Installation Manual 5 OPTIONAL EQUIPMENT 5.1 DR75 Digital Repeater (NMEA) Introduction DR75 is a four digit, digital heading repeater. It is powered from 24 VDC, which is derived from the ships supply. Power consumption is low typically 10 watts. The display gives a resolution and an accuracy to one tenth of a degree. The display is visible to three meters over an arc of ninety degrees from its centre. The repeater can either be console mounted or bulkhead mounted with its supplied trunnion bracket.
Robertson RGC12 Gyro Compass Operational Features Dynamic performance: The Display has a resolution of one tenth of a degree and will retain alignment for rates in excess of 12 degrees per second. Environmental specifications Splash proof to: ............................................................................ IP33 Temperature:.................................................................-15°C to 45°C Humidity:..............................................................
Installation Manual Electrical Installation Caution ! Application of any voltage supplies other than those stipulated in the product specification may cause damage to the repeater. DR75 are connected to the ships cabling by a supplied prewired D-type connector and a 2.5 m (8’) six core screened cable. The D-type connector plugs directly into the repeater to make maintenance and servicing easier. The cable is connected to the Ship’s Data Cable.
Robertson RGC12 Gyro Compass Figure 5-2 DR75 Digital Repeater - Dimensions (Drw. N4-710311B) Controls The DR75 has three button controls. The first two are used to Dim the horizontal LED bar graph display and control the back lighting to the LCD display. The third switch is used to mark or ‘SET’ a course that is to be steered to. This is depressed when the desired heading to be steered to is reached. When the correct course is being steered all the indicators are unlit.
Installation Manual Indicators The DR75 has two indicators. One is a four digit liquid crystal display which displays input heading received from the transmitting device e.g. Gyro. The second is a horizontal LED bar graph display that is used either as a rate of turn indictor or as a steering indicator to show how far of a set course the vessel is. Modes The repeater’s LED bar graph display has three modes of operation.
Robertson RGC12 Gyro Compass 5.2 RSR68 Steering Repeater (Step) Introduction The RSR steering repeater satisfy a number of applications where accurate repetition of ships heading is displayed for pilotage or navigation purpose. The display consists of an electro-mechanically driven compass card graduated in degrees. A lubber line is provided at the 000 degree mark Interface between the display and the ships system is through a cable, which may be terminated via a suitable junction box.
Installation Manual Dynamic limits: Alignment is retained with heading change rates of up to 12 degrees per second. Performance accuracy: Indicates the transmitted heading in 1 degree scale graduations in steps of 1/6 degree resolution.
