Installing The CheetahModem Internal PCI
Checking Your Components
Unpack your CheetahModem and make sure you have the following items:
1. The CheetahModem.
2. A modular telephone cable to connect your CheetahModem to the telephone
line.
3. Communication software (included driver and manual)
When you open your package, make sure all of the above items are included and
not damaged. If you see that any components are damaged, please notify your
dealer immediately.
What Else You Need
To complete your data communication system, you will need the following items:
1. Other communication software, if needed.
2. An active telephone line and telephone set (if you need to use a
telephone with your modem).

7
Installing The CheetahModem
The following instructions explain how to install the CheetahModem into a PC
computer. If you will be installing the CheetahModem into a different computer,
refer to the manual that came with your computer or contact your computer dealer
for instructions.
1. Turn off the computer. No power must be applied to your computer when you
install the internal CheetahModem, or the computer could be damaged.
2. Make sure you can freely access the back of the personal computer. Remove
the computer cover.
3. Select any available PCI slot into which you can install the internal
CheetahModem.
4. Unscrew and remove the slot cover.
5. Hold the internal CheetahModem above the slot you have selected, and
carefully slide the CheetahModem into the slot, applying even pressure to both
ends of the CheetahModem. Stop inserting the CheetahModem when its
gold-plated edge connector is aligned and fully seated into the base of the
computer.
6. Use the screw that was holding the slot cover to secure the CheetahModem in
the slot.
7. Use the cover-mounting screws to secure the computer cover. This completes
the hardware installation of your CheetahModem.

8
Connecting To The Telephone Line
Use the following procedure to connect your CheetahModem to the telephone
line:
1. Locate an available RJ-11 modular jack telephone outlet.
2. Take one end of the modular cord supplied with the CheetahModem and plug
it into the LINE modular jack on the back of the CheetahModem.
3. Plug the other end of the modular cord into the modular jack on the wall outlet,
as you would any modular telephone.
Connecting To Your Telephone Set
Your CheetahModem also conveniently provides a second modular jack that lets
you connect your telephone to the same telephone line that the CheetahModem is
using. This lets you manually dial data calls or make voice calls when you are not
using your CheetahModem.Also if you do not have speakerphone and
microphone, handset of telephone set can function as an input/output device for
voice to verify the connection.
Use the following procedure to connect your telephone to your CheetahModem:
1. Connect the telephone's modular cord into the PHONE jack on the back of
your CheetahModem.
2. Lift your telephone's handset and listen for a dial tone.

9
Verifying Your Connection
Start a communication program and place the computer into terminal mode. Refer
to your computer manual to find out the appropriate command to do so.
Then use the following procedure to verify your installation:
1. Type
AT[Enter]
If your system is operating properly, your CheetahModem sends an
OK response to your screen and waits for your next command.
2. Use your communication software to prepare your computer to dial
a call. Then type
ATDx phone number[Enter]
where xis equal to Tfor touch-tone or Pfor pulse dialing. The
phone number is your telephone number.
For example, if your CheetahModem is connected to the telephone
line 555-2121 and touch-tone dialing is supported in your area, type
ATDT 5552121[Enter].
3. You should hear the busy signal and receive a BUSY response
because the CheetahModem is calling itself.
Connecting Microphone And Speaker
You could either use a handset connected to the CheetahModem, or connect
a microphone and a speaker for voice recording and playback.
NOTE:
Any commercially available microphone is usable.
For the speaker, any 8-ohm speaker rated around 1Watt can be driven
directly by the audio output. An amplifier is required if you need a
higher output volume.
1. Connect the microphone to the mini-phone jack marked MIC.
2. Connect the speaker to the mini-phone jack marked SPK.

Tips On Configuring Your Communications Software
Your CheetahModem uses the most up-to-date industryand commerciallypopular
standards to ensure functional compatibilitywith most communication software.
During initial set-up of the communication software, it will normally prompt you to
define the type of CheetahModem you are using. The following is a general
guideline for the device type you should choose.
NOTE:
The device type onlydefines the protocol bywhich your software will
communicate with your CheetahModem and will neither set nor limit
the speed that it will communicate with other devices.
1.For modem device type, choose 'Hayes V.32' or 'Hayes Compatible 2400
Baud' modem.
2.For the baud rate. Choose anyspeed between 38,400 to 115,200.Your
CheetahModem will automaticallyadjust to the best transmission speed
after successfullyconnecting with a remote CheetahModem.
3.Manycommunication software uses the modem response to control
program flow. Make sure that the software is set to recognize a CONNECT
28800 response. If this does not work, set the program to simplyrecognize
just the CONNECT response without anybaud rate information.
4.There are three flowcontrol mode: none, hardware (CTS/RTS) or software
(XON/XOFF). Set your software to use either hardware or software flow
control. If set to none, the communication software will not be able to detect
a buffer overflowand result in transmission errors.
5.For faxdevice type, choose 'TR29 Class 1'.
6.For faxspeed, choose 'automatic' or 'fastest speed'. Your CheetahModem
will automaticallyadjust to be best transmission speed after successfully
connecting with a remote faxmachine or another CheetahModem.
7.Make sure that you have correctlyset all the other parameters required by
the software to operate successfully. Refer to the manual that came with
your communication software for details.
Tips On Configuring SVD (Optional)
Add "-SMS=2" to the modem string in communication programs to enable
the SVD function. For complete SVD commands, please refer to the AT
command.

18
Executing Commands
If you will be using a communication software program to make data calls,
you will probablynot need to type commands, because your software
program will handle this for you. Similarly, you will probablynot see the
responses because your software program mayintercept them. However, if
you perform data activities directlywith your CheetahModem, you will find
the format for typing CheetahModem commands and fax/ modem response
helpful.
Using commands, you can have your CheetahModem perform a varietyof
activities, such as dialing or answering a data call or sending a fax. In order
to send commands to your CheetahModem, you must access the modem in
a terminalmode which is provided bymostcommunication software. To enter
a command line, type:
ATccpp[Enter]
ATmust precede everycommand line (except when you type the A/
command).
cc Refers to anyof the commands available, described in the following
sections.
pp Refers to anyparameters that is required bythe command.
If you make a mistake while typing a command, use the Backspace keyto
correct the error.
To make a command line easyto read, you can insert spaces, parentheses,
hyphens, and other punctuation in your command line. For example:
ATM3 DT9, 1(818)555-1234
Your CheetahModem ignores spacesand punctuation marks when executing
a command line, but these characters applyto the 40 characters limit.
Acommand line can contain up to 39 characters. If you want to type more
than 39 characters on a command line, type a regular command line (up to
39 characters long) and end it with a semicolon as the last character. When
you press Enter, your CheetahModem executes the commands and returns
to command mode, so you can type your next command line.
For your convenience, the last command line you execute remains stored in
the modem's memoryuntil you type a newcommand line and press the
Enter key. If you want to re-execute the last command, type
A/

19
The A/ command need not be prefixed bythe 'AT' characters or followed with
the [Enter] key.
If a command requires a parameter such as 0 and 1, the parameter is
identified as n in the left column and described in the right column.
IMPORTANT:
Each command, except for '+++' and 'A/', must be preceded by'AT' and
executed when you press the [Enter] key. To review the format used to
send CheetahModem commands, refer to Section of this manual.
