module is passed out from the divider module and, accordingly, the frequency is halved. If a

post-divider of 1 is selected every signal received from the multiplier module is passed out un-

changed from the divider module.

Setting the Parameters Using Basler pylon

You can configure the frequency converter module from within your application by using a dynamic

API. The following code snippet illustrates setting parameter values:

INodeMap &Control = *Camera.GetNodeMap();

// possible values for FrequencyConverterInputSource:

// CC1

// CC2

// CC3

// CC4

CEnumerationPtr(Control.GetNode("FrequencyConverterInputSource"))-

>FromString("CC1");

// ranges for divider and multiplier:

// divider : 1...128

// multiplier: 1...32

CIntegerPtr(Control.GetNode("FrequencyConverterPreDivider"))->SetValue(4);

CIntegerPtr(Control.GetNode("FrequencyConverterMultiplier"))->SetValue(17);

CIntegerPtr(Control.GetNode("FrequencyConverterPostDivider"))->SetValue(1);

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

Setting the Parameters Using Direct Register Access

To set the parameters needed to configure the frequency converter module via direct register

access:

 Select the source signal for frequency converstion by setting the related value of the

Frequency Converter Signal Source register.

 Set the desired frequency value of the Frequency Converter Pre Divider register.

 If you want to perform signal alignment (see above) you can set the value of the Frequency

Converter Signal Alignment register.

 To avoid overtriggering, we recommend to set the Frequency Converter Prevent Overtrigger

You can use the frequency converter to multiply the original signal frequency by a

fractional value. We recommend multiplying the frequency by the enumerator

value using the multiplier module and dividing the resulting frequency by the

denominator value using the post-divider module.
