This is done using a NMEA 0183 serial digital communication link, which is an established industry standard. Because of this, instruments from other manufacturers may be interfaced to the Dataline-X System - assuming that they have a NMEA output or input. This User Guide describes the Navigation System Repeater digital display, known as Dataline-X COMPASS, used within the Dataline-X System. [. . . ] For instance, the lighting level can be independently controlled for: 1. This is independent of the display colour, so that displays in the same bank may have different colours if desired. Press both buttons together, and hold for more than 3 seconds, until 'rEd', 'Grn', or 'YEL' is shown on the display. Press the LOCK button once until the LCD indicates '-1-' (or '-2-'). Select the required lighting bank, either 1 or 2, by pressing both buttons together. Return to the main display by pressing the HEADING button twice to select the Calibration Mode End Screen, and then pressing both buttons together. 4. 5 LCD Contrast Setting The LCD on Dataline-X Series instruments can be set to one of two or more contrast levels to best suit the viewing angle of the particular installation. The default level (level 2) is suitable for a wide range of viewing angles and will probably not require alteration. However, if viewing the display from above, the contrast level may be lowered to level 1 to reduce the 'ghosting' of the parts of the display which are turned off. The lighting is illuminated when setting the contrast to highlight the display. Press both buttons together, and hold for more than 3 seconds, until 'rEd', 'Grn', or 'YEL' is shown on the display. Press both buttons together, and hold for more than 3 seconds, until 'rEd', 'Grn', or 'YEL' is shown on the display. Press the HEADING push-button four times until the LCD shows 'HdG' and a number or letter. The number or letter indicates the status of the heading sensor, as below: 'HdG0' = 'HdGc' = 'HdG4' = 'HdG6' = Heading sensor is Not Deviation Compensated. If any other number is seen then this is another error, so consult your dealer for advice. If the LCD shows 'HdGc' then the heading sensor is already compensated. However if it needs to be compensated again due to movement of metal or magnetic objects in its vicinity then press both buttons. The LCD will show 'Hdg', and then after a short time it Page 27 Setting-Up Part 4 should show 'HdG0' to indicate that the sensor is no longer compensated and is ready to be compensated again. 5. If the LCD shows 'HdG0' then it is not compensated, and is ready to be compensated, so continue with the steps below: a. Place the vessel in a position where it can be swung through a full 360 degrees. The LCD will show 'HdG ', and then after a short time it should change to 'HdGi' to show that the process has been initiated. The rate of rotation is not critical, but about one minute per revolution is suitable. [. . . ] not aligned RFC250 Sensor: Loosen the fixings and rotate the sensor so that the arrow is facing directly forwards. Dataline Sensor: Check that the sensor is mounted on a bulkhead that faces exactly forwards. Other Sensor: Consult the manufacturers instructions. Page 37 Fault Finding Some or all headings are incorrect, by different amounts. Heading sensor not deviation compensated. Magnetic or ferrous objects moved into or away from the vicinity of the heading sensor. Part 5 Note: When checking a Compass ensure that the check is against a deviated magnetic card compass, or against magnetic bearings, or against a good hand held compass held well away from any magnetic or ferrous objects. Check for possible objects that may affect the sensor, e. g. [. . . ]
