5.5.1 Interface X1 (Encoder)
5.5.1.1 Description and configuration
The interface “X1” provides the connection of a shaft encoder.
Due to the input for which you can set the software individually, the encoders can be
connected according to different norms without an additional converter.
Note: For variable product speed you have to use a shaft encoder to synchronize the
printing speed or to control the constant font width.
