Read Order Specifies the order in which enabled Configs will be tried until a successful
read is obtained.
SELECTION DESCRIPTION
Last Best
(default) Configs will be tried in the order they scored (from highest to lowest) during the last read until a
passed score is read.
In Order Configs will be tried in numerical order (0-9), regardless of how they scored during the most recent
read.
Disable Acquire
Disables image acquisition to allow a test read from the last image acquired, or from an
image file, when the wafer reader is Offline. The Light Mode and Light Power settings are
disabled, as are the Acquire and Live buttons.
To Read from a Saved Image File:
1 Check the Disable Acquire checkbox.
2 Load a valid .BMP or .JPG image file (640 x 480, 8-bit) using one the following
methods:
With the In-Sight PC Host open, drag-and-drop an image file onto the
spreadsheet. Or, open the Save & Load dialog (System > Save & Load) and
select an image from a different In-Sight host on the network.
Open an FTP connection to the wafer reader (for instructions see Appendix A:
Updating the Wafer Reader’s Firmware). Drag-and-drop the image file into the
FTP window of the web browser, or use the
mput command from an FTP
prompt.
NOTE You do not need to rename the image file before loading it on the wafer reader. The wafer
reader will automatically copy the .BMP or .JPG file to the built-in file names, IMAGE.BMP or
IMAGE.JPG, respectively.
3 Click the Read button on either the Setup or Run tab to read from the image file.
4 Repeat step 2 to read from a different image file, or uncheck Disable Acquire in the
Options tab to return the wafer reader to normal operation.
