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.

LED Indicators

The front panel of the

Print Server features

five LED indicators:

Steady or flashing green confirms that the Print Server is powered

.

Link/Act

Steady or flashing green 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 three indicators are also used by the Print Server’s Power-

Setting up the DP-301U

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.





The LED indicator lights up to show that the Print Server is transferring

print data through the USB port.

Confirm proper operation of each of the printers to be connected to the

DP-301U.

1.

When you have confirmed proper operation of each printer, switch its power

OFF

.

2.

Confirm that your network is operating normally.

3.

Connect the DP-301U RJ-45 Connector to the network, using an Ethernet

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 each 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.

8.

Front Panel LED Indicators

Immediately after power-up, all three of the green LEDs should illuminate steadily

for several seconds.

Then the USB LED should flash

ON

three times.

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 USB LED, followed by a darkened LED.

If the Self-Test routine traps 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.

In the event of any such error signal, contact your dealer for

correction of the faulty unit.

When the DP-301U is powered

ON

, 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 USB LED indicator following the Self-Test. Preliminary to the

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

flashing operation.

Getting Started

Below is a sample network using the DP-301U. The DP-301U has a built- in Web-

based management feature that allows users to easily configure and manage

multiple print queues through TCP/IP.

Warning!

Only a USB printer may be connected to the USB port of the

DP-301U. Do not

connect any other USB devices to the USB port of the DP-301U; to do so, may

damage the unit and will void the warranty for this product.

For a list of printers that are compatible with the DP-301U, please see the

Ap-

pendix

in this manual. The compatibility list is not comprehensive. Even if it is

not included in the list,

your printer may be compatible with the DP-301U.

When you entered the default IP address, the main screen of the Print Server’s

configuration will appear (see below).

In addition to the product information, you

can access and control the Print Server’s configuration through four links on the top

of this main screen:

Home,

Configuration

,

Tools

, and

Help

.

Open your web browser and type

in the address box, and

press <Enter>.

This set of numbers is the default IP Address of your Print Server.

Please note that the PC’s IP Address must correspond with the Print Server’s

IP Address in the same segment for the two devices to communicate.
