WBK20A Interface Card and Cable

The WBK20A is a PCMCIA/EPP Interface Card. Together, the card and associated cable provide a PC
with an EPP port by way of the computer’s PCMCIA slot.

The WBK20A typically has a data rate of 600 K to 1000 Kbytes/sec, or in terms of samples, 300 K to
500 K samples/sec [since 2 bytes is equal to 1 sample]. Although the WBK20A is capable of higher rates,
these are seldom realized because of such factors as: PC architecture, operating system, available
resources, and software implementation.

The earlier WBK20 and EPPCard/1 function the same as the WBK20A. The difference in
the devices is that the WBK20A uses cable CA-191-1, which has a locking cable connector;
whereas the earlier devices use a non-locking cable (CA-157-1). The two cable types cannot
be interchanged.

The WBK20A is not a “Hot-Swap” card. To ensure proper operation of the WBK20A card,
boot up the computer only after verifying that the WBK20A is inserted in the PC’s card slot.
Failure to do so may prevent the application software from recognizing the card as a
parallel port device.

Windows NT does not support the WBK20 or the WBK20A.

Testing the WBK20A Interface

N

During the installation of DaqBook Support, or WaveBook Support, from the data acquisition CD, a device
configuration utility (Daq* Configuration) is automatically installed in the Window’s Control Panel. The
utility checks and measures the PC’s port capabilities; and will check the interface of an installed WBK20A
that links a PC to a DaqBook or WaveBook.

Use the Daq* Configuration utility to test the WBK20A interf ace before running an application.

To test the WBK20A Interface you must:

•

Access the Daq* Configuration Utility

•

Add your DaqBook or WaveBook to the computer system.

•

Ensure the Device Settings are correct.

•

Run the “Resource Test.”

•

Check the test results.

A detailed description of these actions follows.

Troubleshooting

Symptom 1.

The WBK20A does not appear in the

Symptom Overview

If the Windows Device Manager fails to list the WBK20A, the installation was unsuccessful. The most
likely cause of an unsuccessful installation is the use of a wrong initialization file (inf).

For Windows 2000 and Windows 95/98/Me operating systems, an initialization file named Iotwbk20.inf
must be installed. Without this WBK20A-specific file, the installation will fail.

Note: In regard to WBK20A installations - in the Windows Device Manager, a yellow question mark and

a device labeled “unknown device” [or “other device”] is usually indicative of a failed installation.

Note: If you completed the installation using an old WBK floppy diskette, or a data acquisition CD

(p/n 1022-0601) that precedes version 2.1; then an outdated or a wrong inf file was selected.

Solution

To solve the problem of an incorrect WBK20A inf file, complete the following steps:

Windows Device Manager

1. Obtain a recent version of the file named: Iotwbk20.inf. You can acquire the file from your
data acquisition CD (version 2.1 or later), or you can download the WBK20A.exe file from an
FTP site. If you prefer to do the later, call for technical assistance.

.

2. In the Windows Device Manager, highlight the “unknown device,” or the “other device” entry.

3. Click the <Remove> button. This will remove the unknown device.

4. Physically remove the WBK20A from the computer. Note that you can do this while
Windows is running.

5. Reinsert the WBK20A into the computer.

6. Redo the installation process and, when prompted, select the correct inf file (Iotwbk20.inf).
You can obtain the file from the data acquisition CD, or from the file location where you
stored the downloaded inf file.

Reference Notes:

➣

Windows 2000 Users - Refer to the Windows 2000 Setup for WBK20A section
of this document, beginning on page 3.

➣

Windows95/98/Me Users - Refer to the Windows 95/98/Me Setup for WBK20A
section of this document, beginning on pa ge 7.

After completing the installation procedure, you should find that the WBK20A is listed in the
Windows Device Manager.

7. Make a note of the WBK20A’s LPT port.

8. Use the Daq* Configuration utility, located in the Windows Control Panel, to test the
WBK20A’s parallel port interface. Refer to previous sections of this document as needed.

are provided in the following Solution.

utility failed.

Solution

Test Results

If either of the Resource Tests failed, complete the following steps:

1. Make sure that the primary data acquisition device, e.g., DaqBook or WaveBook, has
adequate power, and that the power is turned on.

2. Check for obvious defects in the WBK20A cable.

3. Verify that good connections exist between the WBK20A and the primary data acquisition
device.

4. Make sure that you have installed the proper software support, i.e., DaqBook Support or
WaveBook Support from the data acquisition CD (p/n 1022-0601, rev 2.1 or later).

5. When running the Daq* Configuration utility, make sure that you have selected the parallel
port that is assigned to the WBK20A. In general, this parallel port is not LPT1, since LPT 1 is
typically the computer’s native parallel port.

If the only selection is LPT1, and LPT1 is not the port assigned to the
WBK20A, then the installation has failed and you need to revisit the previous
troubleshooting section entitled, Symptom 1.

Although Windows 2000 lets you select a port designated LPT1, LPT2, LPT3,
or LPT4, you must be sure to select the LPT port that agrees with the
WBK20A label in the Windows Device Manager.

22

10-12-01

WBK20A, PCMCIA/EPP Interface Card

If you have determined that the WBK20A has been installed successfully as an LPT device
but that the Daq*Configuration test does not wor k (after making sure that you have sel ected
the correct LPT port), then continue with step 6.

6. From the Windows Device Manager (in Control Panel ⇒System), see if there is an
exclamation point (!) in front of the WBK20A parallel port designation.

The exclamation point (!), if present, indicates that the parallel port was installed with a
resource conflict (I/O address or IRQ interrupt assignment).

If this is the case, complete the following:

•

Double-click on the WBK20A designation.

•

Select the Resources tab.

•

Uncheck the “use automatic settings” box.

•

Try different Basic Configuration options until you find one that shows no
resource conflicts.

An option is to try selecting either the interrupt request setting number or the
I/O address range and then clicking on the “Change Setting” button to
change the resources individually.

Note: Windows will give a message about whether the new configuration

conflicts with other devices or not.

7. After you have found an acceptable new resource setting, i.e., one that shows no conflicts,
restart the computer, then go to the Daq*Configuration utility and try the communication test
again.

You can find out what resources are currently free by going to the Windows Device
Manager and double-clicking on the Computer icon located at the top of the list. This
brings up a “View Resources” window that has an interrupt request (IRQ) option and
an Input/Output (I/O) resources option. Select each option in turn, and note which
IRQs and I/O addresses are not being used and are available.

8. If software support for other PCMCIA devices has been installed on the computer, but are not
currently being used, it is possible that there is a resource conflict that Windows is not
reporting. You can try to eliminate this conflict through the following process:

•

One at a time, insert each other PCMCIA device into your computer.

•

In the Device Manager, highlight the device, and click the <Remove> button to
remove the device from the list.

•

Repeat this process until you have removed all other PCMCIA devices from the
computer. This frees up the resources that these devices have been using and
eliminates any conflicts that were present.

•

If necessary, search for available resources and select them (see steps 6 and 7).
Restart the computer, go to the Daq*Configuration utility, then retry the
communication test.

Note: If the Resource Tests still fail after performing these steps, and there are no other devices to be

removed, it is likely that a successful WBK20A installation cannot be completed. If this is the
case, you will need to use the computer’s native parallel port. If the native parallel port is
available, and if you can run the port in either ECP or EPP mode, you will be able to obtain a
data transfer rate that approaches the WBK 20A throughput.
