Setting up the 4025TR for Jam Sync to the VTR Time Code
Use the Codes tab of the configuration screen to jam sync the VTR time
code to one of the readers.
The preferred method of configuring the logical Video generator in the
4025TR to Jam sync to the Record VTR's time code is to use the internal
time code generator in the VTR to generate continuous LTC. Connect this
LTC to the LTC reader in the 4025TR. Set the RDR MAPPING menu so
that the Video generator follows the LTC reader, and set the GEN ASSIGN
menu is set to one of the 'LRDR' modes. The Video Time code Offset
register (VOFS) can be programmed to adjust for path delays between the
VTR and the 4025TR.
The VITC from the 4025TR will be slaved to this input and should be
recorded on the VTR directly. (See section 3.9.1 for information about the
use of your VTR's time code generator with film edge numbers.) Audio
time code may be connected to the 4025TR's VITC reader with the use of
an LTC to VITC translator such as the Evertz S621D-LTR.
This configuration prevents the 4025TR from jamming to its own timecode,
which can cause instabilities in the number sequences when the VTR goes
E-E during recording.

Selecting the Lines to Record VITC on - (Except 3-line VITC
Standard)
The 4025TR contains a multi-line VITC generator capable of generating
multiple sets of VITC data. The setup of the lines for recording VITC
depends on whether the 4025TR is configured for one-line, two-line or
three-line VITC encoding.
Use the Outputs tab of the configuration screen to set the VITC line
numbers.
Selection of the lines for recording the VITC is performed using the setup
menu displayed on the character generator. Press the SETUP to access
the setup menu. Using the " & # keys drop down the TIMECODE menu.
$ & % keys to highlight the GEN VITC1 LINES or
Use
the
GEN VITC2 LINES menu item to set the VITC lines. Press the SELECT
key to show the VITC LINES sub menu. Line1 and line2 are the two lines
currently selected for the VITC1 or VITC2 generator.
When the VITC LINES sub menu is first selected, the Line1 will be in
reverse video indicating it can be changed. Press the $ & % keys to
