backward accidently during measurement, and click Execute in Encoder Reverse Counter
Reset to let the camera to output images again.
7.6.4 Set Frequency Converter Control
If the camera enables the frame trigger or the line trigger, you can select Frequency Converter as
trigger source. The hardware signal trigger or shaft encoder control signal can be converted into
the signal frequency of frame trigger or line trigger by camera’s frequency converter module.
The frequency converter module includes PreDivider, Multiplier and PostDivider. The signal after
being processed by these 3 modules is the camera’s final trigger signal.

PreDivider
The input signal first enters the PreDivider module, which reduces source signal frequency via
integer division, and then the signal is sent to the Multiplier module.
The PreDivider module reduces periodic jitter on the input signal, and signals above 100 kHz must
go through the PreDivider module to reduce the frequency for the Multiplier can only receive
signals in the range of 10 Hz to 100 kHz frequency range. The periodic jitter of shaft encoder signal
is accepted.

Multiplier
After the signal is processed by the PreDivider, it is sent to the Multiplier. The Multiplier multiplies
the signal by an integer to increase its signal frequency, and then the signal is sent to the
PostDivider.
Parameter can be set as rising or falling edge. If a rising edge is set, each rising edge of the signal
coming from the PreDivider will be locked to match the signal of the rising edge, and vice versa.
During this process, make sure do not increase signal frequency via too larger multipliers to avoid
trigger signal frequency beyond the max. line rate of the camera. Even if a smaller multiplier is
selected, an excessively high frequency may be generated in the frequency adjustment, exceeding
the max. line rate of the camera.

PostDivider
PostDivider reduces signal frequency via an integer factor, and uses the newly generated frequency
signal as the camera's trigger signal.
Follow steps below to set frequency converter control.
Steps:
1. Click Acquisition Control > Trigger Selector.
2. Select Line Start or Frame Burst Start as Trigger Selector, and On as Trigger Mode.
3. Select Frequency Converter as Trigger Source according to actual demands.
