Q: What is needed to run a Meade Pictor 416XT
or 1616XT via SCSI?
A: You need an Adaptec 1480A or 2940UW SCSI adapter. Only
these adapters will work with 32-bit programs like MaxIm DL/CCD
because of compatibility issues with the camera. Other adapters such as
the 1460 will connect but will fail to download images.
You must install both the SCSI drivers and the ASPI drivers. If the
camera does not appear as a scanner in the Windows Device Manager, it will
not work.

Q: How do I get the Pictor SCSI interface to
work under Windows 2000?
A: Windows 2000 includes the needed SCSI drivers but does not
include the needed ASPI drivers. The ASPI driver can be downloaded
from the Adaptec web site at http://www.adaptec.com/support/files/upgrades.html.
Download and install ASPI32.EXE.
Windows 2000 may ask for drivers for the Pictor camera every time you
boot. If this occurs, go to the Windows Device Manager and disable the
Pictor camera (listed under Scanners). This doesn't actually disable the
camera, but it will prevent Windows from trying to load non-existent
drivers.

Q: I occasionally get an error when downloading
images with the Pictor SCSI interface. How can I avoid this?
A: Simply increase the "Extra Delay" setting in
the Setup dialog box.

Q: Are any special system settings required for
SBIG cameras?
A: For parallel port cameras we recommend changing the BIOS setting for the parallel
port to "Standard" instead of "ECP", "EPP",
or "Bidirectional".

Q: My USB interface camera seems to lock up the application occasionally. What is wrong?
A: The USB protocol is designed to provide completely error-free communications bewteen the
computer and the peripheral (camera). Unfortunately this does not account for peripherals that do not respond correctly,
whether due to bad drivers sending the wrong message, or incorrect firmware in the peripheral itself.
Normally such problems would be detected by an "I/O timeout", where the operating system gives up after
trying for a time; unfortunately this basic precaution was not included in
Windows. As a result, if this type of error occurs the application will lock up.
If this happens, briefly unplug the USB cable to unlock the application.
You should also contact the camera vendor for assistance in resolving the problem.
