Start OriginC
by pressing the [#] key.
Enter
all of
the Prod ID digits, Date and
Time. Press [#] to scan through the
display. All fields being set, press [*] to
start the clock. To shut-down, press [#]
for five seconds until ‘
Stopped
’ appears.
To ASCII initialize
Cantar, cameras
or other machines with ASCII (an fps
agnostic protocol), plug the
Lemo 5 into the LTC socket
of the machine, press [#].
OriginC’s answer back
should be '
good 00.0
'.
To ASCII check
if a camera
clock is within drift limits,
connect it to OriginC once in a while,
press [#]. OriginC displays ‘
good
’
‘
fair
’ ‘
bad
’ or ‘
diff-time
’, followed by the
amount of drift in frame tenths.
To LTC init
a machine with SMPTE LTC,
simultaneously press [#] [0].
To get or check LTC
generated by a IVS-
TC, Fostex PD6, etc. or to simply read
external timecode, press [*] [2].
To send continuous LTC
to a non-
TC recorder, press [*] [1], OriginC
generates a SMPTE LTC signal to be
recorded on an unused audio track.
To select 24, 25, 30fps
SMPTE LTC out,
press [*] [4], then [#] to confirm.

Companions "OriginC & GMT"
GMT
is a 1 ppm low-power LTC
generator for SD or HD cameras,
audio recorders and digi-slates.
•
GMT
is momentarily initialized from
an ASCII master-clock or another
LTC source, whatever its normalized
frame-rate.
Permanently installed on a video camera,
its (internally adjustable) line-level LTC-out is
recorded on an audio track of the camera;
this bonds the record-run Video-TC of the
camera to the free-run Audio-TC which is
also running in the other machines on the
set. During image digitization, the NLE
will read the Audio-TC and «autosync»
images and BWF audio by this common
TC. As opposed to Video-
TC radio transmission from
camera to recorder, this
method works for multicamera
shoots.

emergency master-clock.
Turn it ‘On’ then press the
[white] button to initialize
its clock from hour 01. The
date generated by a new GMT starts at
Y92/M01/D01, it is incremented by
one day at each power ‘On’ followed
by a [white] button initialization. The
“Year/Month/Day” is stored in a non-
volatile memory, resulting in a
never-
twice-the-same date
from a given GMT.
GMT-u (NEW MODEL) remote record
• Whatever the initialization mode,
pressing the GMT-u [white] button
for more than three seconds makes
the LTC output freeze on the last TC
value (the four frame-rate LEDs blink).
A short push on the [white] button
unfreezes the LTC. Sent by wire or
radio, this signal stops and starts the
Cantar recording (p.19).
