32-Bit WaveView Issues
•
The 32-bit version of WaveView uses a default scheme whereby buffer allocation is dynamic depending
on the amount of physical memory on the computer. An advanced feature is available in this release to
let the user have more control of the buffer allocation. Generally, better performance will be obtained
by increasing the amount of RAM. This allows fewer swaps of VM (virtual memory) to the drive thus
allowing the possibility of greater performance. However, VM management during acquisition
configuration for large acquisitions may cause WaveView to take a significant amount of time to
configure the acquisition.
•
Acquisition parameters can no longer be changed during an active acquisition. The 16-bit version of
WaveView allowed the changing of configuration parameters during an acquisition.
•
Scope scale changes do not become effective until the focus changes. This is best accomplished by
hitting
<Enter>
.
•
International settings are supported, but some text boxes may not completely show the comma when it is
used as the decimal place holder.
•
The Scope Mode’s print resolution is determined by the host computer’s video driver. Some graphics
drivers may require adjustment of the resolution and/or color palette for proper print operation. For
some printers, better output is attained by changing the printer's dithering setting to "None".
•
Text boxes for the filter settings may not display the proper setting if the number entered must be
rounded to the nearest filter setting. This is a problem only with the number displayed and does not
affect the actual filter setting passed down to the driver.
•
Conversion to Snap Master format from the menu option is not supported. Snap Master format
conversion does work properly when done as part of a direct-to-disk acquisition.
Windows 95/98/Me Issues
This section only applies to Windows 95/98/Me installations.
Resource Settings
If WaveBook fails to communicate or has problems transferring data, there may be a resource conflict with
other devices within the system. Take the following steps if this appears to be the case.
ECP (Enhanced Capabilities Port) Setup
If the WaveBook fails to communicate in ECP mode, make certain that the WaveBook hardware is actually
capable of ECP communications. This can be done as follows:
1.
Locate the LPT port communications chip on the main board, near the connector that the parallel
cable connects to. The chip is relatively large and is stamped “262-0301” or “262-0301, rev B.”
A 262-0301 rev. B" chip supports ECP, the earlier rev does not. Contact the factory in regard to
upgrading.
Note that most units purchased before July 2000 do not have ECP support
.
2.
Verify the parallel port hardware is in ECP mode. For ports built into the computer’s
motherboard, the port is usually configured using the computer’s BIOS setup utility (accessible
during computer start up). See your computer's specific documentation regarding accessing the
BIOS setup utility and configuring peripherals.
3.
Verify the parallel port is configured [in the Windows Control Panel] as an "ECP parallel port"
and not "Parallel port."
Windows95/98/Me users can follow the steps below in regard to locating parallel port resource
information.
