turned ON, ( a special window appears at the top of the screen
which indicates that you are in RAM VIEW - ENTRY MODE.
See section 3.8.2 for a complete description of RAM VIEW

NOVRAM DEBUG
(NOVRAM) diagnostic display will be shown in the character
inserter. This display is used to aid in troubleshooting problems
in the field and is not used during normal operation or
maintenance procedures.
Proceeding with the NOVRAM VIEW will allow the user configured
parameters including KeyKode head offsets, horizontal char size, user
configurations, etc. to be overwritten. PROCEED WITH CAUTION!!!
The 4025 Film Footage Encoder contains a multi-line vertical interval
(VITC) and a linear (LTC) time code generator.
generator follows the LTC generator, except that it is updated at the field
rate instead of the frame rate. The secondary VITC generator is used to
encode the full KeyKode edge number including frames in certain modes.
The 4025 also supports encoding the data in VITC according to the 3 Line
VITC Evertz has developed with other manufacturers. Both the VITC 2 line
of the two line format and the second and third line of the three line format
have special encoding applied such that they require a special Evertz
reader such as the Afterburner to decode the data. With this special
encoding applied, conventional readers will not become confused by the
special film numbering systems required to encode the data. Figure 0-10
shows the various ways that the 4025 will encode time and KeyKode
numbers, showing what data is placed in each set of VITC lines. Figure 3-
11 shows how the data is encoded in the 3 Line standard.
