FRAMOS Industrial Depth Camera D400e Series - User Manual
Version 1.6.0
from 2021-10-15 45 of 64
8.8.5 Output Trigger Enabled
Output Trigger Enabled feature switches between the synchronization signal VSYNC (described in
FRAMOS Industrial Depth Camera D400e Series - External Event Camera Synchronization
[Ref-2])
and user controllable output.
When enabled VSYNC is selected as M8 Pin 3 driver. VSYNC drives pin in all Inter Cam Sync
modes.
When disabled, user can change the state of the M8 Pin 3 with the User Output Level feature.
8.8.6 User Output Level
Enables the user to set the signal level of a M8 Pin 3 (Opto-Isolated Output) to the low or high
voltage level. This can be used to control the external lighting or other devices.
User Output Level is active in all Inter Cam Sync modes when Output Trigger Enabled is disabled.
Output Trigger Enabled and User Output Level features behavior are shown in Figure 20.

8.8.7 Line Debouncer Time
The Line Debouncer Time feature defines the minimum interval in microseconds that an input signal
on camera digital input pin must remain active to be recognized as a valid signal. The Line
Debouncer Time is used to prevent possible unwanted trigger events by eliminating short pulses or
noise that could easily be interpreted as a trigger signal.
The Line Debouncer Time functionality is shown in Figure 21. Trigger signal has three glitches that
are ignored because the width of these signals is shorter than the Line Debouncer Time. The fourth
signal is accepted as a valid trigger signal as its width is longer than the Line Debouncer Time.
The Line Debouncer Time effectively increases delay time between the external trigger (signal on
digital input pin) and the internal trigger that is used to start the camera event, so it should be set
large enough to filter unwanted glitches, but small enough to keep the delay as small as possible.
