Table 22: Binary Job Selection in JobIOSelect mode
The Job selection bits must be valid during the complete mark. As soon as a new combination is applied the current running job will be interrupted and the new job - if valid - will be loaded.
Additional JobIO Modes:
JobIOSelectExt: Enables the selection of 255 jobs with the Extension connector of the USC-2. DigiIn_0 - DigiIn_7 have to be used.
JobIOSelectInt: A pre-defined job will be selected after boot, for configuration see FlashMode.
Please read here for important information on the JobIOSelect mode in Flash mode:
1.If trying to start marking via start trigger (OptoIn_0) when no Job has been selected or the Job Selection is not valid, nothing will happen.
2.If a Job is selected with the binary job selection pins it is not possible to leave JobIOSelect mode and it is not possible to change the FlashMode.
3.If the command SVG is sent the FM status will be saved and remain even after re-powering the USC-2 card.
