Prosilica GX Technical Manual V2.3.1
The camera can also be programmed to capture an image at some programmable
delay time after the trigger event. These signals can be driven from 5 V to 24 V
with a minimum current source of 5 mA.
Output signals
Output signals can be configured to active high or active low. The internal camera
signals are listed as follows:
Figure 45: Input trigger, camera internal circuit
Avago HCLP-063L
Avago HCPL-063L are optically coupled gates that combine a GaAsP light emitting
diode and an integrated high gain photo detector. These are used for the opto-
isolated camera inputs.
Exposing
Corresponds to when camera is integrating light
Trigger Ready
Indicates when the camera will accept a trigger signal
Trigger Input
A relay of the trigger input signal used to “daisy chain” the
trigger signal for multiple cameras
Readout
Valid when camera is reading out data
Imaging
Valid when camera is exposing or reading out
Strobe
Programmable pulse based on one of the above events
GPO
User programmable binary output
