OPERATION
Model 5550 Universal Film Data Decoder Manual
3.2.6. Controlling the Intensity of the Time Code Light Source
The model 5550 controls the brightness of the time code light source in
order to accommodate for the various exposure densities of the time code
on the film.
The light source intensity control can be either manually
controlled by the user or automatically controlled by the 5550. There are
two menu items that are used to control the LED intensity.
tc intensity
Is used to display/set the intensity of the light source.
Normally you will require a higher intensity for darker exposures,
and a lower intensity for lighter exposures. The value shown
ranges from a lower limit (below which the sensor will not detect
anything) and 999. When you are in the automatic time code
intensity mode, this menu item will show the current value of the
time code light intensity.
tc intens Is used to select whether you want to set the timecode light
source intensity manually or have the 5550 use its automatic
intensity mode.
Select man to adjust the intensity manually.
Select auto for the normal automatic mode. In this mode the
5550 is constantly adjusting the time code light intensity to
achieve optimal reading.
3.3.1. Setting the correct Biphase Rate
The ! and "keys select which biphase frame rate (in cycles
biph
per frame) will be used for the biphase inputs. This setting must
be correct for the KeyKode Hunt and auto time code intensity
routines to work correctly. The supported biphase rates are 1/2,
1, 2, 5 and 10 pulses per frame. (See section 2.3.3 for more
information regarding connecting the biphase inputs).
3.3.2. Adjusting the Front Panel Display Brightness
The DISPLAY LEVEL menu item is used to adjust brightness of the front
panel display. Use the ! and "keys to adjust.
3.3.3. Setting the KeyKode Validation Beep
kk beep
Selects whether the 5550 will sound a beep each time it reads a
valid keykode number.
