I’ve been asked recently how many punches a control can hold, and what happens when that number is reached. The information in the BSF-7 / BSF-8 product brochure is a bit unclear, so I asked SPORTident directly, and here’s the answer:
If it’s a regular control, not a download control or a printer control, it can hold a maximum of 21802 punches. If more are punched, then the oldest are overwritten as new ones are added to the control.
If it’s a download or a printer control, where the entire list of punches on an SI-Card are stored in the control, the maximum that control can hold is approximately 1000 SI-Cards. This depends on which SI-Cards it holds, as the contents SI-10 and SI-11 takes up more memory than the contents of an SI-8 card. The download control also overwrites the oldest downloaded SI-Card contents as the next SI-Card is downloaded.
