TBox-1x & TBox-2x User manual
8. Synchronization
There are four different methods to synchronize the TBox.
After power up, all 4 inputs LEDs will flash yellow as long as the TBox is not synchronized.
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
• Only possible with models including GPS (TBox-2x)
• 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 4 inputs
9. 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.
