Timer#

The Timer camera feature allows you to configure a timer output signal that goes high on specific camera events and goes low after a specific duration.

Using the Feature#

ace 2, boost, and dart IMX Cameras#

Info

This section tells you how the Counter feature works on ace 2, boost, and dart IMX cameras. For ace classic/U/L cameras, click here.

How It Works#

Two timers are available, Timer 1 and Timer 2.

This is how a timer works:

  • A trigger source event that starts the internal timer occurs.
  • A delay begins to expire.
  • An arm delay begins to expire.
  • When the delay has expired, the timer output signal goes high and stays high for the duration that you have configured.
  • When the duration has expired, the timer output signal goes low.
  • When the arm delay has expired, the camera can receive the next trigger source event.

Timer Operation

Configuring a Timer#

To configure a timer:

  1. Set the TimerSelector parameter to the desired timer, e.g., Timer1.
  2. Set the TimerDuration parameter to the desired timer duration in microseconds.
  3. Set the TimerDelay parameter to the desired timer delay in microseconds.
  4. Set the TimerTriggerArmDelay parameter to the desired arm delay in microseconds.
  5. Set the LineSelector parameter to the output line that you want to use for the timer signal.
    If the line is a GPIO line, the line must be configured as output.
  6. If you selected Timer 1 in step 1, set the LineSource parameter to Timer1Active.
  7. If you selected Timer 2 in step 1, set the LineSource parameter to Timer2Active.

Starting a Timer#

Timer Trigger Source

The TimerTriggerSource parameter allows you to specify which source starts the timer.

To specify the trigger source:

  1. Set the TimerSelector parameter to the desired timer, e.g., Timer1.
  2. Set the TimerTriggerSource parameter to the source that you want to use to start the timer.

Now, the timer starts whenever the camera detects a signal on the selected source.

When started, the timer's status immediately changes from TimerTriggerWait to TimerActive, regardless of the delay set. However, the timer output signal will only go high after the delay has expired.

Example 1: You set the TimerTriggerSource parameter to Line2. Now, the timer starts when the input or output signal on Line 2 changes.

Example 2: You set the TimerTriggerSource parameter to SoftwareSignal1. Now, the timer starts whenever you execute a SoftwareSignalPulse command via channel 1.

Timer Trigger Activation

By default, a timer only starts when a signal on the selected trigger source rises, i.e., when the signal status changes from low to high.

To change this behavior, set the TimerTriggerActivation parameter to one of the following values:

  • RisingEdge (default): The timer starts when the signal rises, i.e., when the signal status changes from low to high.
  • FallingEdge: The timer starts when the signal falls, i.e., when the signal status changes from high to low.
  • AnyEdge: The timer starts when the signal falls or rises.
  • LevelHigh: The timer starts when the signal is high. When the signal changes to low, the timer stops and must be started again.
  • LevelLow: The timer starts when the signal is low. When the signal changes to high, the timer stops and must be started again.

Info

The TimerTriggerActivation parameter is only available for timer trigger sources that can be high (0) or low (1), i.e., an I/O signal or an "Active" signal like ExposureActive.

Resetting a Timer#

To reset a timer, execute the TimerReset command.

The timer's status changes from TimerActive to TimerTriggerWait.

The timer can now be restarted immediately regardless of the arm delay set.

Getting the Status of a Timer#

To get the current status of a timer, get the value of the TimerStatus parameter. This parameter is read-only.

Possible values are:

  • TimerTriggerWait: The timer is waiting to be started.
  • TimerActive: The timer has been started. A timer immediately switches to this state when the trigger source event occurs, regardless of the delay set. If an arm delay is set, the timer remains in the TimerActive state until the arm delay has expired.
  • TimerIdle: The timer is idle. A timer is in this state whenever the TimerTriggerSource parameter is set o Off, i.e., the timer can't be started.

ace classic/U/L Cameras#

Info

This section tells you how the Counter feature works on ace classic/U/L cameras. For ace 2, boost, and dart IMX cameras, click here.

How It Works#

One timer is available, Timer 1. This is how the timer works:

  • A trigger source event (e.g., Exposure Start) that starts the internal timer occurs.
  • A delay begins to expire.
  • When the delay has expired, the timer output signal goes high and stays high for the duration that you have configured.
  • When the signal's duration has expired, the timer output signal goes low.

Timer Operation

Configuring the Timer#

  1. Set the LineSelector parameter to the output line that you want to use for the timer signal.
    If the line is a GPIO line, the line must be configured as output.
  2. Set the LineSource parameter to TimerActive.
  3. Set the TimerTriggerSource parameter to one of the available trigger source events:

    • ExposureStart: The timer starts when the exposure starts.
    • FlashWindowStart: The timer starts when the flash window opens.
  4. Set the TimerDuration parameter to the desired timer duration in microseconds.

  5. Set the TimerDelay parameter to the desired timer delay in microseconds.

Info

On some camera models, you may have to increase the maximum timer duration and timer delay values.

Increasing the Maximum Timer Duration and Delay#

On some camera models, the TimerDuration and TimerDelay parameters are limited to a default maximum value of 4 095.

To increase the maximum timer duration on these models:

  1. Divide the desired timer duration by 4 095 and round up the result to the nearest integer.
    Example: Assume you want to set a timer duration of 50 000 µs. 50000 / 4095 = 12.21 ≈ 13.
  2. Set the TimerDurationTimebaseAbs parameter to the value determined in step 1, in this case 13.
  3. Set the TimerDuration parameter to the desired timer duration, in this case 50 000.
    Internally, the camera calculates the timer duration as follows: TimerDurationRaw x TimerDurationTimebaseAbs = TimerDurationAbs.

To increase the maximum timer delay on these models:

  1. Divide the desired timer delay by 4 095 and round up the result to the nearest integer.
    Example: Assume you want to set a timer delay of 6 000 µs. 6000 / 4095 = 1.47 ≈ 2.
  2. Set the TimerDelayTimebaseAbs parameter to the value determined in step 1, in this case 2.
  3. Set the TimerDelay parameter to the desired timer delay, in this case 6 000.
    Internally, the camera calculates the timer delay as follows: TimerDelayRaw x TimerDelayTimebaseAbs = TimerDelayAbs.

Info

Depending on the TimerDurationTimebaseAbs and TimerDelayTimebaseAbs parameter values, the camera may not be able to achieve the exact timer duration and delay desired.
For example, if you set the TimerDurationTimebaseAbs parameter to 13, the camera can only achieve timer durations that are a multiple of 13. Therefore, if you set the TimerDuration parameter to 50 000 and the TimerDurationTimebaseAbs parameter to 13, the camera will automatically change the setting to the nearest possible value (e.g., 49 998, which is the nearest multiple of 13).

Additional Parameters#

  • TimerSelector: Sets which timer to configure. Because Basler ace classic/U/L cameras support only one timer, this parameter is preset and can't be changed.
