frame) for 8 hours.
The camera is equipped with an instantly charged supercapacitor
buffer that is designed to keep time between battery changes. Keep
in mind that a battery which is too low to run the camera has
enough energy to drive internal clock for hours. Get into the habit
of leaving an exhausted battery on-board the camera until you have
a fresh battery close by. The supercapacitor allows a full minute for
battery replacement before timecode is lost.
8.3 ORIGINC
PLUS
MASTERCLOCK
For the most efficient and foolproof means of working with Aaton-
Code, it is highly recommended that an Aaton device called Ori-
ginCplus is used. OriginCplus can be quickly programmed with a
production ID, full date and time of day, then initialize timecode
devices in either ASCII or SMPTE form. OriginCplus is TCXO-
controlled and will run for 150 hours with an internal 9V lithium
cell; it is designed to be left on during the shoot day and used as a
comparator to monitor timecode drift between devices.
OriginCplus can also be used as a SMPTE generator to supply accu-
rate timecode for slates and inserters, or to record timecode on one
audio channel of a non timecode audio recorder.
8.4 INITIALIZING AATONCODE IN THE
CAMERA
There are two ways in which AatonCode can be initialized in the
AATON 35-III camera. The preferred method is by means of the Ori-
ginCplus, which inputs timecode in ASCII form. It is also possible for the
camera to receive information in SMPTE from directly from a SMPTE
timecode device such as an TC audio recorder. Both methods are detailed
below.
