The advantages of shaft encoder are as follows:
●
Encoder output pulse frequency is proportional to rotating speed.
●
The output pulse acts as a trigger signal for the device.
●
Synchronize acquisition speed and sample movement of device.
●
Non-uniform motion can also be a perfect match.
●
A trigger signal can be set as acquiring multiple lines or multiple frames with adjustable ratio.
You should go to
Encoder Control
to select the signal source of signal A and signal B via
Encoder
Source A
and
Encoder Source B
.

Note
●
After selecting
Encoder Module Out
as the trigger source in line trigger mode, you can select
LineIn0 or LineIn1 for
Encoder Source A
and
Encoder Source B
only. And you can select LineIn2
as the trigger source only in frame trigger.
●
For different models of the device, the specific parameters may differ, and the actual device you
purchased shall prevail.
