Notes on the Timecode Menus
• Video Timecodes count at the frame-rate defined by the video format of the selected video channel.
• LTC Timecodes count at the frame-rate defined by the format selected in the menu. SPG Time and UTC
DateTime are both “FIXED”, counting at 50Hz.
• Each LTC Timecode can be configured, in DashBoard, to report the Date In User Bits . Navigate to the Slot 12:
System Time > LTC # Time tab for this menu.
• GPS DateTime and NTP DateTime are “FIXED”, being displayed at 50Hz - they only count if a GPS or NTP
reference is present.
• Summer DST Event, Winter DST Event and Leap Second Event do not count.
• The system has a battery backed real-time-clock. This runs independently of any other reference. It can maintain
reasonably accurate time over a few days while the unit is powered down. It is NOT to be trusted as reliable
where your application requires accurate time. As the GPS system is so inexpensive, we recommend its use in all
vehicle installations where power may switch on and off regularly.
• Several menu lines are identical between menu screens. Where possible, to avoid obvious repetition, in the
definitions outlined below, identical menu lines are grouped under one definition.
