– LED Strobe Controller Family | Doc. v2.2.1
7.6.1.
Off
The controller is in idle mode and does not respond to any input triggers. There is no voltage
on any output line.
7.6.2.
External Trigger
In the
External Trigger
mode, the device is ready to accept external trigger signals and
generates a very precise output pulse according to the user configuration. The
External Trigger
mode is the most precise mode and the usual way of pulse operation.
7.6.3.
Software Trigger
In
Software Trigger
mode the Strobe Controller is waiting for software triggers to generate
output pulses according to the user configuration. These triggers are issued by the PC using
the communication interface and is for that reason not as precise as the
External Trigger
mode.
In
Software Trigger
mode devices do not respond to any external trigger inputs.
7.6.4.
Continuous
In
Continuous
operation mode the output provides a constant current. The device operates as
a DC current source, configured by the user. As soon as the parameters have been sent to the
Strobe Controller, the output is immediately driven according to the set voltage and current.
The timing parameters are ignored in this mode.
7.6.5.
External Switch
In
External Switch
mode the device acts as a switch. The Strobe Controller is armed and
generates output pulses according to the external trigger signal. In contrast to the
External
Trigger
mode, the pulse length is defined by the trigger pulse length. If a trigger arrives, the
device will send continuous current on the output if the trigger is active. The timing parameters
are not used in this mode.
Note:
As the pulse duration is not controllable in this mode, the maximum voltage and current
levels are same as in the
Continuous
operating mode.
The precision is slightly lower than in
External Trigger
mode, which is to prefer if possible.
7.6.6.
Internal Trigger
The
Internal Trigger
mode allows to generate constant triggering by the strobe controller itself,
which can be used to drive one or more outputs. The signal is defined by the configured On-
Time, Off-Time and Delay-Time. In this mode any external or software triggers are ignored.
