OPTIONAL SOFTWARE
4.4.3
Generator modes
The 4025TR must be configured from KeyLog TRACKER™ in order to use
the ARRI time code processing functions. Use the Codes and Outputs Tabs
of the Configuration screen to do this.
When the ARRI option is enabled, the ARRI EDGE, ARRI RDR2 +
KEYKODE, and ARRI 3 LINE VITC modes are available on the
Configuration screen.
dropdowns on the Codes tab are set to ARRI time and ARRI user bits
respectively.
The timecode is read from the 5500A using LTC1 reader. These numbers
are adjusted for the head offset (KK head offset & ARRI offset). The
compensated timecode numbers are backed up with biphase and rate
converted to the video transfer rate (in 24 frame NTSC transfers) before
being inserted into the Audio time generator. The Outputs tab determines
where the Audio time code will be output in the LTC and VITC.
An ARRI JAM control allows the Audio generator time numbers to be
updated either from the ARRI timecode or only from biphase. When the
generator numbers are being updated by biphase only, the AT symbol
beside the Audio timecode character window will be in inverse video.
When the Audio time numbers are being jammed to the ARRI timecode,
the symbol will be normal. When in one of the ARRI modes, use the JAM
key on the 4025TR front panel (in Local Mode) or the ARRI JAM button on
the KeyLog TRACKER™ toolbar to enable ARRI JAM (the JAM LED will be
ON). Press the JAM key or toolbar button again to disable ARRI JAM and
update the Audio time numbers from biphase only. (The JAM LED will
blink).
4.4.4
Additional ARRI code status displays.
The ARRI STATS information is available in the Tracker Status window.
Using the KK STATS Toolbox menu item of the 4025TR, 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 4025TR 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:
