When selecting a basic configuration from the Setting Based on
list, pay attention to the Conflicting device list information.
Try to select a configuration that displays No Conflicts. If resource
conflicts can be resolved by switching to one of the predefined
basic configurations, then skip down to step 5.
- To change or modify any of the system resources showing a conflict:
- Click on the Resource name
- Then click the Change Setting button
- An Edit Resource window will open up. Notice that I/O address
resources for basic configurations 0 and 1 are NOT ALLOWED
to be changed.
- Inside the Edit Resources window, click on the up/down arrows
to the right of the resource value. This scrolls you through
all of the allowable resources for the SPP-100. Pay attention
to the Conflict Information at the bottom of the window. Select
a resource value that reports No devices are conflicting.
- Click OK to save your changes or Cancel to abort. Repeat
the above steps to resolve all resource conflicts. Once satisfied
with the settings make a note of the new settings and click
the OK button to accept. Clicking the Cancel button does not
save your changes.
- Windows 95/98/Me enumerates the SPP-100 to the first available
LPT port number. Use this Logical LPT Port name to access the
SPP-100 parallel port through your software applications. This
name is required by a Windows 95/98/Me application when accessing
a particular port.
- The SPP-100 will automatically be reconfigured to the new resources
specified. Any time a SPP-100 is inserted Windows 95/98/Me will
attempt to configure the card at these resource settings. Click
the Use Automatic Settings to reset the SPP-100 for automatic
configuration.
Q3. My SPP-100 appears to have installed
correctly on my laptop, but it can't communicate with my parallel
devices. What can I do?
A. Quatech has recently released a new revision of the SPP-100
(rev. F), that is compatible with both 3.3V and 5V systems. However,
the card it replaced, rev. E3, is a 5V PCMCIA card and is known
to be incompatible with some new laptops that do not provide enough
power for the card, including those listed below. If you experience
this problem we suggest you contact your laptop manufacturer to
determine whether there is a voltage incompatibility with rev. E3.
Here is a list of laptops currently known that provide only 3.3V
power in the PCMCIA slot (rendering them incompatible with revisions
of the SPP-100 prior to, and including, E3):
- Acer Travelmate 2200
- Compaq Presario X6000 series
- Compaq Mobile Workstation NW824
- Compaq NX9020
- Dell Inspiron 6000
-
Fujitsu Lifebook N-Series
-
HP ze4900
- HP DV1000
- Panasonic Toughbook CF-51 series
- Panasonic CF-72 series
- Panasonic CF-73 series
- Panasonic CF-M33
- Sony Vaio V505
- Toshiba Libretto 100
Beginning with rev. F, which is now available, the SPP-100 is compatible
with both 3.3V and 5V systems.
Q4. I have a Dell Inspiron or other laptop that does not
have an onboard parallel port and my SPP-100 is installed correctly
under Windows XP Home/Pro, but I cannot communicate with my parallel
device. What can I do?
A. You need to change the resources allocated to the SPP-100
to remedy any system conflicts. Follow the steps below:
- From within Device Manager, expand the "Ports (COM &
LPT) tree
- Right mouse-click on "Quatech SPP-100" and select
"properties"
- Select the "Resources" tab
- Uncheck the "Use automatic setting" box
- Using the drop-down box try "Basic configuration 0001"
or select any configuration that displays "No Conflicts"
in the "Conflicts window." Be certain to avoid the 03F8
address, as it is known to cause system conflicts.
Q5. How do I configure the Sentinel System
Driver to work with Quatech's SPP-100 Parallel PCMCIA card?
A. Follow the directions below to configure the Sentinel

Q7. Can I use my SPP-100 on a handheld computer?
A. Quatech provides Windows CE drivers for the SPP-100.
As Windows CE is implemented differently in different systems, the
Quatech standard driver contains support files for only the most
popular CE-based handheld devices. Click
here for a list of supported devices. If the standard driver
does not work with your equipment, please submit our Technical
Support Request form to get the appropriate files for your system.
Quatech can also provide specialized drivers for embedded systems
implemented with Windows CE. OEMs interested in this service should
contact us with their specific requirements.
We also provide a free driver for the HP-Palmtop. It can be downloaded
here.
In addition, Quatech products will configure with Intel compatible
processors (80x86 based) using the client driver. You should be
able to use any card we manufacture as long as you are using an
80x86 based processor. The enabler that we supply for use when the
client driver cannot be used only works with Intel 82365SL or compatible
socket controller chips. These are our only restrictive requirements.
Q8. Your Windows CE drivers for my Parallel
PCMCIA card do not work with my handheld computer. What is wrong?
A. As Windows CE is implemented differently in different
systems, the Quatech standard driver contains support files for
only the most popular CE-based handheld devices. Click
here for a list of supported devices. If the standard driver
does not work with your equipment, please submit our Technical
Support Request form to get the appropriate files for your system.
Q9. Should I disable the Toshiba laptop
built-in infrared ports in the system BIOS before installing my
PCMCIA card?
A. Yes. Experience has shown that these infrared ports can
interfere with the proper installation of Quatech PCMCIA cards.
Once the installation is complete, these ports can be enabled again
without further problems
Q10. Under which OS is my parallel PCMCIA
card supported?
A. View the latest OS
support matrix for Parallel PCMCIA cards.
Q11. Why can't I configure my SPP-100 for
EPP mode under Linux/Windows CE?
A. EPP mode is not supported under these operating systems.
Q12. How do I install my Parallel PCMCIA
card under Windows 2000/XP?
A.
- Install your hardware according to the instructions in your
user's manual. Boot your machine. (You needn't shutdown the machine
to insert a PCMCIA card)
- The "Welcome to the Found New Hardware Wizard" window will open.
- Click "Next" to continue.
- Follow the on-screen instructions. When prompted, point Windows
to the location in which the Quatech drivers are stored-typically
on the Quatech COM CD, or the folder on your hard drive to which
you downloaded the drivers.
Q13. What does it mean to have an unregistered
Windows XP driver? Why do I get a warning screen when I install
some Quatech drivers?
A. Microsoft has implemented a new driver signing program.
This program verifies that the driver will not cause problems on
the system. Although driver signing isn't a complete indication
that a driver is safe or bug-free, it's certainly reasonable to
assume that signed drivers are generally safer for overall system
health than unsigned drivers. In addition, driver signing ensures
against a Trojan horse or virus application being introduced into
a driver, or having the driver replaced with other code.
However, just because a driver is unsigned DOES NOT mean that it
will not function properly in your system. An "unregistered" driver
is one that has not been officially tested and certified by Microsoft.
Unlike previous versions of Windows, Windows XP warns users every
time they try to install a driver that Microsoft has not certified.
Quatech thoroughly tests all drivers before releasing them to our
customers. The Microsoft XP warning has nothing to do with the quality
of our driver or its ability to function properly in your system.
XP driver development is an ongoing process. We are in the process
of submitting all Quatech Windows XP drivers for review by Microsoft,
and we fully expect to receive certification for most products in
the coming months. However, every time we update a driver it must
be re-certified. Until this certification process is complete, the
updated driver will remain unsigned. Because we want to provide
the best possible service for our customers, we release our XP drivers
prior to receiving Microsoft certification--this gets it into your
hands faster! However, we will always continue to make the most
recent signed driver available even if there are more recent unsigned
updates.
When you see this warning during an installation of a Quatech's
Windows XP driver, simply tell Windows that you want to install
the driver anyway, and continue with the standard installation process.
Q14. How do I disable the Windows XP Driver
Signing check?
A. To disable Windows XP driver signing warnings, follow
the steps below:
- Double click on the System icon in Control Panel.
- Left click on the Hardware tab.
- Left click on the Driver
Signing button. (click here for a screen cap of the Driver
Signing Options Window)
- Choose the Ignore option. Click on O.K. and then Apply and O.K.
- Windows will not warn anymore about driver signing.
Q15. Will my Quatech Parallel PCMCIA card
work under Windows 95/98/Me/NT/2000/XP that is controlled by a third
party PCMCIA card services (Softex, Card Wizard, etc.)?
A. Quatech developed its drivers to work directly with the
ones found on the Windows operating systems. Enabling these original
Windows's drivers will provide quick and easy installation of all
Quatech's PCMCIA cards. We cannot predict how or if our cards will
function when used with another company's card services.
Q16. Why does Windows 95 change the basic
configuration of the SPP-100 to basic configuration 0002 when I
choose basic configuration 0003 for EPP mode?
A. For some reason we cannot explain, Windows 95 does this.
We have tried to correct this problem, but Win95 refuses to do anything
differently. We believe that it is some inherent problem with Win
95, but we cannot fully prove this. When configuration 0003 is initially
chosen you will see a memory allocation range for the configuration
where the I/O range and IRQ usually are. Click OK and then restart
the system, as Win95 wants to do. Allow the machine to boot normally
and check the configuration again. You should see that the configuration
has been changed to basic configuration 0002. A valid I/O range
and IRQ have been chosen for the card. Although the card does not
appear to be in EPP mode, the card is ready to function as a standard
EPP port. If you find that the card does not function properly,
please contact us by submitting the Technical
Support Request Form.
Q17. Why does Windows 95 configure the
SPP-100, but not assign a LPT number to the port?
A. Windows 95 handles enumerating PCMCIA COM ports (i.e.
PCMCIA modems) much better than the case of parallel ports. After
initial installation or any configuration changes of the SPP-100,
Windows 95 may fail to assign a logical LPT number to the parallel
port. The solution to this problem is to shut down and restart Windows
95 with the SPP-100 installed.
Q18. Where can I find help with using my
Parallel PCMCIA card under OS/2?
A. Though OS/2 is becoming increasingly less popular, Quatech
knows that there are many dedicated users out there, and we are
committed to continued support of OS/2. See our OS/2
tip sheet for answers to common questions about installation,
un-installation, configuration, and troubleshooting.
Q19. Why are Quatech PCMCIA cards no longer
supported under DOS?
A. Quatech DOS support for PCMCIA cards was built to work
with Card and Socket Services from System Soft. Newer laptops do
not use this software, and System Soft is no longer supporting it.
If you have a computer with Card and Socket Services installed you
should be able to use Quatech's cards under DOS. However, as there
is no longer any support for the program, we can no longer continue
to support our cards under DOS.
Q20. I am using a computer running Card
and Socket Services. Can I still get the Quatech DOS drivers for
my PCMCIA cards?
A. Yes. Quatech DOS drivers for Communication PCMCIA cards
can be found on the Support for Discontinued
Product page. These drivers are for use at your own risk, and
our technical support team cannot provide any help with installation,
configuration, or troubleshooting. However, our tip sheet "PCMCIA
for DOS" may provide some useful suggestions.
Q21. Where can I get HP Palmtop drivers
for my SPP-100?
A. HP Palmtop Drivers can be downloaded here.
Q22. How do I completely remove all support
for the SPP-100 from Windows 95/98/Me/2000/XP?
A. Removing support for the SPP-100 out of Windows is a
two step process:
- Clear the Registry: Windows maintains a registry of all
known hardware installed in your computer. Use Windows Device
Manager and "Remove" the SPP-100 adapter from the system. This
action clears the registry of all entries and configurations for
the SPP-100.
- Remove the SPP-100 INF File: The installation process
of the SPP-100 used an "INF" configuration file to install support
for the SPP-100 into the Windows registry. A copy of the SPP-100.INF
file from the installation disk was placed in the \WINDOWS\INF
directory during the SPP-100 installation. However, the file has
been renamed to OEMxx.INF (OEM1.INF, OEM2.INF, etc.). Carefully
compare the SPP-100.INF file on the installation disk with each
of the OEMxx.INF files and find the match. Then make a backup
of the OEMxx.INF file containing the SPP-100 configuration information
and delete the file from the \WINDOWS\INF directory.
Note: The subdirectory \WINDOWS\INF has by default
the hidden file attribute applied to it. To view hidden files
and directories, start the Windows Explorer and from the menu
select View|Options. An options dialog box will open. Click
on Show all files and then click OK to accept the
change. Once changes inside the INF directory have been completed,
you may want to change Explorers view option back to Hide files
of these types. By hiding many of the system files in Explorer,
the chances of accidentally deleting or modifying these key files
is reduced.
Q23. Can I use the Quatech SPP-100 with
KEYLOK?
A. No. According to KEYLOK tech support, their dongle is
NOT compatible with the SPP-100 or any other pcmcia parallel card.
Q24. How do I configure the SPP-100 for
use with the Hasp/Aladdin dongle?
A. The Hasp/Aladdin dongle has a configuration utility that
needs to be configured for the SPP-100 base address.
To do this, first set the SPP-100 port to LPT1 with a manual I/O
address range of 478 - 47F (automatic setting chooses FFF8 - FFFF).
Then use the HASP Hinstall.exe application to install the driver
(this is the command line version of HDD32.exe). Use the command
line switch -lpt1=478 when running Hinstall. The dongle should then
be visible.
1. Set the SPP-100 to be LPT1 (if it is not already). This is done in Device Manager under Ports (COM & LPT), double-click on the SPP-100 and then select the Port Settings tab.
2. Click on the Resources tab, and set the SPP-100 to a manual I/O address range of 0478-047F.
3. Press OK and exit out of Device Manager.
4. Download the HASP portion of the driver from Aladdin's website here: http://aladdin.com/support/hasp/hasp4/enduser.asp
5. Under HASP Device Driver Downloads, you want to click on the first link in that row for the HASP Device Driver GUI Installation. Download this file to your desktop.
6. Extract the file that you downloaded.
7. Open the folder that was created during the extraction process and double-click on the file hdd32.exe. This will install the HASP portion of the driver.
8. After driver installation, reboot. You are now ready to use your Aladdin dongle.
Q25. Why can't my SPP-100 communicate with
Canon Multipass devices?
A. Canon multipass devices such as printers and scanners
require a parallel port functioning in ECP mode. The SPP-100 does
not support ECP mode (It is an EPP parallel port card.)
Q26. What does PCMCIA stand for?
A. Personal Computer Memory Card International Association
This group is "an international standards body and trade association
with over 200 member companies that was founded in 1989 to establish
standards for Integrated Circuit cards and to promote interchangeability
among mobile computers where ruggedness, low power, and small size
were critical." (Excerpted from the pcmcia.org site). Its main job
is to oversee the continued development of portable peripherals
built on the PCMCIA form factor.
For more information on PCMCIA go to:
www.pcmcia.org.
Q27. How do I get my D2K dongle to work with my SPP-100?
A. The latest DK2 driver installation (v6.08.0.154) can be found here, it includes support for Windows XP :
http://www.deskey.co.uk/deskey_downloads.php. We would recommend using LPT 2 address of 0278.
Depending on how the PCMCIA device implements its driver the DESkey drivers may not be able to find the LPT port, you can hard code the address the DK2 to be searched by adding it as a DWORD registry value named 'LPTPort' in 'HKLM\System\CurrentControlSet\Services\dk2drv\Parameters'.
Q28. How do I get my Metrowerks code warrior / OCDemon Wiggler working with my SPP-100?
A. Here are instructions on the commands needed to get the SPP-100 to work with the Metrowerks Code Warrior/OCDemon Wiggler Jtag Programmer working:
Metrowerks uses a Command Converter Server which is part of the CodeWarrior software. The CCS usually appears in the icon window next to the time once the OCDemon Wiggler is tried. Double click on the icon for the CCS. This will open a window that looks and acts like a command prompt. The following commands need to be entered.
- delete all
- config cc lpt:0xFFF0 (where 0xFFF0 is the address of the parallel port)
- save cc
- config save
These commands should point the CCS to the correct parallel port, save the configuration for later use, and allow use.
Q29. Can I use the Quatech SPP-100 with my Keylok or Husqvarna Viking Dongle?
A. Both manufacturer's said that their dongles will not work with a USB or Parallel PCMCIA parallel port.
Q30.Will my Activator dongle work with the SPP-100?
A. The Activator dongle does not work with the SPP-100.
Q31. When installing a product, I get an error message stating "The System Cannot Find the File Specified." How can I fix this?
A. Windows 2000/XP has a bug that it cannot properly detect new hardware by *.inf files, if the RunOnce registry key is missing.
This key is often used by installers to execute post-reboot programs, but sometimes they accidentally delete this key.
Go to Start » Run and enter "regedit"
Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion
With CurrentVersion Highlighted, go to the Edit menu and select New » Key
Name the key RunOnce - Leave everything else about the key alone.
The RunOnce key should now exist underneath the CurrentVersion key.
Reboot your PC.
Once the key exists, Windows 2000/XP stops redetecting the Hardware
Q32. What are the output signal levels at the DB25 connector when plugged into a laptop capable or providing either 3.3V or 5V to the PCMCIA card?
A. The SPP-100 has an on-board 5V DC-DC converter, so output voltages will always be 5V TTL, even when plugged into a 3.3V slot.
