Phone Line Requirements

The phone line required by the Viking Components fax/modem is an analog RJ-

11. This is a standard residential phone line.

Warning: Do not use a PBX or digital phone line. These phone lines may
damage the Viking Components External fax/modem or phone equipment.

PBX or digital lines are used by many businesses for their phone systems. To
determine if the line you wish to use is analog,look on the jack or the phone. If it
says “analog,”“computer,”“data” or “modem,” it is an analog line. If you are in an
office and the phone is not labeled, check with the phone system administrator.
If you are in a hotel, call the hotel operator for more information.

Communications Software requirements

Please refer to the communication software “User Guide” for additional system
requirements for installing the communication software.

3 Installation

This chapter contains instructions on installing your Viking 56K External
fax/modem.

Hardware Installation

1. Turn off your computer and any attached devices, such as printers or external
drives.

2. Locate the serial port on the back of your computer and connect it with the ser­ial cable on the back of the external modem.

Windows Based Systems: It may be marked COM, SERIAL, MODEM or RS-232.

Do not select AUX, GAME or PARALLEL port. If you are not familiar with the

location of these ports, your computer uses icons to mark its ports or there are no
markings on any of the ports, please refer to your systems “Owner’s Guide”for
detailed instructions. The Viking external modem comes standard with a 9-pin
connector on its serial cable to correspond with the majority of today’s systems.
If you computer has a 25-pin serial port, you will need to purchase a 9-pin male to
25-pin to female adapter.

Mac Based Systems: Locate the external modem port on the back of your

machine. Plug the corresponding connector on the serial cable into this port.

Hardware Installation (Continued)

3.Plug the AC power adapter into a standard wall outlet. Also plug one end of the
phone cord into a wall phone jack.

Warning:The phone jack you use must be for an analog phone line. If
you are in a office building, it may use digital phone lines. If you are not sure
of the type of phone lines your office building has, contact your phone sys­tem administrator.

4. Rest the modem on its side. Locate the two phone cord jacks toward the cen­ter of the bottom panel. These jacks are interchangeable when connecting the
modem to a wall jack and a phone. Plug the available end of a phone cord into
one of the jacks and the other end to the phone jack located on the wall. If you
wish to use your modem and phone through the same wall phone jack, plug the
cord from your phone into the remaining jack on the modem.

Note: You can not use the phone and the modem at the same time if they share
the same phone line.

Using Data and Fax Communication Software

Usually, most communication software installation programs will automatically
detect your Viking fax/modem and preform the appropriate configurations. In
some cases,you may find it necessary to configure the software so it can send the
appropriate commands to the fax/modem.

Although most applications have many different modems already programmed
into the software application, sometimes you may not be able to find the exact
match for your modem. For the best compatibility, select a Hayes Compatible
modem from the list of modems. If this is unavailable,change the modem initial­ization string. To change the string,please see the section below.

Changing the modem Initialization String

If you can not find a matching modem listed, you can modify the modem initial­ization string. Please refer to the data and communication software “User’s Guide”
for details on making this change. The best initialization string to use is:

5 Troubleshooting

This chapter will cover some solutions to some common problems you may expe­rience when installing your Viking PC Card modem. Some solutions may not
apply to your operating system or may not be listed. If your problem is not
answered in the following sections, please proceed to page 39, on contacting
Viking for support. For software problems, please refer to the communication
software “User Guide” for solutions.

General

Problem

Modem does not respond, modem
communication error or modem
not found.

Solution

•

Did you select the correct modem type? If the Viking

modem is not listed, try a Hayes compatible modem.

•

Is the COM/Serial cable completely plugged into its port

and are all of the connections secure?

•

Check your computer’s BIOS setup. You may need to dis-

able a built-in COM port to prevent conflict.

•

Is your operating system set to the correct Com port and
IRQ? Please refer to chapter 4, “Technical Notes”for
detailed information.

•

Did you select the correct COM port? Usually, the com­munication software selects the COM port automatically
during installation. Be sure that the COM port setting in
your communication software matches the setting used in
your “Card and Socket Services” software.

•

Check your computer for conflicting COM port settings.

•

Does your system recognize your Viking external

modem?

•

If the modem stop after the computer enters power-sav­ing mode, disabling this feature is recommended.

Is the telephone number correct?

•

Did you enter a “1” before the area code when dialing

long distance?

•

Are you required to enter a prefix, such as a “9” in your

settings.

•

Is the other line busy or not answering? Make sure it is

available before calling.

•

Did you select the correct fax class? Check your software,

INDUSTRY CANADA (IC) NOTICE:

“NOTICE: The Industry Canada (IC) label identifies certified equipment. This certification
means that the equipment meets certain telecommunications network protective, oper­ational and safety requirements as prescribed in the appropriate Terminal Equipment
Technical Requirements documents(s). The department does not guarantee the equip­ment will operate to the user’s satisfaction.

Before installing this equipment,users should ensure that it is permissible to be con­nected to the facilities of the local telecommunications company. The equipment must
also be installed using an acceptable method of connection. The customer should be
aware that compliance with the above conditions may not prevent degradation of ser­vice in some situations.

Repairs to certified equipment should be coordinated by a representative designat­ed by the supplier. Any repairs or alterations made by a user to this equipment, or equip­ment malfunctions, may give the telephone communications company cause to request
the user to disconnect the equipment.

Users should ensure for their own protection,that the electrical ground connections
of the power utility, telephone lines and internal metallic water pipe system, if present,
are connected together. This precaution may be particularly important in rural areas.

Caution: Users should not attempt to make such connections themselves, but
should contact the appropriate electric inspection authority, or electrician, as appropri­ate.”

“NOTICE: The Ringer Equivalence Number (REN) assigned to each terminal device
provides an indication of the maximum number of terminals allowed to be connected to
a telephone interface. The termination on an interface may consist of any combination
of devices subject only to the requirement that the sum of the Ringer Equivalence
Numbers of all the device does not exceed 5.”

REN: 1.0B

PART 68 REQUIREMENTS:

This equipment complies with Part 68 of the FCC Rules. On this equipment there is
a label that contains, among other information, the FCC Registration Number and Ringer

An FCC compliant telephone cord and modular plug are provided with this equip­ment. This equipment is designed to be connected to the telephone network or premis­es wiring using a compatible modular jack which is Part 68 compliant. See installation
instructions for details.

The REN is useful to determine the quantity of devices you may connect to your tele­phone line and still have all those devices ring when your telephone number is called. In
most,but not all areas, the sum of all the REN’s of all devices connected to one line should
not exceed five (5.0). To be certain of the number of devices you may connect to your
line, as determined by the REN, you should contact your local telephone company to
determine the maximum REN for your calling area.

If your telephone equipment causes harm to the telephone network,the telephone
company may discontinue your service temporarily. If possible, they will notify you in
advance. But if advance notice is not practical, you will be notified as soon as possible.
You will be informed of your right to file a complaint with the FCC.
