I/O connector. Connect J16 pin 14 to the Parallel I/O ground on pin 6. For other models of TLC consult
the instruction manual for the location of the GPI output.
When you are using the 9025TR in the high definition mode with 24p video, you need to use the 'Dual
Sync' mode of the TLC. In order to accomplish this you need to connect three sync references to the TLC.
These sync reference signals are all available on an Evertz 7750SRG-HD Slave Sync Generator module.
Connect a 24 frames per second 'slow PAL' reference to the main TLC gen lock input, connect a 30 FPS
Vertical Drive signal to the TLS Colour Frame ID input, and connect a 6 Hz pulse to the TLC J16 Pin 7.
For simplicity in making cables to interconnect the 9025TR with the telecine, 5550 and TLC, the 6 Hz
connection should be made when you are wiring the biphase cable to the telecine. For more information
about using the TLC in dual sync mode consult DaVinci technical bulletin TLC-052, available from the
DaVinci web site. For Standard definition video operation calibrate the TLC as you normally would. For
High definition video operation calibrate the system timing using the procedure outlined in Chapter 3.
2.11. CONNECTING A CINTEL TELECINE
Two signals, (biphase tach and Film Frame pulse) must be connected from the telecine in order to
generate field accurate time code and KeyKode numbers. The location and description of these signals
depend on the model of your telecine. Sections 2.11.1 and 2.11.2 provide an overview of the Cintel
connections. Section 2.11.4 provides detailed instructions for your model of Cintel telecines. In addition to
making the physical connections to the telecine you will have to select the Biphase rate, Telecine type and
set up for any video processing delays between the output of your telecine and the input of the 9025TR
using the KeyLog TRACKER™ Telecine Setup Screen. Chapter 3 provides a procedure to verify that you
have made the necessary connections and settings for your telecine.
2.11.1. Biphase Tach from the Cintel Telecine
The 9025TR is fitted with a nine pin female 'D' connector (PARALLEL I/O) for connection to the telecine
biphase. The pin connections are shown in Table 2-1.
The BPH1 and BPH2 inputs (pins 3 & 7 respectively) should be connected to biphase quadrature tach
pulses from the telecine. These TTL level pulses usually come at a rate of 10 pulses per film frame. The
9025TR can also accommodate tach rates of 1, 2 or 5 pulses per frame. For best results use the highest
biphase rate possible.

EDGE numbers that increment and decrement when the telecine moves forward and reverse respectively.
In the event that the 9025TR counts in the reverse direction when the telecine is in forward play, reverse
the two biphase connections to the 9025TR.
To minimize the effects of cross coupling and noise on the biphase signals, which
can affect the counting reliability of the 9025TR, you should use a cable, which
provides separate shields for each phase of the biphase signal.
