Scanning Configuration Tab

Close Previous Collection on Scan Start

if checked will close the previous scan and ask if you’d like to save the data before closing. To close without being asked to save make sure Discard Previous Data is checked. If not checked all previous scans will be left open and accessible by the thumbnails on the right side of the main window.

Update Thumbnail during Scanning

allows you to see scan progression on the thumbnails in real time. This feature is useful if you have only one monitor or are using the second monitor for analysis of other images.

OverScan

Sets an amount of extra motion added to the scan length. This amount is added to both ends of Linear and Tray Scans. It ensures that the scanner will move beyond the encoder trigger region on each scan line.

Display A-Scans during Scan

Will update the oscilloscope during the scan. This is useful for real time correction of Follower and Gate placement/length

No. of Points Per Download

Number of points to collect on the A/D board before downloading to memory. This also sets how many triggers it takes for the scope to update during a scan. If the number of points per scan line is less than this amount, the scan will attempt to download at least once per line.

Changing Acceleration with Velocity

Change Acceleration when Velocity Changes

Connects the slider bar with both velocity and acceleration by a factor of your choosing.

Disable Updates during a Scan

if checked ODIS will not update the image of the current scan until after the scan has completed. If not checked will allow you to choose how many lines should be scanned before your image is updated. Disabling updates or increasing # of scan lines before update may speed up scan times on scans requiring larger data collection.

Align to Zero (Rotational Scans)

If checked, the system will attempt to find the Zero position on the turntable before scanning, and use said position to align the resulting image data. Note: this will only work on a turntable that is wired to send a "Zero" indication to the motor controller.

• Software Only

If checked, the system will attempt to calculate the zero position of the Rotational axis to align the resulting image data.

After Scan, Return To...

Allows you to choose the place the transducer will return to after completing a scan.

• Center – returns to the center of the scan area
• Corner – returns to the top left corner of the scan area
• Home – Returns to your system’s home position
• None – leaves the transducer where it finishes.

Focusing Configuration Tab

Reverse Gate Tracking Direction

When tracking is turned on, changes the direction the gates move when you raise or lower your Z-Axis.

Move Scope View when Gate Tracking

if checked moves the waveform when the focus changes. If not checked, leaves the wave form in place when changing focus.

Keep Focus Changes

will keep your current focus if changed during a scan.

Auto-Center

Allows you to choose the velocity of the auto-center procedure.

Tray Scans

Axis	N/A	x	x

Tray Scan Configuration Tab

Update Tray Scans Every Row

If checked, the Tray Scan image will only update after a row has completed. Otherwise, the Tray Scan will update every scan line (unless image updates are disabled entirely).

Wait for Row Step to Complete

If checked, the Scan Axis will not move until the jump between Tray rows has completed. Otherwise, scanning of the next row starts as soon as the row jump starts.

When Scanning Each Chip Individually

Water Path Calibration Range (System Units)

The distance the Focus Axis will move when calibrating the water path. If the transducer will be very close to the surface of the part, make sure this value is small.

Number of Water Path Tests

The number of checks that will be made to see if the follower is crossed when checking for Water Path.

Recall Water Path Timeout(seconds)

The amount of time the system will wait in order to get the Water Path values for Autofocus. If no results can be collected in the specified time period, Autofocus will not change the Focus axis position.

Warnings and Errors

Feature	Example	ODIS-IC?	ODIS-NDT?	Description
Axis	N/A	x	x

Warnings and Errors Configuration Tab

Allows the operator to turn off or adjust pop-up warnings. These should be left on until users are comfortable with the software.

Show Warnings before Starting Scan

Uncheck to hide all warnings. Keep checked to specify which warnings will be displayed before the scan starts.

Scan Axis Warning

This will display the current scan axis before starting the scan. The user has an opportunity to cancel the scan if the wrong scan axis is set (e.g., Y-Axis instead of X-Axis)

Scan Start Change Warning

This will display a warning if the current position of the axes is not at a scan start or center. The user has the opportunity to set the current position as the scan start or center.

Focus Change Warning

This will display a warning if the current Focus axis is not at the position that was defined as the focus for the previous scan. The user will have the opportunity to recall the focus or keep the current one.

Range Warning

this will display a warning if the current scan is outside the range as specified in Motors.xml. The user will have an opportunity to cancel the scan.

Error Bounds

the maximum error allowed before a position error is triggered.

Scanline Timeout

when scanning, if the scan line collection takes more than the specified number of seconds, a timeout error will be generated.

On Scanline Error

the options here determine the reaction of the system when errors occur duing a scan.

Abort Scan	Stop the scan immediately and display an error message.
Ignore and Continue	Ignore the error and proceed with the next scan line regardless.
Rescan Line	Forces a rescan of the current line. There are two sub-options: Reconcile: force a reconcile of the motor and encoder (based on current Reconcile options) Lower Speed: reduce the scan velocity by the specified percentage.

Advanced Scan Settings Configuration Tab

Reconcile before Scan

If checked, the system will reconcile the motor and encoder positions before a scan. The way it reconciles depends on the Reconcile Options (see below).

Check End of Motion

If checked, the system will wait until the step axis has come to a complete stop before starting the next scan line.

End of Motion Delay

This forces the system to wait the specified number of milliseconds before starting the next scan line.

Use Quick Setup

If checked, The Simple Mode interface will have additional checkboxes added that enable and disable A/D boards, as well as set them for External triggering. Should only be used with a system that has multiple A/D boards.

Enable Surface Mapping

If checked, allows for the mapping of a warped image for contour scanning. Note: drift may occur and repeat scans may have varying results if contour scan kit is not present on your system.

"On Reconcile" options

The user can reconcile in two ways: set the Motor Position to the current Encoder position, or vice-versa. It is recommended that the user set the Motor Position to the Encoder position unless otherwise directed by OKOS.
