RJ-45 Connector to the network, using a straight

through CAT5 cable..

4.

While the printer is powered

OFF

, install the USB printer cable to connect the

printer’s USB port to the USB port of the Print Server.

5.

Switch on the connected printer.

6.

Plug the AC power adapter’s DC output plug into the DC 5V power socket on

the rear panel of the Print Server.

7.

Plug the power adapter into a power outlet. This will supply power to the Print

Server, as it has no external power switch. The green Power LED on the

Print Server’s front panel should illuminate steadily, and the Print Server’s

Self-Test will proceed.
