sane-artec_eplus48u - SANE backend for the scanner Artec E+ 48U and re-badged models
|
|
<A NAME="lbAC"> </A>
|
|
<H2>DESCRIPTION</H2>
|
|
|
|
The
|
|
<B>sane-artec_eplus48u</B>
|
|
|
|
library implements a SANE (Scanner Access Now Easy) backend that provides
|
|
access to several USB flatbed scanners using the GT6816 chipset like the Artec E+ 48U.
|
|
These scanners have a contact image sensor (CIS) and an USB interface.
|
|
<P>
|
|
|
|
A complete list of supported devices can be found on
|
|
<I><A HREF="http://www.sane-project.org/sane-supported-devices.html">http://www.sane-project.org/sane-supported-devices.html</A></I>.
|
|
|
|
<P>
|
|
|
|
This is ALPHA software. Especially if you test new or untested scanners, keep
|
|
your hand at the scanner's plug and unplug it, if the head bumps at the end of
|
|
the scan area.
|
|
<P>
|
|
|
|
If you own a scanner other than the ones mentioned on the list that works with this
|
|
backend, please let us know this by sending the scanner's exact model name and
|
|
the USB vendor and product ids (e.g. from /proc/bus/usb/devices,
|
|
sane-find-scanner or syslog) to me. Even if the scanner's name is only
|
|
slightly different from the models mentioned above, please let me know.
|
|

|
<H2>KERNEL ISSUES</H2>
|
|
|
|
If libusb-0.1.6 or later is installed, this section can be skipped. The
|
|
scanner should be found by sane-find-scanner without further actions. For
|
|
setting permissions and general USB information look at <A HREF="/cgi-bin/man/man2html?5+sane-usb">sane-usb</A>(5).
|
|
<P>
|
|
|
|
When you are using the scanner module, a Linux kernel 2.4.12 or newer is
|
|
required.
|
|
<P>

|
|
<H2>FIRMWARE FILE</H2>
|
|
|
|
You need a firmware file for your scanner. That's a small file containing
|
|
software that will be uploaded to the scanner's memory. For the scanners
|
|
mentioned above, it's usually named Artec48.usb or 1200.usb. You can find it on
|
|
the installation CD that was provided by the manufacturer, normally in the
|
|
directory Win98, WinMe or similar. If the Windows-driver is installed on your
|
|
computer, then you can also find the firmware file under
|
|
c:\windows\system32\drivers.

|

|
|
<H2>CONFIGURATION</H2>
|
|
|
|
The contents of the
|
|
<I>artec_eplus48u.conf</I>
|
|
|
|
file is a list of usb lines containing vendor and product ids that correspond
|
|
to USB scanners. The file can also contain option lines. Empty lines and
|
|
lines starting with a hash mark (#) are ignored. The scanners are
|
|
autodetected by
|
|
<I>usb vendor_id product_id</I>
|
|
|
|
statements which are already included into
|
|
<I>artec_eplus48u.conf .</I>
|
|
|
|
"vendor_id" and "product_id" are hexadecimal numbers that identify the
|
|
<B>scanner.</B>
|
|
|
|
<P>
|
|
|
|
Every usb section can have additional options
|
|
<DL COMPACT>
|
|
<DT id="1"><B>artecFirmwareFile @DATADIR@/sane/artec_eplus48u/Artec48.usb</B>
|
|
|
|
<DD>
|
|
The path to the firmware file. This option is required.
|
|
<DT id="2"><B>redGamma 1.0</B>
|
|
|

<DD>
|
|
<DT id="3"><B>greenGamma 1.0</B>

|
|
|
|
<DD>
|
|
<DT id="5"><B>masterGamma 1.9</B>
|
|
|
|
<DD>
|
|
These are the default gamma values. If you set the "Defaults" option with a frontend,
|
|
then the gamma options are reset to the values specified here.
|
|
<DT id="6"><B>redOffset 0x28</B>
|
|
|
|
<DD>
|
|
<DT id="7"><B>greenOffset 0x2f</B>
|
|
|
|
<DD>
|
|
<DT id="8"><B>blueOffset 0x2f</B>
|
|
|

<DD>
|
|
<DT id="9"><B>redExposure 0xa7</B>
|
|
|

<DD>
|

<DT id="10"><B>greenExposure 0x116</B>
|
|
|
|
<DD>
|
|
<DT id="11"><B>blueExposure 0xdc</B>
|
|
|
|
<DD>
|
|
These are the default values for offset and exposure time. You can e.g. change them to speed up calibration,
|
|
if you don't want to save the calibration data to disk.
|
|
<DT id="12"><B>vendorString Artec</B>
|
|
|
|
<DD>
|
|
<DT id="13"><B>modelString E+ 48U</B>
|
|
|
|
<DD>
|
|
By default, the scanner is reported as "Artec E+ 48U". If you don't like this, e.g.
|
|
because you have an Tevion MD 9693, then change the options accordingly.

|
|
This environment variable specifies the list of directories that may
|
|
contain the configuration file. Under UNIX, the directories are
|
|
separated by a colon (`:'), under OS/2, they are separated by a
|
|
semi-colon (`;'). If this variable is not set, the configuration file
|
|
is searched in two default directories: first, the current working
|
|
directory (".") and then in /usr/local/etc/sane.d. If the value of the
|
|
environment variable ends with the directory separator character, then
|
|
the default directories are searched after the explicitly specified
|
|
directories. For example, setting
|
|
<B>SANE_CONFIG_DIR</B>
|
|
|
|
to "/tmp/config:" would result in directories "tmp/config", ".", and
|
|
"/usr/local/etc/sane.d" being searched (in this order).
|
|
<DT id="18"><B>SANE_DEBUG_ARTEC_EPLUS48U</B>
|
|

<DD>
|
|
If the library was compiled with debug support enabled, this
|
|
environment variable controls the debug level for this backend. Higher
|
|
debug levels increase the verbosity of the output.
|
|
<P>
|
|
Example:
|
|
export SANE_DEBUG_ARTEC_EPLUS48U=3
