* Dat recorders Must be "pulled up", in other words run at 30 fps instead of

29.97 fps. The word clock will run faster in the recording process and be

pulled down to 29.97 fps to run in sync with the Telecine which transfers the

film, which was shot at 24 fps at 23.98 fps to be in sync with NTSC colour

video at 29.97 fps.

Note 1: The use of drop frame codes in the recording process is not

recommended

Note 2: Some filmcameras have a 23.98 fps framerate. Audio recorders can then

use 29.98 fps TC. Recordings can then be synchronized with the Film (shot at

23.98 fps) without the need to pull down during the TeleCine process.

This mode has the same function as the generator-only mode with the

difference that on power-up of the master slate the RTC time and date is

loaded into the Generator.

Reader/Generator Mode

In many film situations there is a requirement for 2 timecodes to be displayed.

In the classical situation a playback with timecode is being played in a scene

where at the same time sound is being recorded.

The master slate when opened, displays the Playback timecode (ext TC)

connected by cable or transmitted by radio, thus facilitating syncing playback

to picture. When the slate is closed the generator time is displayed thus

giving a timecode value corresponding to the time on the recorded tape.

Note. When switch 7 is ON the playback time value at the moment of closure of

the slate is displayed for 2 mins after the userbits. This value can be logged by the

Continuity/Script person.

Feature: With dipswitch 12 ON the TC out signal (pin 5 LEMO) contains the

generator time and the reader time in the generator userbit slot.

This TC could be transmitted for logging purposes.

Reader Mode

In this mode the slate is a reader only and can be used in conjunction with a

radio link or cable to display Playback timecode in a videoclip or multicamera

shooting situation.

When the slate is opened the timecode is displayed.
