Revision 1.5.1
OPERATION
The JAM WINDOW parameter has been added to the Engineering Setup menu. This parameter is
used to ignore the natural differences between 30 Fps and 25 Fps frame numbers within the second.
The frame counting rates of 25 Fps and 30 Fps along with the natural difference between the video
rates of 29.97 and 30 Fps (taking into account the dropped frames) produce an acceptable difference
between the 25 Fps and 30 Fps frame numbers during a given second. Any difference between the
active reader’s input and the generated time code output numbers (accounting for any programmed
OFFSET ) will cause the generator to resynchronize to the reader in translate mode. Under normal
circumstances the factory default setting of “6” frames should be adequate.
Example 1:
Offset: 00:00:01:00
Reader: 01:00:00:00
Generator: 01:00:01:00
Example 2:
Offset: 23:59:59:00
Reader: 01:00:00:00
Generator: 00:59:59:00

In order to Jam sync the generator time to exactly the reader time make sure the
OFFSET is set 00:00:00:00
To access the
OFFSET register press the SHIFT+DISPLAY buttons one or more times. The display
prompt will be OFFS . The ENTER and CLEAR keys are used in conjunction with the numeric keys to
set the value stored in the OFFSET register.
3.4.10. Turning the VITC Generator On
The VITC GEN ON/OFF key is used to turn the VITC keyer on and off. (You must exit the Setup menu
to turn the VITC generator on or off.) When the VITC generator is Off, the program video passes
through the VITC keyer with nothing added. When the VITC generator is On, the VITC will be added to
the program video.
