CCESS

The latest breakthrough in online communications

Until now, 33.6 Kbps was thought to be the practical limit for speed over standard phone lines. Now, x2 shatters that barrier, to bring you download speeds of up to 56 Kbps.

2

However, due to FCC rules which restrict power output of your service provider’s modems, current download speeds are limited to 53Kbps. This modem is easily upgradable to new features and enhancements as they become available.

An integrated end-to-end solution from the leader

U.S. Robotics is well positioned to bring you x2 technology. Our Sportster modems are the world's number one seller, and our Total

Control TM and Courier TM product lines are favored by many Internet service providers.

This widespread acceptance allows U.S.

Robotics to offer x2 technology to virtually anyone.

W ELCOME TO X 2 I NFORMATION A CCESS

Taking advantage of the modern telephone network

x2 technology uses the increasingly digital telephone network to bring you faster downloads, by eliminating the analog-to-digital conversion in the downstream path.

x2 takes advantage of the typical network configuration found when an analog subscriber connects to a digitally connected server.

Because it bypasses the analog-to-digital conversion in the downstream path, x2 can use nearly all of the available 64K network bandwidth. (Upstream data, typically less speed sensitive, travels at the standard V.34

rate.)

The result is a completely new kind of transmission technique. Based on “encoding” rather than “modulation,” it can give you download speeds that you never thought possible. What’s more, with standard V.42 bis compression, x2 can download at speeds up to a blistering 115.2 Kbps.

The new standard for online speed

U.S. Robotics has already submitted x2 to the

ITU-T standards committee for acceptance as the next online standard.

For more information on U.S. Robotics’ x2 technology, see our World Wide Web page at http://x2.usr.com

Speakerphone

With the addition of an inexpensive set of externally powered speakers, your new

Sportster Voice modem provides all the convenience of a full-duplex speakerphone.

Unlike many half-duplex speakerphones, your

Sportster allows you to converse normally without annoying echoes and distortion. Simply plug the speakers into the SPEAKER jack on the modem and you’re ready to go.

With Personal Voice Mail, you can record custom greetings, receive messages, and set up multiple voice “mailboxes”. You can even access your voice messages remotely.

Your modem will automatically detect incoming fax/voice/data calls and route them appropriately. The included fax-on-demand feature allows callers to select information from a list and have it automatically faxed to them.

Personal Voice Mail

Personal Voice Mail turns your modem into a full-featured messaging system. Enjoy the convenience of professional voice mail in your home or office for a fraction of the cost.

A Word about COM Ports and

IRQs

P ART I: S ECTION A: I NTERNAL M ODEM I NSTALLATION WITH W INDOWS 3.

X

Most computer accessories — a mouse, sound card, enhanced graphics card, scanner, etc. — require a special connection through which they can communicate with the computer. For an internal modem, it’scalled a communications (COM) port. Most computers have 1 or 2 COM ports but can have up to 4.

On an internal modem, the COM port is represented by the modem itself.

Each COM port uses an IRQ (interrupt request). An accessory uses an IRQ to get the attention of your computer’s CPU (central processing unit) so that the accessory can perform a task. The computer stops what it’s doing, depending on the priority of the request, to help the accessory perform its task. When two accessories share an IRQ, it’s like two people asking different questions in unison to a third person. Just as the person being asked the two questions cannot understand either request, a computer can lock up or otherwise fail to communicate properly with your modem when there is an IRQ conflict.

8


X

D

KEY POINT: Accessories cannot share

COM ports and should not share IRQs.

When accessories try to share settings, they will either not work properly or not work at all. This section of the manual will help you understand the COM/IRQ settings on your new Sportster.

NOTE: Some communications software programs require a particular setting for your modem. (RapidComm

Voice, which shipped with your modem, does not.) If you wish to use a program other than RapidComm Voice, now is a good time to read that software’s manual to determine what setting is required.

U.S. Robotics has set your Sportster to use

COM 2 and IRQ 3. This is the industry standard for modem settings. In most cases, these settings will work. In some instances, however, these settings are already being used by another accessory, such as a sound card or another COM port. We recommend that you run the ComTest program (on the

Connections CD) to determine what settings your modem should use.

How to Use ComTest to

Determine Your Modem’s

Settings

1. Insert your Connections CD into your CD-

ROM drive.

2. In the Windows Program Manager, select

Run from the File menu. Enter the file name as d:\comtest.exe. This starts ComTest,

X the program that determines which COM ports and IRQs are available for use by your modem.

3. The screen at the top of the next page appears when ComTest starts.

•

If there is a modem in your computer which you are replacing with your new

Sportster, you need to go to “Testing an

Installed Modem” on page 13 to determine which options to select so that

ComTest can detect what the older modem’s COM and IRQ settings are.

•

If a modem is not currently installed in your computer, choose the Recommend

settings for a new modem option.

Then click on the Next button.

If it’s not already selected, choose the

Internal Modem option.

“Testing is complete.” This screen will also tell you which COM and IRQ settings your present modem is using. These are the settings you want to use for your new Sportster. Write the settings down in the spaces provided on the first page of this manual.

Go to “What to Do with ComTest’s

Recommendation” on page 14.

Turn off your computer and remove your present modem.

•

If your present modem is using

COM2/IRQ3, go to “How to Insert the

Modem” on page 19.

•

If your present modem uses settings other than COM2/IRQ3, go to “How to Change the Factory Settings” on page 17.

What to Do with ComTest’s

Recommendation

If ComTest recommended COM1/IRQ4

You will have to change the factory settings on your modem.

NOTE: If your communications software requires a setting for your modem that ComTest does not recommend, there is a good chance that the setting is being used by another device in your system. To find out how to free that setting in your system, consult your computer manufacturer’s manual. If the communications software requires

COM2/IRQ3, go to “How to Insert the

Modem” on page 19. If the communications software requires different settings, go to “How to

Change the Factory Settings” on page

17.

Write “COM1” and “IRQ4” in the spaces provided on the first page of this manual. Go to

“How to Change the Factory Settings” on page 17.

If ComTest recommended COM2/IRQ3

You can insert the modem, as is, into your computer.

Write “COM2” and “IRQ3” in the spaces provided on the first page of this manual. Go to

“How to Insert the Modem” on page 19.

If ComTest recommended COM3/IRQ4 or

COM4/IRQ3

Do not use either of these settings.

this manual. You will have to change the factory settings on your modem. Go to

“How to Change the Factory Settings” on page 17.

While the COM port part of the setting is acceptable (ComTest only recommends

COM ports that are not being used), the

IRQ part of the setting is not acceptable.

When ComTest recommends either

COM3/IRQ4 or COM4/IRQ3, the IRQ in the setting is being used by another accessory. You could use the suggested

IRQ for the modem, but you run the risk that the modem and/or the other accessory sharing the IRQ might not work properly.

If you do not have a sound card, use

COM3/IRQ5. Write “COM3” and “IRQ5” in the spaces provided on the first page of

If you do have a sound card, use

COM2/IRQ3. To use this setting, you have to first disable your computer’s second serial port

(COM2). This is a pronged socket on the back of your computer.

Go to your computer manufacturer’s manual.

•

Find out which of the sockets on the back of your computer is the second serial port.

•

If you have something plugged into that port, find out if you can plug it in somewhere else. Any accessory plugged into that port after the port has been disabled will not work.

•

Find out how to disable the COM port.

14


X

•

Then return to this point in this manual to continue.

After disabling COM2, you can use the

COM2/IRQ3 setting.

Write “COM2” and “IRQ3” on the first page of this manual and go to “How to Insert the

Modem” on page 19.

If ComTest tells you that You do not have any available COM ports and/or IRQs

We recommend you disable COM1 or

COM2. When you disable one of these COM ports, you can use it and its default IRQ for your modem. Go to your computer manufacturer’s manual.

•

Find out which socket is COM1 and which is COM2.

•

If nothing is plugged into either port, you can disable either of the ports. Your computer manufacturer’s manual will tell you how to disable the COM port.

•

If one of the ports is being used by an accessory, choose the unused port. Note if the port is COM1 or COM2. This is the port you should disable for your modem.

•

If both ports are being used, you may be able to attach one of the accessories elsewhere so that you can disable that

COM port for use by your modem. The accessory will not work once its port is disabled.

If you’ve disabled COM1, you can now use the COM1/IRQ4 setting. Write this setting down on the first page of this manual. Go to

“How to Change the Factory Settings”.

If you’ve disabled COM2, you can now use the COM2/IRQ3 setting. Write this setting

X down on the first page of this manual. Go to

“How to Insert the Modem” on page 19.

How to Change the Factory

Settings

(NOTE: If ComTest recommended

COM2/IRQ3 for your modem, you can skip this section.)

1. Always touch an unpainted metal part of your computer (the back is usually unpainted) to discharge static electricity before handling the modem. Static can damage your modem.

2. Take the modem out of its plastic bag.

3. Find the COM port and IRQ shunts (small black plastic pieces) on your modem. They should be in roughly the area indicated in the following illustration.

4. To change the COM port and IRQ settings, you must move the shunts on the COM port and IRQ pins. To do this, lift the shunts off the pins.

16

TIP:


X

Grasp the shunts with a tweezers or needle-nosed pliers. DO NOT grasp too firmly, as you may crush the shunts. If a shunt seems stuck, gently rock it back and forth as you lift. Do not touch any other part of the modem or your computer with the tweezers/pliers.

5. Move the shunt to the new setting.

•

The COM port setting can involve one to three shunts. The four possible COM port settings are as follows:

0 1 SEL

0 1 SEL

COM 1

COM 3

0 1 SEL

COM 2

COM 4

0 1 SEL

•

Unlike most COM port settings, the

IRQ setting involves only one shunt.

Simply move the shunt to the pin labeled with the IRQ you want.

How to Insert the Modem

NOTE: Before installing your modem, write its serial number in the space provided on the first page of this manual. (You’ll find the serial number underneath the bar code on the white sticker on the modem and on the box the modem came in.) If you place a call to our technical support department, the technical support representative will ask you for the serial number. This will help him or her identify the type of modem you have.

17


X

1. Turn off your computer and unplug it from the electrical outlet.

2. Unplug any peripheral devices (printer, monitor, keyboard, mouse, etc.) from the computer.

3. Remove the screws from your computer’s cover and then remove the cover, as shown in the following diagrams. Your computer may differ in appearance from these diagrams, but the basic principle for removing the cover should be the same.

Refer to your computer manufacturer’s manual if you need further instructions.

TIP: Before you unplug anything, label the cords or make a sketch of how things are connected. This can be helpful when you plug things back in later.

CAUTION : To avoid risk of electric shock, make sure your computer and all peripheral devices are turned off and unplugged.

Find an empty ISA expansion slot that’s at least as long as the gold edge of your modem. ISA slots are black plastic grooves lined with silver. Unscrew and remove the expansion slot cover (the long narrow piece of metal that keeps dust from entering through the opening perpendicular to the slot). Be careful not to drop the screw into the computer.

5. Holding the modem at each corner, with the gold edge facing the slot, push the modem down as gently as possible until it snaps into the expansion slot. (NOTE: The drawings show horizontally aligned expansion slots.

Some computers have vertically aligned slots. The instructions apply to both styles.)

Sending Your First Fax

Using RapidComm Voice, you can send and receive faxes directly from your computer and eliminate the need for an expensive fax machine. Once you learn the basics of sending faxes, you can learn more involved fax functions (such as sending documents to groups of numbers at assigned times) and how to transfer data files.

Plug and Play Installation

With Windows 95, you should be able to simply plug your new modem into your computer, power up, and be ready to work.

The operating system does all the work of recognizing the modem for you. This section will walk you through this “Plug and Play” installation.

P ART I: S ECTION B: I NTERNAL M ODEM I NSTALLATION WITH W INDOWS 95

How to Prepare for Plug and

Play Installation

1. Touch an unpainted metal part of your computer (the back is usually unpainted) to discharge static electricity. Static can damage your modem.

2. Take the modem out of its plastic bag.

3. Find the COM port and IRQ shunts (small black plastic pieces) on your modem. They should be in roughly the area indicated in the illustration at the right.

4. When doing a “Plug and Play” installation, you need to take all the shunts off of the

COM and IRQ jumpers. Remove them, and then replace them so each is sitting on one jumper pin as shown in the illustration on the next page.

41


4. Once you have placed all the shunts on single jumper pins, you should be ready to insert the modem into your computer.

How to Insert the Modem

TIP: Grasp the shunts with a tweezers or a needle-nosed pliers. DO NOT grasp too firmly, as you may crush the shunts. If a shunt seems stuck, try gently rocking it back and forth as you lift. Do not touch any other part of your computer with the tweezers/pliers.

NOTE: Before installing your modem, write its serial number in the spaces provided on the first page of this manual. (You’ll find the serial number underneath the bar code on the white sticker on the modem and on the outside of the box the modem came in.)

If you ever need to call our technical support department, the technical support representative will ask you for the serial number. This will help him or her identify the type of modem you have.

42


1. Turn off your computer and unplug it from the electrical outlet.

2. Unplug any peripheral devices (printer, monitor, keyboard, mouse, etc.) from the computer.

3. Remove the screws from your computer’s cover and then remove the cover, as shown in the following diagrams. Your computer may differ in appearance from these diagrams, but the basic principle for removing the cover should be the same.

Refer to your computer manufacturer’s manual if you need further instructions.

TIP: Before you unplug anything, label the cords or make a sketch of how things are connected. This can be helpful when you plug things back in later.

CAUTION : To avoid risk of electric shock, make sure your computer and all peripheral devices are turned off and unplugged.

43

4.


Find an empty ISA expansion slot that’s at least as long as the gold edge of your modem. (ISA slots are black plastic grooves lined with silver.) Unscrew and remove the expansion slot cover (the long narrow piece of metal that keeps dust from entering through the opening perpendicular to the slot). Be careful not to drop the screw into the computer.

5. Holding the modem at each corner, with the gold edge facing the slot, push the modem down as gently as possible until it snaps into an expansion slot. (Note: The drawing shows horizontally aligned expansion slots.

Some computers have vertically aligned slots. The instructions apply to both styles.)

44


You’ll have to apply a little pressure to seat the modem properly. Sometimes a gentle back-and-forth motion helps fit the modem all the way into the slot. If you feel resistance, the modem may not be properly lined up with the slot. Do not force it into the slot. Remove the modem and try again.

6. Once the modem is in place, screw the modem firmly into place using the screw that you removed in step 4.

7. Put the computer’s cover back on and fasten it with the screws.

8. If you currently have a phone plugged into the wall jack you’re going to use for the modem, disconnect the phone’s cable from the jack.

9. Plug one end of the phone cable that came with the modem into the TELCO jack at the rear of the modem. Plug the other end of the cable into the wall jack. (If you want to use a telephone on the same line as the modem, plug the telephone’s cable into the modem’s PHONE jack.)

45



Most office phones are wired through digital lines. Be sure you know what type of line you have. The modem will be damaged if you use a digital phone line.

10. Plug the microphone into the MIC jack on the modem. Place the microphone where it will pick up your voice.

11. Plug the power cords, cables, and peripherals back into the computer and turn the computer on.

Every command except A/ and +++ must begin with the AT prefix and be entered by pressing <Enter>.

•

The maximum command length is 58 characters. The modem doesn’t count the AT prefix, carriage returns, or spaces.

Sets the required duration, in tenths of a second, of the remote modem’s carrier signal before recognition by the Sportster.

Sets the duration, in tenths of a second, that the modem waits to hang up after loss of carrier. This guard time allows the modem to distinguish between a line disturbance from a true disconnect (hang up) by the remote modem.

While we don’t recommend connecting the modem to a line with call waiting, if you have it, you may wish to adjust this setting upward to prevent the modem from misinterpreting the second call signal as a disconnect by the remote modem.

The 1.5K-byte non-ARQ buffer allows data transfer with Xmodem- and Ymodem-type file transfer protocols without using flow control.

The 128-byte option lets remote users with slower modems keep data you’re sending from scrolling off their screens. When remote users send your computer an XOFF (Ctrl-S) and you stop transmitting, the data in transit from your modem’s buffer doesn’t exceed the size of their screen.

This is also very helpful in situations when a remote modem/printer application is losing characters.

The Serial Interface

The serial interface is a standard developed by the Electronic Industries Association

(EIA). It defines the signals and voltages used when data is exchanged between a computer and a modem or serial printer.

The entire standard covers many more functions than are used in most data communications applications. Data is transmitted between the devices over a shielded serial cable with a 25-pin male (DB-25P) connector to the modem and a 25-pin, 9pin, 8-pin, or custom-built connector to the computer.

FCC regulations require the use of a shielded cable when connecting a modem to a computer to ensure minimal interference with radio and television.

Pin assignments are factory-set in the Sportster modem to match the standard DB-

25 assignments in the following table. DB-9 connectors for IBM/AT-compatible computers should be wired at the computer end of the cable as shown in the DB-9 column.
