Introduction
Thank you for purchasing the ActionTec DataLink V.90 PCMCIA fax/modem.
The DataLink V.90 gives the portable computer owner the mobility and connec-
tivity solution only a PC Card fax modem can deliver. Its small size and weight
are a perfect match for todays lightweight notebook computers.
The DataLink V.90 supports both the K56flex and ITU-T V.90 Standards for con-
nectivity to the largest number of Internet Service Providers. This dual mode modem
will automatically select the best possible protocol for your connection. Whether
it be faxing, e-mail, or connecting to the Internet, the DataLink V.90 gives the
mobile professional the connectivity solution needed for todays fast-paced envi-
ronment.
The DataLink V.90 has a programmable feature that enables you to change the
control codes that the modem uses. When new firmware (the commands that make
the modem work) becomes available, you simply download the update utility from
our website and reprogram the modem. This feature allows the modem to keep
pace with any changes that might be made in the future.
In February 1998, Study Group 16 of the ITU-T (International Telecommunica-
tions Union, Telecommunication Standardization) agreed on the technical speci-
fications for 56K modems (ITU-T V.90). As with any new standard, implementa-
tion will be an ongoing process. It may take some time for the entire industry to
switch from their proprietary methods to the new standard. The ability to change
your modems control code will allow you to keep pace with these changing con-
ditions.
Please visit ActionTecs website regularly for any new drivers available for your
modem. Under the Tech Support section you will find an area for 56K Modem
Upgrades. Our website address is: www.actiontec.com

Before You Begin
Please read the following tips carefully before attempting to
install your new modem.
For DOS/WINDOWS 3.1X INSTALLATION
 Most portable computers sold today include some form of Card and Socket
Services. This software enables the computers internal PCMCIA controller
to operate. If the computer beeps when the modem is inserted, the modem
should be configured and ready to use. If you do not have Card and Socket
Services, follow the procedure for installing the Point Enabler in this section.
 Windows 3.1 and Windows for Workgroups 3.11 do not require any special
drivers to communicate with the PC Card fax/modem if you are using your
systems Card and Socket Services software. You only need to install com-
munications software. If the version of the modem you purchased included
communications software, go to the section Installing and Configuring Soft-
ware and follow the installation instructions.
 If your computer does not have Card and Socket Services you will need to
install the Point Enabler. This program provides DOS with the necessary
drivers to interface with the modem. However, you will not be able to hot
swap the modem. The Point Enabler will have to be reinstalled any time you
insert or remove the modem. To install the Point Enabler in your system,
insert the installation diskette that came with your modem into the computers
floppy disk drive. Find the file pmxfm.exe and copy it to the root directory
of your default hard drive. The Point Enabler needs to be executed each time
you turn on your computer. This can be done by typing the following com-
mand line at the DOS C:> prompt:
pmxfm c=ni=nn <enter>
Where c specifies the COM Port number (from 1 to 4) and i specifies the
Interrupt used (from 1 to 15). Using COM 3 and IRQ 9 will work in most
systems. Once the pmxfm.exe driver has been loaded and is working cor-
rectly, you can add the statement to your autoexec.bat file.
Example: pmxfm c=3 i=9 <enter>
You may also need to modify your config.sys file to exclude an address range
when using the Point Enabler. The two examples below show the most effec-
tive ranges and will work with the majority of computers. Example A: shows
the most common exclusion range. Example B: may be the preferred setting

5
for certain notebooks. Try Example A: first and use Example B: if your re-
sults are not satisfactory. Add a line to your config.sys file as follows:
Example A: device=c:\dos\emm386.exe noems x=d000-dfff
Example B: device=c:\dos\emm386.exe noems x=c800-c8ff x=d000-dfff
Remember, the Point Enabler should not be used with any Card and Socket
Services software. It is meant to be used in a computer that does not have its
own PCMCIA Card and Socket Services software and is for a DOS/Win-
dows 3.1X environment only. It should not be used if you have a Cardbus
capable notebook or are running Windows 95/98 or Windows NT.
For WINDOWS 95/98 INSTALLATION
 Since a fax/modem is usually the first accessory purchased for a notebook
computer, it is a good idea to check that the computers PCMCIA controller
has been initialized and properly configured for Windows 95/98. Performing
this simple procedure will eliminate the major cause of installation difficul-
ties.
In Windows 95/98, go to: Start-Settings-Control Panel and double-click
the PC Card icon. A properly installed PCMCIA controller will show the
screen below.
If the New Hardware Found panel appears, your computers PCMCIA Ports
have not been configured. Follow the installation instructions on the screen.
You can also read your computers Users Guide for additional instructions on
configuring your PCMCIA ports for Windows 95/98.

6
For WINDOWS NT 4.00 INSTALLATION
 Check that your PCMCIA device setting is selected for boot and started. Go
to: Start-Settings-Control Panel and double-click the Devices icon. Scroll
down to the Pcmcia listing and highlight it by clicking once. If the PCMCIA
device is set correctly, you should see the screen below.
If the Pcmcia device is not set to boot and started, click once on the Startup
button. Select boot and click the OK button. Close the Devices window and
restart Windows NT before proceeding to the installation section
 Check that COM 2 is available for the modem to use. COM 2 is the preferred
COM Port for a Windows NT installation. It is recommended that you dis-
able COM2 through your System BIOS Setup routine (read your Computers
User Manual for instructions on how to invoke the BIOS Setup). Once inside
the BIOS Setup, look for a section called Integrated Peripherals. Locate the
entry for COM 2 or COM Port B and disable it. Save your settings before
exiting.

Installing the Modem
HARDWARE INSTALLATION
Your DataLink V.90 is housed in a Type II PCMCIA case. It will install in a Type
II or Type III 68 pin PCMCIA slot. PC Card slots are polarized and the modem
will install only in the correct orientation. Notebook computers usually have their
slots located on one side of the computer. To insert the modem, slide it gently into
the opening of the slot keeping it straight. Apply an even pressure until that last
one-half inch, then press firmly until the modem is seated completely into the
notebook. If the PCMCIA slots are recessed into the notebook, it may be difficult
to properly insert modem. Be sure to apply pressure until you feel the modem
click. This is especially true for new notebook computers. The illustration be-
low shows the modem being installed into a typical notebook.
Fig. 1: Installing the Modem
The modem comes with its own dedicated phone cable. This cable has a US stan-
dard RJ-11 connector on one end for the phone line and a special connector that
fits into the modem on the other end. Be careful not to push the computer against
an adjacent object when the cable is in place. This may bend the connector caus-
ing damage to the pins. Keep the area around the computer clear of large objects
so that you can move the notebook freely without hitting the cable or connector.

Installing and Configuring Software
INSTALLING COMMUNICATIONS SOFTWARE
If your modem came with a communications software package, it is strongly rec-
ommended that you use this software for your modem. Its default installation
parameters have been specially configured to work with this modem. The included
software supports both data and fax modes. To install this software on your com-
puter, follow these easy steps.
Step 1: Insert the diskette containing the communications program into your
computers floppy disk drive.
Step 2: If you are using Windows 95/98, go to My Computer and double-click
the floppy drive icon. Double-click the setup.exe file to install the soft-
ware in Windows 95/98. If you are using Windows 3.1X, go to File-Run
and type in the floppy drive letter followed by setup. This will load the
software for use by Windows 3.1X.
If you wish to use another software package, please be sure that it supports this
modem. Most software manufacturers have a listing of supported modems on their
websites or BBSs. Check these sites to see if this model is supported. If you are
unsure, or your brand of software supports only a few modems, try selecting Hayes
Compatible or Standard Modem. This may work in certain cases. Some soft-
ware programs allow manual input of parameters. For the users of these programs,
here is a listing of the data/fax command standards supported.
Data: TIA/EIA-602
Fax: TIA/EIA-578 for Class 1 Fax
Init String: AT&F&C1&D2W2
Note: Some programs must be configured to communicate with the mo-
dem on the same COM port and or IRQ setting used by the modem.

Troubleshooting
This section lists some common problems and offers suggestions for a solution.
Before attempting any troubleshooting, it is strongly recommended that you care-
fully follow the pre-installation procedures outlined in the Before You Begin sec-
tion. These steps have been thoughtfully chosen to help minimize difficulties dur-
ing the installation of the modem in both Windows 95/98 and Windows NT 4.00.
If you have installed the modem without performing any of the pre-installation
steps, eject the modem from the computer and remove the driver from the Mo-
dems panel. Go to Start-Settings-Control Panel and double-click the Modems
icon. Highlight the modem by clicking once and then click the Remove button.
Restart Windows 95/98 and follow the pre-installation suggestions listed in the
Before You Begin section before attempting a reinstallation. If you have rein-
stalled the modem but it is still not functioning or Windows does not detect it,
follow the suggestions listed below for your particular symptom. These trouble-
shooting procedures will correct the majority of installation problems that might
be encountered when installing the modem.
Case 1: Resetting the PCMCIA Controller (Modem Is Not Detected).
Resetting the PCMCIA Socket controller corrects the vast majority of non-
installation difficulties and should be the first step chosen when trying to
remedy a situation where the modem is not detected. Before attempting
this procedure, uninstall the modem using the procedure outlined in the
previous paragraph.
Go to Start-Settings-Control Panel and double-click the System icon.
Select the Device Manager tab to display the device tree. In the device
tree, double-click the PCMCIA Socket icon to expand the socket tree.
Highlight the listed socket device by clicking once on the icon, then click
the Remove button. Exit Device Manager and restart Windows. On startup,
Windows should detect new hardware for the PCMCIA Socket that was
previously removed (If Windows does not detect new hardware, go to
Start-Settings-Control Panel and double-click the PC Card icon). At
the PCMCIA installation screens, choose No, No, and then Finish. The
PCMCIA controller in your system is now reset. Go to Start-Settings-
Control Panel and double-click the PC Card icon. The screen should
say socket 1 & socket 2 empty. Try reinstalling the modem again using
the steps in the Installing The Modem section.
Case 2: Correcting a Cannot Open COM Port Error (Disabling a COM Port)
When Windows displays a Cannot Open COM Port Error, it means that
there are no COM Ports available for the modem to use. To correct this
condition, you must disable any unused COM Ports listed in Windows.

20
COM Port 1 (COM 1) is usually required by the system and should not be
removed. Go to Start-Settings-Control Panel. Double-click on the Sys-
tem icon, and select the Device Manager tab. From the device tree, double-
click the Ports [COM & LPT] icon to expand the Ports tree. COM 1
should be listed. If COM 2,COM 3, or COM 4 are listed, disable them by
clicking once to highlight each port and then click the Properties button.
At the Properties screen, Uncheck Original Configuration, Current (Win-
dows 95a) or check Disable In This Hardware Profile (Windows 95 OSR2).
If there is a message screen, choose yes and click the OK button. If the
COM Port is properly disabled, there will be a red X over the COM Port
icon.
Case 3: Modem is installed as a Standard Modem or some other modem. Not as a
DataLink V.90 Modem. (Windows will not use the driver disk)
When you insert your modem into the computer, Windows 95 detects it as
either new hardware or as hardware that has already been installed at one
time. Under rare circumstances, Windows 95 will see your modem and
identify it as new hardware, but will not use the installation files that you
give it. Instead, it uses some other .inf file, usually one from previously
installed hardware. As a result, your modem does not work with Windows
95 programs like Dial Up Networking (but will work with programs that
access COM Ports). Correcting this condition requires that you know the
version of Windows 95 that you are using. To find the version of Windows
95 on your computer, go to Start-Settings-Control Panel. Double-click
on the System icon. If the version of Windows 95 is 4.00.950 or 4.00.950A,
use the Windows 95a procedure below. If the version of Windows 95 reads
4.00.950B, see the procedure for Windows 95 OSR2. Read these instruc-
tions first before attempting anything. If you feel uncomfortable with re-
naming files, please ask the assistance of someone who is knowledgable
with Windows files and Windows file extensions.
Windows 95a
Eject the modem from the computer and go to Start-Settings-Control
Panel. Double-click the Modems icon. Highlight the modem by clicking
once and then click the Remove button. Close the control panel and return
to the desktop screen. Do not reboot or restart the system. Now go to
Start-Programs and select MS-DOS Prompt. At the c:> prompt, type in
the following commands in the order listed (Note: if you have renamed
your Windows Directory from C:\Windows, substitute the new name for
Windows in the commands that follow.):
cd c:\windows\inf <enter>
rename *.inf *.bak <enter>
exit <enter>
