3.6.3. Configuring the Real Time Clock
The 9625LG Series Keyer contains a real time clock that is used to drive the clock display logos that
can be placed on the screen. This battery backed up real time clock (known as RTC) free runs on an
internal oscillator and can be set from the front panel. When the 9625LG Series Keyer is powered up
with a valid video input, a separate clock (known as the UTC) is initialized from the RTC and maintains
Universal Co-ordinated time (UTC) accurately from the video input so that it will not drift. The 9625LG
Series Keyer automatically updates the RTC clock from the UTC clock to minimize long-term time drift.
In order to keep the UTC clock in sync with your house master time code it should also be locked to
incoming linear time code connected to the LTC IN connector. The UTC clock time is internally
maintained as Universal Co-ordinated time (UTC), but it can also be adjusted for time zone offsets
from UTC and for daylight saving time, and displayed as local time (Local). The Time Setup sub-
menus of the General setup menu are used to configure the real time clock and display the UTC and
Local times.

The Reference Setup Type menu item is used to select the timing reference
for the 9625LG Series Keyer. This menu item is not available on early
HD9625LG units.
Select In Video to use the SDI video connected to the INPUT BNC as the
timing reference.
Select In Genloc to use the analog video connected to the REF IN BNC as
the timing reference.
This menu item allows you to set the horizontal timing of the output video
with respect to the reference input. Setting this control to 0 keeps the
output video in time with the reference.
Increasing the value will delay the output video in one-sample increments.
This menu item allows you to set the vertical timing of the output video with
respect to the reference input. Setting this control to 0 keeps the output
video in time with the reference.
Increasing the value will delay the output video in one-line increments.
