Prior to Installing

This chapter explains what you should do before installing the InfoRanger.

Subscribing Cable Internet Service

The cable modem receives data through a cable TV network. Therefore, it is
necessary to have a cable Internet service to use your cable modem. If you are
already subscribing to cable TV, please make sure that you are also subscribing
to cable Internet service. If you do not have cable Internet service, please
contact your cable TV provider and ask the following services.

z

Whether they support two-way cable modem access service or not.



The InfoRanger enables two-way data transmission. If you want to
use all features of the InfoRanger, you need to subscribe to a cable
TV provider which provides two-way cable modem access service.

z

Whether they provide the Internet service or not.



If you want to send or receive e-mails, access to WWW and/or use other
Internet services through the cable modem, you need to have cable
Internet service. Once you are an Internet service subscriber, your
cable TV provider will provide you with an Internet account, which you
can connect to via your cable modem. Please note that your Internet
account should be established before the installation of cable modem.



, non-condensing)

z

Power Consumption : 10 Watt

z

Input voltage : 100 ~ 240VAC

z

Rated frequency : 50 / 60Hz

While the InfoRanger is operating, the fluctuation range of
input voltage should be whithin 5% of regulated voltage.
Also, the electric outlet which is connected to input terminal
should be grounded.



Avoid static electricity and electric noise….

It may be necessary to use preventive equipment
if the InfoRanger is installed in a place where high
static electricity or electric noise is present.



Clean and well ventilated place….

Install the InfoRanger in a ventilated place where
the appropriate temperature and airflow is present.
As dust can cause a serious failure of operation,
please install the InfoRanger at a clean place.



Avoid the direct rays of light

Direct rays of light can increase temperature of the
InfoRanger and this can cause damage to operational
parts and lead to operation failure. Therefore, it is
recommended to keep the InfoRanger away from direct rays of light.

Connecting PCs

The InfoRanger can be connected to a single PC or to group of PCs by using a
hub or switch. Separate network cables are necessary when you connect PCs
and note that the InfoRanger only provides the straight-through network cable
for a single PC connection. If connecting more than one PC then separate
cables should be prepared.

Single PC Connection

First, turn off the PC, which you will connect to the InfoRanger. Using the RJ­45 network cable (provided with the InfoRanger), connect the

ETHERNET

port of the InfoRanger to the port of the network interface card on the PC.

Using the InfoRanger

This chapter explains features of the LEDs and the connectors at the front and
back of the InfoRanger.

Front Panel

The front panel of the InfoRanger has 6 LED indicator lights that signal the
operating status of the InfoRanger.

Figure 4-1 Front panel of the InfoRanger

When the power adapter is connected to the InfoRanger, the
InfoRanger processes Self diagnosis Î Initialization for
receiving Î Initialization for sending Î Registering modem
and Authentificating services. While these processes are
running, the POWER LED blinks sequentially from the far
most left to the fourth SERVICE LED. When this process is
complete and the InfoRanger operates normally, these four
LEDs will be green.
