OPERATION
The newer barcoded film stocks use a consistent numbering system
consisting of a film manufacturer's letter, an emulsion letter, a six digit
prefix and a four digit key number. When using KeyKoded film stock, the
4025TR should be set for the 4 DIG FT + FRM format.
If you are operating the 4025TR in one of the 3-line modes the maximum
footage is set to 9999.

3.10.9 Centering the 4025TR's Framing Reference

For the 4025TR Film Footage Encoder to detect where the film frame
boundaries are (with respect to the biphase pulses and the barcode
numbers), it is necessary to properly calibrate the 4025TR's framing.
The following procedure must be used to calibrate the 4025TR's framing
reference each time a new film is loaded on the telecine, or when the telecine
framing changes due to splices, panning or zooming, etc.
After you stop the telecine with the film properly framed in the gate use one
of the following methods of centering.
1. Enter a new film edge number using the front panel when the
film is properly still framed in the gate. If you are using a Film
Barcode reader you may set the edge numbers to 0000+00, as
they will be updated from the barcode reader when the telecine
is at Play speed.
selecting the KK JAM mode.)
2. Pin 5 on the parallel I/O connector on the 4025TR rear panel
may be used as a centering input. Momentarily close this input
to ground and release it when the film is properly still framed in
the gate.
3. When you are controlling the 4025TR from the KeyLog
TRACKER™ software use the LOAD FILM button on the
TRACKER toolbar.
When the 4025TR is properly framed, the SCAN value in the KeyKode Status
information should be at or near zero, each time the telecine is put into
PLAY. ( Cintel telecines only)
