2.14 CONNECTING THE PARALLEL REMOTE CONTROLS
"
INSTALLATION
With the PLAY WINDOW VALUE = 00, the 4025TR will re-jam
when this condition exists. With the PLAY WINDOW VALUE =
1, the 4025TR will ignore this apparent error and continue using
the biphase based numbers, which will be correct if no splices
have occurred.
If a splice is encountered, during the transfer, the 4025TR will
re-jam to the KeyKode numbers with the possibility of a ±1
frame error.
stopped and restarted. This will zero the effect of Scantrack,
and will allow the 4025TR to jam unambiguously to the
KeyKode numbers.
The Parallel I/O connector has 4 remote control inputs to control various
generator functions. The Serial I/O connector has 5 remote control inputs
to control various character generator functions. (See Chapter 7 for a
pinout drawing of the connectors).
2.14.1 Film Gauge and Film Rate Selection
Pins 1 and 9 on the PARALLEL I/O 'D" connector may be connected to
tallies from the telecine, or to external toggle switches, to program the film
gauge and transfer rate.
Mode changes will take effect when either a timecode or film edge number is
entered from the front panel, or when the telecine has achieved a full stop
condition.

Film Rate select (pin 1)
2.14.2 Film Centering
Pin 5 on the PARALLEL I/O 'D" connector may be connected to a tally
from the telecine, or to an external toggle switches, to act as an alternate
method of telling the 4025TR that the film is centered in the gate.
Momentarily ground this input to 'centre' the 4025TR's film frame boundary
reference. See section 3.10.9 for a full description of centering.
