Synchronization
There are 5 different methods to synchronize the TBox-Radio.
All manual input LEDs will flash yellow until a synchro is completed.
a)
Sync at Zero
This is the default synchro method for
TBox-40
. Once the TBox-Radio is switched ON, the
first impulse will sync the internal time at Zero
b)
Internal Sync (TBox-41 only)
This is the default synchro method for
TBox-41
. Once the TBox-Radio is switched ON, it is
synchronized with the internal RTC. RTC value is updated during a GPS or App Sync
c)
GPS Sync
To start the GPS Sync, ensure TBox-Radio is powered off, hold down the switch “Input 1”
while powering ON the TBox-Radio. Our PC or IOS setup application can also be used to
start the Synchro.
The sync will commence once the TBox-Radio receives sufficient GPS data
Once synchronized, the internal clock drift is constantly compensated by GPS signals (as
long as GPS coverage is maintained)
d)
Manual
A user defined time of day is sent via Bluetooth or via a com port. The synchro is started
using one of the 2 inputs or a radio impulse.
e)
External
External synchro uses the auxiliary 7 pins connector as the source of synchro. First a time
stamp has to be received on the aux RS232 port followed by the top synchro signal.
This can be used to keep a perfect synchronization between two TBox (using a dedicated
cable). The Master TBox can be first synchronized using any other mode, then external
synchro is selected on the slave TBox.
External synchro can be selected manually by pressing the switch “Input 2” while
powering the TBox.
f)
Sync via app
All synchro methods presented above can be controlled manually or automatically by
our Timing Applications
