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 line scan camera.
 Synchronize acquisition speed and sample movement of camera.
 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.
Follow steps below to set shaft encoder control.
Steps:
1. Click Encoder Control, and set Encoder Source A and Encoder Source B according to actual
demands.
2. Set Encoder Trigger Mode.
 Any Direction means that both forward and backward direction will trigger.
 Forward Only mean that only forward direction will trigger.
 Backward Only mean that only backward direction will trigger.
The 2K camera outputs one signal in one source signal, and the 4K and 8K cameras output four
signal in one source signal.
3. (Optional) Regarding MV-CL021-40GM and MV-CL022-40GC cameras, you can set Encoder
Trigger Frequency to let the camera output multiple signals, including 1 Tick, 2 Tick and 4
Ticks.
