Physical Encoder
Select Disable or Enable from the drop-down list:

Disable: External encoder is disabled, and internal encoder is active

Enable: A physical encoder is connected to the Encoder input and is
enabled
Encoder Step

Encoder
Resolution Displays the encoder/tachometer resolution in pulses per inch (PPI) based on the
Encoder Step calculation. This field cannot be edited.
Conveyor Speed
(m/sec)
When Physical Encoder is Disabled , enter the conveyor speed in meters per
second in the field provided (see formula below).
When
Physical Encoder is Enabled , enter the maximum belt speed using the
formula below. Setting the belt speed too high will affect image quality; setting it
too low will give you an exceeded maximum line rate error when the belt exceeds
this setting.
Formula: Max conveyor speed x 1.05
Advanced
Encoder Settings The settings are available when Physical Encoder is set to Enabled above.
Direct Encoder Select Disable or Enable from the drop-down list. Direct encoder is a high-
resolution encoder/tachometer used in start/stop applications.
