5.5.3 Interface X1 - Encoder
5.5.3.1 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.
