8.2.4.2 Setting the Timer Delay Time

There are two ways to set the delay time for timer 1: by setting "raw" values or by setting an

"absolute value". You can use whichever method you prefer to set the delay time.

Setting the Delay Time with Raw Values

When the delay time for timer 1 is set using "raw" values, the delay time will be determined by a

combination of two elements. The first element is the value of the Timer Delay Raw parameter, and

the second element is the Timer Delay Time Base. The delay time is the product of these two

elements:

Delay Time = (Timer Delay Raw Parameter Value) x (Timer Delay Time Base)

By default, the Timer Delay Time Base is fixed at 1 µs. Typically, the delay time is adjusted by setting

the Timer Delay Raw parameter value.

The Timer Delay Raw parameter value can range from 0 to 4095. So if the value is set to 100, for

example, the timer delay will be 100 x 1 µs or 100 µs.

To set the delay for timer 1:

 Use the Timer Selector to select timer 1.

 Set the value of the Timer Delay Raw parameter.

You can set the Timer Selector and the Timer Delay Raw parameter value from within your

application software by using the pylon API. The following code snippet illustrates using the API to

set the selector and the parameter value:

Camera.TimerSelector.SetValue( TimerSelector_Timer1 );

Camera.TimerDelayRaw.SetValue( 100 );

For detailed information about using the pylon API, refer to the Basler pylon Programmer’s Guide

and API Reference.

You can also use the Basler pylon Viewer application to easily set the parameters.

Changing the Delay Time Base

By default, the Timer Delay Time Base is fixed at 1 µs (minimum value), and the timer delay is

normally adjusted by setting the value of the Timer Delay Raw parameter. However, if you require

a delay time that is longer than what you can achieve by changing the value of the Timer Delay Raw

parameter alone, the Timer Delay Time Base Abs parameter can be used to change the delay time

base.

The Timer Delay Time Base Abs parameter value sets the delay time base in µs. The default is 1 µs

and it can be changed in 1 µs increments.

You can set the Timer Delay Time Base Abs parameter value from within your application software

by using the pylon API. The following code snippet illustrates using the API to set the parameter

value:

Camera.TimerDelayTimebaseAbs.SetValue( 5 );

1 2 ... 95 96 97 98 99 100 101 102 103 104 105 ... 165 166
