- Page 16 Course Translator DAC-109 2.3.2 Operation mode of the Product Once the power is supplied, the DAC transfers to operation mode. In this mode LCD displays 2 heading values: a) received heading value from NMEA signal source (e.g., digital gyrocompass); b) current heading value on the analog signal receivers (e.g., repeaters connected to the DAC).
- Page 17 Operating manual Frequency Choice Frequency selection of output sine wave analog signal. Frequencies to select: 50 Hz, 500 Hz. Ratio Choice Selection of ratio between ship turn and selsyn rotation of analog receiver. Ratios to set: 1:36, 1:60, 1:90, 1:180, 1:240, 1:360. Channel Select A user can select the main channel to receive heading data in digital NMEA 0183 sentences.
- Page 18 Course Translator DAC-109 Backup Channel If the data are absent on the main channel, the Product switches to the backup channel. If the backup NMEA signal source is not connected, set the parameter to «Off». Values to be selected: On, Off.

Questions and answers
Что означает ошибка Repeater type synchro
The error "Repeater type synchro" for the MSA DAC-109 likely refers to issues with the connected synchro-type repeater. Possible causes include:
- Wrong settings of reference and phase voltages of the synchro (selsyn), causing nonuniform or jerky rotation.
- Malfunctioning connections, such as loose or oxidized terminals, poor soldering, or damaged cables.
- Mechanical malfunctions in the repeater.
- Incorrect or missing initial position data for analog repeaters.
To resolve it, ensure correct voltage settings, check all connections, and verify initial position data is entered.
