Timer

Timers were introduced for advanced control of internal camera signals.
On Baumer HXC cameras the timer configuration includes four components:
Setting
Description
TimerTriggerSource
This feature provides a source selection for each timer.
TimerTriggerActivation
This feature selects that part of the trigger signal (edges or
states) that activates the timer.
TimerDelay
This feature represents the interval between incoming trigger
signal and the start of the timer.
TimerDuration
By this feature the activation time of the timer is adjustable.
Different Timer sources can be used:
Line0
Exposure Start
Line1
Exposure End
Line2
Frame Start
TriggerSkipped
Frame End
SW-Trigger
For example the using of a timer allows you to control the flash signal in that way, that the
illumination does not start synchronized to the sensor exposure but a predefined interval
earlier.
For this example you must set the following conditions:
