PRINCIPLE OF CONVERTER OPERATION
6.1
Standby Mode of the Converter
Right after power-up the converter DAC-109 switches to the standby mode. Two course values are
displayed at the display in this mode:
1.
Accepted value of course from the NMEA source (e.g. digital gyrocompass)
2.
Current value of course at the receivers of analogue signal (for example, at the repeaters
connected to DAC-109).
In this mode, the internal display of the converter looks as follows:
The necessity to display two values of course is caused by the inertia of synchro receivers (see
par.6.5).
In the standby mode the user may enter into the configuration menu of the converter – in order to do
it, it is necessary to press the key [F3].
Attention! After switching on the converter it is obligatory to enter initial positions of connected
analogue repeaters (see par. 6.4).
