Measurement Computing WaveBook rev.3.0 - Manual (Page 158)

9-2 Troubleshooting, 6-21-99 WaveBook User’s Manual
Overview
This disk set contains a Driver for Windows NT/95/98 for the WaveBook product line. This disk set
includes the following:
• WaveBook Windows NT driver
• WaveBook Windows 95/98 driver
•
DaqX.DLL
(Enhanced API) for the WaveBook
•
WbkComp.DLL
(Standard API) for the WaveBook
• Microsoft C Standard API support
• Microsoft C Enhanced API support
• Microsoft VB Standard API support
• Microsoft VB Enhanced API support
• Borland Delphi Standard API support
• Borland Delphi Enhanced API support
• Daq* Configuration Control Panel Applet.
Upon installation, the user needs to run the Daq* Configuration Control Panel applet. Using this applet, the
WaveBook should be configured on the appropriate LPT port. This must be performed in order for the
application to access the WaveBook through the Windows NT or Windows 95/98 driver.
Driver Support
WaveBook applications can be written to either the Standard API or to the new Enhanced API. The
Standard API has the same format (only written to 32-bit mode) as the Windows 3.X version of the driver.
These functions have the
wbk...
prefix. The Enhanced API is a new format which can be generically used
with the WaveBook, DaqBook, DaqBoard, Daq PC Card and TempBook product lines. These functions
share the
daq...
prefix.
If starting with an existing WaveBook application written to Windows 3.X then the quickest port would be
to the Standard API. If writing a new application it is most desirable to write to the Enhanced API due to its
slightly improved performance and its enhanced feature set.
The API support examples can be found in the installed directory
\LANGS\WAVEBOOK
.
Connection Problems
If communications cannot be established with the WaveBook or trying to connect causes the system to hang
or crash, try the following. For detailed troubleshooting instruction for Windows 95/98, see section
Windows 95/98 Problems below.
• Check power LED on the unit make sure that it is on. If not on, check power connection for proper
connection to the WaveBook and the power source.
• Check to make sure that the LPT cable is firmly attached to the appropriate LPT port on the computer
and that the other end is firmly attached to the "TO COMPUTER" port on the WaveBook.
• Check that the desired LPT port is properly configured and the base address and interrupt are
recognized by the operating system.
• Check the BIOS settings for the LPT port. Make sure that the BIOS LPT protocol settings are
compatible with the settings selected for the LPT port. "Compatibility mode" is recommended.
• Run the Daq Configuration applet from the Windows Control Panel. Make sure the device is
configured to the appropriate LPT port with the appropriate protocol. Run the device test and if it fails
try other protocols for the device. Be sure to click on
to apply the settings, before re-running
the test.
• Windows NT: Make sure that the driver has been loaded. The installation will configure the operating
system to automatically load the driver at bootup. However, if there is a problem communicating with
the device, the driver can be loaded manually by using the following start sequence from a DOS shell:
NET START WAVEBK
. To unload the driver manually use the following sequence:
NET STOP
WAVEBK
