Synchronization
After power up, all 4 inputs LEDs will flash yellow as long as the TBox is not synchronized.
There are four different methods to synchronize the TBox.
a)
Sync at Zero.
This is the default synchro method. Once the TBox is switched ON, the first impulse will
sync the internal time at Zero
b)
GPS Sync (models 20 & 21)
To start the GPS Sync, ensure TBox is powered off, hold down the button “Input 1” whilst
powering ON the TBox
The sync will commence once the TBox receives sufficient GPS data
Once synchronized, the internal clock drift is constantly compensated by GPS signals (as
long as GPS coverage is maintain)
c)
External.
Not yet implemented.
d)
Sync via app
All synchro methods presented above can be controlled manually or automatically by
our Timing Applications
It is also possible to synchronize the TBox to a user define time of day, using one of the 2
inputs
8.
Bluetooth
A Bluetooth connection can be established with compatible FDS timing or setup Apps.
After power up, the TBox advertises its presence for 2 minutes. During this period the box can be
detected and connected by the user App. To re-establish detection after the 2 minute period
simply momentarily press the power button to reactivate the Bluetooth advertising process.
