A5.18 Log Tab
The ‘Log’ Tab Screen displays the size of each type of data block and the time it was recorded.
When viewed in compressed time (fast forward), the size of data blocks written at each time-
period is displayed, but the actual NMEA strings are not. When played back in normal time, the
‘Log’ Tab Screen will also display the NMEA strings.
‘Log’ information can be controlled via the Controls toolbar. To scroll illustrated information, press
the ‘Pause’ button on the Controls toolbar and use the ‘Log’ scrollbar to navigate.
