Universal NMEA to synchro converter DAC-109 is intended for converting digital course value (heading), received in the NMEA 0183 sentences into the sychro signals required to operate analogue synchro and stepper repeaters and other devices.

In addition, the converter DAC-109 may be used as a digital repeater for displaying current course value (heading). UCB-91 remote control unit may be used for remote control of DAC-109.
