turned off. In the ARRI RDR2 + KEYKODE mode, the timecode from the
Film Ident system is placed in the generator time bits and the time data
from RDR2 (The VITC reader) are placed into the user bits of the LTC and
primary VITC, and the Full Keykode is placed in the secondary VITC.
Insertion of the ARRI timecode into the generator time is identical in both
modes.
The timecode is read from the Film Ident systems using RDR1 (assigned to
the LTC reader). These numbers are adjusted for the head offset (KK
head offset & ARRI offset).
backed up with bi-phase and rate converted to the video transfer rate ( in
24 frame NTSC transfers) before being inserted into the time bits of the
generator.
An ARRI JAM control permits the generator time numbers to be updated
either from the Film timecode or only from bi-phase. When the generator
numbers are being updated by bi-phase only, the GT symbol beside the
generator timecode character window will be in inverse video. When the
generator numbers are being jammed to the ARRI timecode, the symbol
will be normal. When in one of the ARRI modes, press the JAM key to
enable ARRI JAM ( the JAM LED will be ON). Press the JAM key again to
disable ARRI JAM and update the generator time numbers from bi-phase
only. (the JAM LED will blink). Note that the GEN ASSIGN will still be set
to one of the ARRI modes even though the time numbers are being
updated by bi-phase only.

4.1.4. Additional ARRI code status displays.

Using the KK STATS Toolbox menu item of the 4025, the KeyKode status
display can be enabled. To accomplish this press SHIFT + FORMAT,
select the DEBUG drop down menu and the KK STATS item. Turn KK
STATS ON. When the 4025 is operating in one of the ARRI modes, the KK
STATS will contain an additional line, known as the ARRI STATS, which is
necessary to determine the accuracy of the installation. The ARRI STATS
contains the following information:
APERF: 1 AERR 00
APERF is an internal register used in the ARRI timecode offset
calculations.
AERR is the whole frame error between the bi-phase based Film timecode
numbers, and the numbers being read from the Film Ident system.
ASFERR is the partial frame error between the bi-phase based Film
timecode numbers, and the numbers being read from the Film Ident
system.
AJ1 Is an optional display that occurs when the bi-phase based
numbers re-jam to the numbers being read.
AJ1 means that differences in the time numbers caused the re-
jam
