PURPOSE
The digital-analogue converter DAC-109 is intended for converting a digital value of course, which is
received in the sentence NMEA, into the synchro or step signals which are necessary for controlling
analogue repeaters and other devices based on synchro or step repeaters.
In addition, the converter DAC-109 may be used as a digital repeater for displaying a current value of
course.
