Philips Quadra - evertz 9025TR Series Instruction Manual

The SOF pulse is a 'square wave' signal that goes high for 2 fields and then low for 3 fields (or vice versa)
when running at 24 frames per second (in 1080p/24). The SOF pulse will be a square wave that is high
for 2 fields and low for two fields in 25 frames per second transfers in 1080i/50 and 30 frames per second
transfers in 1080i/60. This signal should always change level around VSYNC time. The SOF pulse is not
present when the telecine is in STOP. Connect the SOF pulse to pin 2 of the 9 pin PARALLEL I/O
connector.
Connection of a Film frame pulse is required even with 1:1 video transfers in 1080i,
525i and 625i to permit the 9025TR to distinguish the difference between the field 1
and field 2 dominant pull downs.
Do NOT connect the SOF pulse to the "FRAME PULSE IN" BNC on the 9025TR.
Selecting the correct telecine type in the KeyLog TRACKER™ telecine Setup screen also selects the
FRID frame pulse handling method. The film frame pulse is sampled once per video field approximately
mid-field.

2.13.3. Philips QUADRA

The biphase tach pulse is available on the 9 pin D Sepmag connector on the telecine. Connect pins 1 and
5 from this connector to pins 3 and 7 of the 9 pin parallel I/O connector of the 9025TR. Connect ground
(pin 7 on the telecine connector) to pin 6 on the 9025TR connector. Note that the pulse output should be
set to 10 pulses per film frame by proper selection of the jumper on the sprocket Pulse card in the telecine
(FY806 or FM735 card).
The FRID pulse is available on pin 17 of the 25 pin External 2 D connector on the telecine. This pulse
should be connected to pin 2 of the Parallel I/O connector of the 9025TR. Ground for the FRID pulse on
pin 18 of the External 2 connector should be connected to pin 6 of the 9025TR Parallel I/O connector.
Connect the PRESTOP signal (Pin 3 on the WETGATE connector of the Quadra) to pin 4 of the 9025TR
Parallel I/O connector. The complete cable harness required for the Quadra is shown in Figure 2-18.
