Rear Panel LED Indicator / Connectors

Power

A steady lit LED indicates proper operation of the Print

Server.

ACT

A steady lit LED indicates proper wired or wireless network

connection. A flicker LED indicates acitivity (configuation or

printing)

LPT

A steady lit LED indicates your Parallel printer is printing.

Network Cable Connector

The Print Server rear panel has a LAN port for CAT5 Ethernet

cabling. 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 connectors 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 wireless LAN (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

802.11g

standard, the DP-G301 is

interoperable with existing

compatible 2.4GHz wireless technology with data transfer speeds of up to 54Mbps*

when used with other D-Link

Air

Plus G

devices.

Installation Considerations

DP-G301 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-G301 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-G301 in an upright position.

* Maximum wireless signal rate based on IEEE Standard 802.11g specifications.

Actual data

throughput will vary.

Network conditions and environmental factors, including volume of network

traffic, building materials and construction, and network overhead lower actual data throughput

rate.

Setting up the DP-G301

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 your printer before connecting the DP-G301.

1.

When you have confirmed proper operation of your printer, turn your

printer power

OFF

.

2.

Confirm that your network is operating normally.

3.

Connect the DP-G301 to your network, using a straight-through CAT5 cable.

4.

While the printer is powered

OFF

, install the DP-G301 parallel port connector

into the parallel port on the network printer.

5.

Switch

ON

your connected printer.

6.

Plug the DC power adapter 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 DP-

G310, 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.

8.

10

Immediately after power-up,

three of the green LEDs should illuminate steadily for

several seconds. Irregularity of

the LED during this LED test may mean there is a

problem with the LED itself.

The actual component tests immediately follow the LED tests. A normal (no fault)

result is signaled by a flashing of the LPT LED, followed by a darkened LED.

If the Self-Test routine detects any component error, then following the LED tests

the Self-Test will halt and the LEDs will continuously signal the error according to

the following table.

When the DP-G301 is powered

, it also automatically performs a Self-Test on

each of its major components. The final result of the Self-Test is signaled by the

state of the LPT LED indicator following the Self-Test. Preliminary to the actual

component tests, the LED indicators are tested to confirm their steady and flashing

operation.
