Configuring Ranger E and D
Use enable = 0
(no enable sensitivity)
The camera acquires scans continuously.
Use enable = 1
(level sensitive)
A new scan series starts each time the Enable input
has a high level as input, see figure below.
Multiple enable flanks are ignored until all scans (scan
height parameter) have been acquired
NOTE: For the very first profile the camera requires not
only a high level but also a rising flank
Use enable = 2
(rising flank sensitive)
Camera starts scanning on positive edge on the enable
signal.
Multiple enable trigs are ignored until all scans (scan
height parameter) have been acquired.
When all scans (scan height parameter) have been
acquired, the camera waits for a new rising flank, see
below.
Use enable = 3
(level sensitive with
guaranteed end of scan
in mark)
Similar to Use enable = 1 (level sensitive), but checks
the Enable input state of the last scan in the series.
If the Enable input was high for the very last scan, the
Ranger makes another series of scans even if the En-
able is low when the new series is started.
Suitable when using the status of the Enable signal to
detect the end of the object, for example when scan-
ning objects of varying lengths. In this mode the PC will
receive at least one profile where the status of the En-
able signal is 0 in the embedded Mark data.
This mode is only available in measurement mode
where enable information can be added with mark.
Note that it is advisable to set the Scan height parameter in the camera to the same
values as the Profiles per buffer in Ranger Studio/Framegrabber API to keep the image
synchronized and receive a full image after the image capture is completed
