To open the Main Menu press the 3-directional configuration wheel in home screen, navigate by
toggling left/right. Menus are rotational, so you can go from the first to the last setting by moving left.
Pressing the highlighted selection will open its submenu, pressing the arrow up/house symbol will take
you back again. When there is no further submenu the current active setting will be highlighted. If you
do not want to apply changes just press on the highlighted selection and you will fall back to main
menu without alterations.

Selecting the operation Mode will allow for one step configuration when initializing your Lockits for a
new project. Just pick your application and all necessary adjustments will be performed automatically
under the hood. Together with the “Full” Jam mode and auto frame rate setting there is hardly anything
left to do but choose your sync option on ACL204 if applicable and Jam sync your units via cable or ACN
after having put one unit into C-Jam Master mode. Each mode has a dedicated LED blink code of the
two colored LEDs above the OLED display, which will also show selected mode and active transmission
direction.
“
Int TC”
:
“Classic” Lockit mode, the unit will run on its internal generator with standalone accuracy of
.1ppm, ACN disabled. MIDI timecode (MTC) will be put out over USB (ACL204 and ACN-LS) or Lemo ACN
(ACN-TL).
“C-Jam”
:
Default, as
“Int TC”
but with ACN enhancement. This is the recommended setting when
running any combination of ACN ready units. The devices can be jammed and TC framerate applied
over ACN, metadata transfer with a Master Lockit in Hub mode is activated. Additionally the units will
automatically adopt their pace to a “Master” unit for unprecedented zero drift accuracy and divergence
down to 10uS.
On powering up, Lockit devices will generally start up with unset generator and thus in idling slave
mode with a red flashing LED. Then jam one (and only one) deliberate unit to time of day and enable
“Master”
in its ACN menu and you never need to worry about TC for the rest of the day as long as the
Master keeps power. This Master will be identified by a dedicated blink pattern and “M” will show up in
the lower right corner of the OLED. The other units will then jam their generators and framerate and
follow as “Slaves” indicated by “S” and an according blink code. The intelligent C-Jam algorithm will
automatically improve the accuracy and establish zero latency, zero drift lock between units within the
ACN.
With an active
“Master”
already in range
“Slaves”
will automatically re-jam after powering on or a battery
swap. As ACN broadcasts only happen every 6 seconds, it may take this long for a freshly booted
“Slave”
to pull in. If “Slaves” lose connection to a previously present “Master” they will keep their loyalty for 30
seconds and then switch over to “(S)” which means you can move over “Master” to another unit.
Note: Always make sure just one unit is set to “Master”.
