General high-speed discussion / Control Chronos 1.4 via Laptop
« on: July 10, 2019, 04:16:34 AM »
Hi,

Is there currently a way to control the Chronos 1.4 via a laptop remotely (e.g laptop is connected to the camera and then triggering/recording/saving video can be controlled via laptop).

In my experiment manually having to save video really slows the process.

Thanks

Hi,
The default minimum resolution is 336x96 which gives 38565 fps.
I have noticed that I can take it down to 192x96 and maintain the same fps.
Now when I change resolutions, always keeping the product of the width (x) and height (y) less than 32256 (which is 336x96) I keep getting frame rates below 38565. Such as 256x124 gives 30230 fps.

Is it possible to maintain the maximum fps of 38565 and follow the above rule of any resolution combo of xy less than 32256?

My aim is to record at the maximum frame rate but either is a square resolution or in a verticale slit. To clarify the resolution 336x96 would be a horizontal slit.

Thanks for any help.

Hi,
I have two Chronos 1.4 Monochrome 32GB Cameras with the software version 0.3.0 and build version 30e36f.

I was testing out triggers yesterday to figure out what trigger delay options work.
I tested at 1280x1024 1057fps.

Results:

The End Trigger works fine (I used a trigger that sends a pulse).

When I started testing the Exposure Trigger (Start Trigger) it would not work.
I tested the following: Recording Modes Normal and Segmented
Trigger Delay:
  • Post Trigger 100%
  • Pre Trigger 100%
For Post-Trigger 100% I expected a normal recording after I pressed the trigger.
For Pre-Trigger 100% I expected no recording (as its a Start Trigger)
In both cases, I got a 1-second recording.

My attempt at troubleshooting was to play with the pull-up options and the invert option none of which helped. I switched to a function generator for a pulse input (3.0V and the camera was set to a 2.5V threshold (not inverted)). This did not help either.

Then I tested Gated Trigger.
I tested the following: Recording Modes Gated.
I set the pre-record to 1 second.
I used the above-mentioned oscilloscope to send in a pulse of amplitude 3.0V (above the 2.5V threshold).
The pulse width was 2 seconds and repeated every 3 seconds (so a total of 5 seconds of which 2 seconds on 3.0V and 3 seconds on 0V).
Here again, I got a 1 frame recording. Furthermore, the image was near-white (oversaturated) whereas the recordings in Normal mode were not saturated.

I have been looking through this forum to see if I can find a solution to this problem however I have not found one yet. Can anyone please advise?
Both of the cameras have this exact same problem (tested under identical conditions). As a result, I suspect a software issue or some lack of understanding on my part.

Edit: If I have posted in the wrong forum section please let me know I'll move the post
