The internal memory of any data logger is referred to as Local Disk, the Shark logger removable memory is referred to as Flash Card. Note: Before any download can be made, your logger must be visible within the DK-Link program. data view_std_manual v1.4.doc Digitek Spa Digitek Spa
R&S Business Unit Automotive 4.1 – Memory / Shark Via L.Romagnoli, 24 - 41033 Concordia sulla Secchia (Modena) Italy Tel.: +39 0535 57711 (r.a.) - Fax.: +39 0535 54550 Uffici amministrativi: Via G. Brodolini, 35 - Fax.: +39 0535 54533 Email : guest@digitek.it - Internet : http://w w w .digitek.it DATAVIEW Pg. 33/133 The Shark data logger has 2 totally independent memory locations which are written to simultaneously. The Local Disk (internal flash) is either 128Mb or 256Mb, depending on logger specification. The removable flash card memory may be any size as long as it is larger the Auto Lap limit which is typically 40Mb. Lap storage The data is divided within the logger as separate files; the file division is normally created when a lap beacon signal is seen. With this method the user is able to download individual laps rather than removing all of the laps stored in memory. A download of multiple laps only creates a single file on your PC. Latest data - on/off From table Manager the user is able to decide which type of memory management is used. Latest data on – When the logger memory becomes full the oldest lap file is deleted from memory as an entire block Latest data off - When the logger memory becomes full the memory storage stops, new data can only be stored if the Clear data command is used. See section 5.1 Auto lap Limit This is an internally imposed maximum size for any one internal lap file, when the limit of 40Mb (typical Shark setting) is reached a new lap file is automatically created. This Auto lap Limit is needed for data security, systems which do not use a lap timing beacon may fill up the memory without ever seeing a lap beacon signal, the latest data function would then automatically remove the oldest lap file, which in this scenario would be all of the data. The 40Mb Auto lap limit avoids this possible problem. Notes about Auto lap limit The internal channels Time and Space are not incremented by Auto lap limit The LAP counter is not incremented by Auto lap limit The ABS lap counter does increment at the Auto lap limit The LAPTIM message records the time from logger on to the previous Auto lap limit Auto lap limit is applied to Local disk as well as flash card memory. The size of the auto lap limit is a compromise between ensuring that the Auto lap limit does not interfere with the normal lap beacon > lap beacon events and possible data loss resulting from use without a beacon. The maximum data throughput of the Shark at 64,000 bytes per second (typical value) means that at maximum acquisition rate the 40Mb (40,000,000 bytes) / 64,000 = 10minutes (approx) between each Auto lap limit. This would never normally conflict with a race car lap. Memory storage Starting from a logger with empty flash card and empty Local disk, the data is stored to both locations simultaneously. At the point of memory being full, the earliest lap file is deleted from both the Local disk and Flash card. If a blank or partially filled memory card is inserted into a logger with stored data in Local disk memory the 2 storage locations become out of synchronisation. This is not a problem and they both then work independently of each other, this situation also occurs when a flash card of larger memory size is used. The Shark logger does not need the Flash card in order to function. If no card is inserted, the logger can be downloaded in the normal Ethernet method using the Local disk only. When using the Flash card to transfer data, the Local disk memory is mostly redundant and only used as a back up source in case of Flash card failure. data view_std_manual v1.4.doc Digitek Spa Digitek Spa
