The SyncBox XL time-synchronizes the CANcardXL:
The SyncBox XL provides a time synchronization signal to the CANcardXL. 2 connectors (Binder 711 series) are included on the SyncBox for this purpose. It is possible to operate a CANcab or LINcab simultaneously with a SyncBox XL. This involves plugging the cab into the SyncBox XL. Automatic detection of the CANcab/LINcab is assured.
