GEN MENU
In the GENenrator menu, you can edit the jam
mode, edit the time and set an offset of the time
code output against the jammed time.
GEN > Ja TC
In the JamTC settings, you can select from
different jam behaviors:
Navigate toggling left/right, push to select.
“AUTO” – the ACL 204 will behave as used to from the former Lockit boxes. It will jam once
time code is detected, but not re-jam while time code is continuously present. As long as
time code is present, the “I” mark disappears to indicate that the unit is not ready to re-jam.
If the time code is disconnected for 3 or more seconds, the “I” reappears to indicate that the
unit will jam again once time code is received.
“OFF” – the ACL 204 does not jam to external time ode. This setting is useful if you set the
unit manually or via ACN and want to transmit an incoming time code value (for instance
from a device in record-run mode) at record start to the ACN Master unit.
“manual/once” – the ACL 204 jams once to external time code, but then will not jam again
but close the jam port. Once jammed, the “I” indicator disappears, signaling that the unit can
not be jammed from outside. This setting is useful if you want the unit to be jammed from
external time code but then not to be changed by incoming signal anymore, to transmit an
incoming time code value (for instance from a device in record-run mode) at record start to
the ACN Master unit. Also can be used should a Lockit box be used to re-jam cameras in
intervals and using a bi-directional time code cable, which would, with some cameras that
put out time code permanently even in “ext. TC” mode like the Alexa, lead to resetting the
ACL 204 in “AUTO” mode. To reactivate the jam port, just push the config switch repeatedly
going >GEN>JamTC>manual/once> and exit. The “I” indicator appears again, the unit is ready
to be jammed once again.
CAUTION! Resetting the generator will restart the video or audio sync signal, doing this
while recording will result in a corrupted file.

SYNC>AUDIO
Pushing the config switch while AUDIO is
highlighted takes you to the audio sync settings.
The curser is on the signal type selection. Change
by toggling left/right.
Select by pushing the config switch.
Types available: Wordclock, Black Audio (AES3)
Pushing the config switch selects and takes you to the rates setting.
Sample rates available: 32 KHz, 44.1 KHz, 48 KHz, 88.2 KHz, 96 KHz, 176.4 KHz, 192 KHz and
their respective pull-up / pull-down rates.
SYNC>OFF
The FPGA chip is powered off, no sync signal is
generated. Use this in time code only applications
to save battery life. You will be asked to confirm
by navigating the curser to “new”.
TC MENU
Enter the TC menu to adjust the time code frame
rate.
Adjust by toggling the config switch left/right,
push in to select new frame rate:
Rates: 23.976, 24, 25, 29.97, 30, 29.97D, 30D fps
(D = drop fra e)
If settings are changed, confirmation is required:
Pushing the config switch while “old” is
highlighted, discards the changes and returnsto
the main menu.
Pushing the config switch while “new” is
highlighted will set the time code signal to the selected rate.
