    6. 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.
  • Page 14 When pressing the key [F3] in the standby mode of the converter (see par. 6.1) the configuration menu appears at the display of DAC-109: Exit from this menu to the standby mode of the converter is performed by the key [F3] (the set configurations are stored).
  • Page 15 Unicont SPb Ltd Technical Documentation DAC-109 Ratio Choice Selection of the relation between the ship’s turn and the analogue receiver synchro’s turn. Available relations: 1:36, 1:60, 1:90, 1:180, 1:240, 1:360 Channel Select Selection of the main channel for receiving data about a course in the digital sentences NMEA 0183.
  • Page 16 Available values of this parameter are: 2, 3, 4, 5, 6, 7, 8, 9, 10 sec. 6.3 Alarm System Several types of warning are foreseen in the DAC-109: absence of data at the main channel, absence of data at the reserve channel, absence of data at the main and reserve channel, absence of connection to the synchro-receiver, the initial position of connected analogue repeaters are not entered (see par.6.4).
  • Page 17 Warning about Absence of Data at the Reserve Channel If the setting «Backup channel» is set in «ON», DAC-109 controls receiving of data through the reserve channel. When data at the reserve channel is missing, the mark «!» appears at the indicator in the upper line, on the right from the value of course, accepted through the main channel.

    7. DEBUG TOOLS AND DIAGNOSTIC AIDS 7.1 Imitation of Digital Gyrocompass In order to simplify the process of setting the converter and connected repeaters, DAC-109 is provided with a special mode of imitation the digital gyrocompass. In this mode the converter ignores accepted data about the course from the sources of signal NMEA 0183 and processes the values of course, entered by the user from the converter’s keyboard.
  • Page 19 The second mode which is necessary for simple debugging the connected repeaters – is the imitation of cyclical turn of the ship. In this mode DAC-109 emulates a constant turn of the ship to the right with the speed of 360°/min. Changing of course at the connected repeaters, if they are connected properly, should occur with a constant speed without jerks or wobble and without changing the rotational direction.
