6.1 Factory Settings
At first delivery or having carried out the function FACTORY RESET the standard unit will have
the following settings:
Basically all is set to zero or switched off, except:
Frame rate 25
LTC output level 1.5 V
pp
VITC parameters Lines 18 and 20
Genlock mode Video/black-burst
User mode 1 = TTT, i.e. the multiplexed data of the LTC(MTD)
Display Time
Key lock Off
LTC generator operating mode time operating mode
All settings of the menu will be as in the examples shown in chapter “Detailed Menu
Description”.
With these parameters GM-TTT operates in the time operating mode and is ready to receive
the CET/CEST from the reference clock. Automatic pre-set of the internal clock is programmed
to occur after power on (after factory reset as well) and once each day at 3 o’ clock with
respect to the reference time. The time zone parameters of the internal clock gets a pre-set in
a way, that CET/CEST will be generated. The binary groups contain the multiplexed data of
the LTC(MTD), so the unit is ready to operate with the MTD Time-Timer-Time Code System.
This feature is kept during all the time, timer, tc and start operating modes, especially the tc
operating mode is programmed to transfer only time values with an offset equal to zero.
All settings of GM-TTT as well as those of the MTD system - i.e. settings made via any
operational units -, are saved in a non-volatile memory. The data and parameters concerning
the MTD system and their factory setting are listed in the table below:
