QUICK INSTALLATION
This section takes you through a step-by-step minimum installation
and setup procedure for the internet/print server. Please refer to the
main text of this manual for detailed information about the setup
and operation of this device.
Getting Started
Step 1: Unpack the device. Make certain no components have
been lost or damaged. A packing list is provided on page 11.
Step 2: Choose an installation site on a flat, level surface or wall
near the modem or ISDN/TA you plan to use for internet
connections or near the network line you plan to use for a
LAN connection, and near the printer you would like to
share through the server. Note that the internet/print
server can be hung on a wall using the wall mounting
equipment included with the product.
Making Connections
Step 3: Connect the internet/print server to your LAN using a
Category 3, 4 or 5, twisted-pair cable and the device’s single
RJ-45 LAN port. This connection should be made to an
Ethernet or Fast Ethernet switch or hub. (The RJ-45 port
looks like a phone jack.)
Quick Installation 1
Internet/Print Server User’s Guide
Step 4: Connect the internet/print server to the printer using the
LPT port and a parallel cable. See Chapter “Print Server
Setup” for information on how to setup the print server settings and see the IS Admin User’s Guide for information on
shared print services.
Step 5: Connect the internet/print server to a modem or ISDN/TA
using the device’s serial port (COM). (Note that your modem or ISDN/TA should already be connected and setup
according to the instructions included with it.)
Step 6: Plug the power adapter into the device and into an outlet.
Quick Installation2
Configuration
Step 7: Before you can use your internet/print server, IP addresses
on your LAN’s PCs must be set so that they are compatible
with the internet/print server’s settings. The internet/print
server comes with the default local IP address: 192.168.100.1
and the default subnet mask setting: 255.255.255.0. Assum-
ing that you leave these settings unchanged and assign fixed
IP addresses to machines on your LAN that will access the
Internet through the internet/print server, you must give
those machines IP addresses in the range of 192.168.100.xxx,
where xxx is a number from 2 to 255. (If you want to use a
different IP address range, see “Setting IP Addresses” on
page 21.) You can, alternatively, set the machines on your
LAN to obtain their IP addresses automatically using DHCP
to get IP addresses from the internet/print server. Whether
the machines use fixed IP addresses or DHCP, they must all
use the same subnet mask setting as the internet/print
server, and the internet/print server’s local (LAN) IP address must be set as each machine’s default gateway.
Step 8: The internet/print server can be configured and operated
via Telnet or a web browser once PC IP addresses have been
properly set. (Note that some device settings can be manipulated using the IS Admin program included with the device.)
Start your Telnet or browser software and enter the IP address of the internet/print server (either the default IP listed
above or the new address you assigned using IS Admin).
This should bring up the internet/print server start menu.
See the next series of steps for information about settings
that must be set for the device to work properly.
Quick Installation 3
Internet/Print Server User’s Guide
Mandatory Settings for Internet Access
Step 9: ISP Account -> Phone Number, when you signed-up for
an account with your ISP (internet service provider), you
should have been given an access phone number that your
modem will dial. Look under the “WAN Port Settings”
menu for this setting and enter the phone number provider
by your ISP.
Step 10: ISP Account -> User ID, your ISP should also have
assigned a User ID (aka, a username) that you will use for
logging-in. Also under “WAN Port Settings,” enter this user
ID exactly as it was provided to you.
Step 11: ISP Account -> Password, finally, to complete the ISP
login process, the internet/print server must provide the
password associated with the user ID assigned by your ISP.
Enter it.
You have now completed the basic steps necessary to install, configure, and begin using the internet/print server. Note that, with
respect to steps 9–11, it may be necessary for you to use a “Login
Script” instead. If you enter the information required in those three
settings correctly and still have trouble logging-in, see the “Login
Script” section on page 30 to create a login script.

Internet Server Technology
The concept behind internet servers is to provide internet access for
multiple users through a single internet account. Without an internet server, each end node (i.e., PC or workstation) on a LAN must
have it’s own public domain (global) IP address.
Single Global
PC
(single
end user)
IP Address
176.220.22.1
Using an internet server allows a single global IP address to be
shared by multiple end nodes simultaneously.
Introduction8
In this implementation, it is only necessary to pay for a single
internet account even though many people will be able to use it.
Non-Internet Implementations
An internet server can also be used to expand a LAN by creating a
localized IP “sub-group”. In this LAN-to-LAN configuration, the
internet server links the two IP subgroups (as shown below). This
implementation is useful when the LAN has run out of IP addresses.
The internet server uses a single IP address from the first (global)
LAN to establish a second (local) LAN, in much the same way it allows many users to connect to the internet through a single IP
address. PC’s on the second LAN (called a local LAN since the IP
addresses of computers on this LAN are managed by the internet
server) can still access the internet by setting their Gateway address
to the IP address of the local LAN port of the Internet server. Please

Port Description
DP-802 Rear Panel
Installation 13
Internet/Print Server User’s Guide
Serial – WAN
The serial port is used for a WAN connection either to a modem or
an ISDN terminal adapter. The serial port is a standard male 9-pin
RS-232 connector.
Parallel – Printer
The parallel port is used for connecting to a printer for sharing to the
LAN. This port is a standard female 25-pin parallel connector.
RJ-45 – LAN
The internet/print server has a single, NWay RJ-45 LAN port. This
port is 10Mbps and 100Mbps capable (auto-detect, auto-configure)
and designed for use in an Ethernet or Fast Ethernet LAN via a
network hub. The port has standard RJ-45 pinouts.
LED Description
The internet/print server has a small LED array for indicating current port and transmission status. The power/transmit (Pw/Tx) and
connect/receive (Link/Rx) LEDs only relate to activity on the LAN
port. All other LED indicators display information about their related ports as labeled.
Installation14
DP-802 Front Panel / LEDs
Pw/Tx
The Pw/Tx (power/transmit) LED lights when power is supplied to
the device and flashes when the LAN port transmits data.
Link/Rx
The Link/Rx (link/receive) indicator will light up when a good connection is made at the LAN port with an operating and compatible
Ethernet or Fast Ethernet device. This indicator flashes when the
LAN port receives data from the network.
COM
The COM port LED provides an indication of the operating status of
the WAN port. When the WAN port is transmitting data, the COM
port will light. If no data is being transmitted, the COM LED will be
off.
Installation 15
Internet/Print Server User’s Guide
LPT
The LPT port LED lights to indicate when data is being sent to the
network printer it is connected to. If no data is being transmitted,
the LPT LED will be off.
Normal LED Flash Pattern
Immediately after power-up, all four of the LEDs should display
steady green for several seconds. Then the COM LED and LPT LED
should flash simultaneously three times. This sequence of flashes
should be followed by first the COM LED flashing once and then LPT
LED flashing once, repeated three times in succession. If as problem with the device is detected during this time, the LED flashes will
display an error pattern (see Appendix A: Troubleshooting for more
information on POST error indications). If no errors are detected,
the internet server will begin operating normally.
Connecting to the Local Network
The internet/print server includes one RJ-45 NWay LAN port. To
connect the device to your LAN, use a standard Category 3, 4, 5
UTP, or STP twisted-pair cable to link the device to an Ethernet
or Fast Ethernet hub or switch.
Cable length limits must conform to Ethernet and Fast Ethernet
wiring rules. Ethernet cable segments can be a maximum of 100
meters. Fast Ethernet wiring rules also limit the maximum
length of cabling segments to 100 meters.
Once the internet/print server is physically connected to a local
network and you have used the IS Admin software included to assign an IP address to the device (or simply reconfigured your
Installation16
PC’s IP address, subnet mask and gateway to match the default
settings of the internet/print server), you may configure other parameters from your network station using Telnet or a web
browser.
LAN Connection
Installation 17
Internet/Print Server User’s Guide
Connecting to the Internet
The internet/print server must be connected to the internet (this is
also known as a “Wide Area Network or ‘WAN’” connection) using
the COM serial port. The COM port can either be connected to the
serial port of a modem (or fax/modem), or to an ISDN terminal
adapter. The faster the WAN connection is, the faster access will be
and the more users will be able to get on the internet simultaneously.
Connect the COM port of the internet/print server to a modem or
ISDN terminal adapter using a standard serial cable.
