Introduction

The NexIP Internet Sharing Station is the most cost-effective Internet access solution available today for
users. With only a single Internet account and a low cost dial-up line, it lets a small network of more
than 2 desktop computers to share the vast resource available on the Internet simultaneously. Compare
to traditional leased-line router configuration, the Internet Sharing Station is not only easier to use, it
reduces ownership and maintenance cost dramatically with its innovative architecture. In dial-up
configuration, it connects to remote Internet Service Provider (ISP) network automatically only when local
users tried to access remote hosts on the Internet. To further improve performance when multiple users
access the Internet at the same time, the Internet Sharing Station provides additional asynchronous ports
with dial-on-demand functions. The Internet Sharing Station will dial up additional connections if the
primary line is congested, so the Internet access performance can be improved instantly.

Install the unit

This unit can be placed on a flat surface or mounted on a metallic surface or partition. Please comply with
the following steps for proper installation.

Desktop Installation

y Carefully take out the unit from its packaging
y You will find four self-adhesive rubber feet attached on the bottom of the unit, which provide space

for ventilation and cushion the unit needed against vibrations. Place the unit directly on your desk.

Magnetic Mounting Installation

y Inside each of the four rubber feet, you will find a magnetic ring. Adhere this unit to steel flat surface

using the magnets on the bottom of the unit.

Wall Mounting Installation

y There is a trough on the bottom of the unit, which is used for wall mounting.
y Use two screws to mount the mounting track plate onto the wall.

y Put the unit over the mounting track plate, and slide it to the suitable position.

1. Connecting the Ethernet cable.

Connect a network cable to the Internet Sharing Station’s RJ-45 or BNC port. This unit supports
two types of Ethernet cables: Thin Ethernet (10BASE2, BNC connector) and Twisted Pair
Ethernet (10BASE-T, RJ-45 connector). During power up, the unit automatically detects the type
of network cable and adjusts to that environment.
Note: Please do NOT use both of BNC and RJ-45 connections sim ultaneously.

2. Connect your modem.

Connect an external modem or ISDN TA, using a standard serial cable, to the WAN port on the
back of the unit and to a phone line

Notes:

z Turn off the power before conne cting or disconnecting modems.
z You can connect up to two modems to the Internet Sharing Station

3. Connect the power adapter.

Connect the power adapter to the units. The Power LED should lig ht.

4. Connect the Internet Sharing Station and all of your PCs to hub

Before proceeding this step, make sure each of your PCs has a network interface card installed.

Configuring the Internet Sharing Station

The easiest way to configure the Internet Sharing S tation is to use your existing Web browser. Once you
have set up your PC and installed web browser, you can launch your browser and view web p ages from
the Internet Sharing Station.

 Setting up PC to configure the web
Before using browser to find the web pages from Internet Sharing Station, you have to manually configure

your PC for TCP/IP networking. The DHCP server function of Internet Sharing Station is enabled defaultly,
your PCs should be set to obtain an IP address automatically. This procedure is described in the following
section.

7. Click OK to close the Network Control window.

8. Click OK to close and restart your computer.

To configure other systems

See the documentation for your operating system and set the system up for TCP/IP. Configure the system
to be a DHCP client. If the system doesn’t support DHCP, set an IP address that is not conflicted to that
system and in the range from 192.168.0.1 to 192.168.0.252.

Configuring the Internet Sharing Station

After you finish setting up and restart your computer, you can open web browser, type the following in the
Location (or Addres s) window, and press Ente r.
