A solid-state removable USB flash drive can be used with the machine for the transfer of track recordings and production reporting data. Curves that have been recorded may be transferred to this device and subsequently read by an IBM compatible PC equipped with the optional System V Lining System office version (USB port required). The alignment of curves may be viewed in the office environment, modified or engineered as desired, saved to removable flash drive, and returned to the machine for use. Upon insertion of the USB flash drive, curve data files transfer automatically, updating the information both on the machine and on the removable device.
