INSTRUCTION MANUAL 1 INTRODUCTION The DR76 Digital Repeater, the AR78/AR80 Analog repeaters, and AR81/AR83 Bearing repeaters have been designed to accept a variety of digital inputs that are sensed when first switching on the repeater. The repeaters accept serial data (RS422). The D-type connector has pins allocated for power and serial data. The serial input is configured to recognize NMEA 0183 HDT, HDG and HDM sentence structures in priority order.

INSTRUCTION MANUAL 2.3 Cable connection Caution Any voltage supplies other than those specified in the product specification, page 2, may cause damage to the repeater. The repeaters have no power switch, and the repeater will be automatically started when the cable is connected to the unit. It is therefore recommended to connect the cable via an external power switch. The repeaters are designed to run on 24VDC, and accept a digital RS422 data signal. The repeater is supplied with a 2.
Simrad DR76, AR78, AR80, AR81 and AR83 Repeaters 2.4 Operation TURN INDICATOR TRUE DIM BAR DIM SET DIGIT HEADING SIMRAD DR76 The DR76 front panel includes the following elements: • Horizontal Turn indicator TURN INDICATOR - used either as a rate of turn indicator, or as a steering indicator to indicate the difference between actual and set course TRUE • Heading display - showing the input heading received from the transmitting device, e.g.
INSTRUCTION MANUAL If the signal is invalid or missing after 1 second, this will be indicated with flashing heading display. When the defined input signal is lost, power must be switched off and on again. If the cable not is connected via an external switch, the cable must be disconnecting and reconnected again to define a new input signal. Adjusting display illumination The display illumination on both displays may be adjusted by using the dimmer buttons.
Simrad DR76, AR78, AR80, AR81 and AR83 Repeaters Setting the Display mode DIM BAR SET Active mode is selected by pressing the SET button and the DIM BAR button simultaneously. The last digit in the heading display will now cycle between the three display modes. Then selected mode is indicated, this mode is activated by releasing both buttons. 2.

Optional bracket mounting Numbers in brackets refer to the drawing below.
INSTRUCTION MANUAL 3.3 Cable connection Caution Any voltage supplies other than those specified in the product specification, page 9, may cause damage to the repeater. The repeaters have no power switch, and the repeater will be automatically started when the cable is connected to the unit. It is therefore recommended to connect the cable via an external power switch. The repeaters are designed to run on 24VDC, and accept a digital RS422 data signal. The repeater is supplied with a 2.
Simrad DR76, AR78, AR80, AR81 and AR83 Repeaters 3.4 Operation DIM SIMRAD AR 80 The analog repeaters include a rotating dial and a dimmer button. Turning the repeater ON The repeaters have no separate power button, and the unit is automatically turned on when the cable is connected to the unit. The repeaters have been designed to accept a variety of NMEA input sentences. When the cable is connected to the repeater, it will automatically sense which sentence that is present.
INSTRUCTION MANUAL 3.5 Commissioning Perform the following tests when commissioning the repeater: 7 Ensure that the mechanical installation and cable connection has been completed according to the description on previous pages 8 Connect the cable to the repeater. The repeater will automatically sense which digital signal that is present - The repeater will align itself to zero and then to the transmitted gyro heading 9 3.6 Ensure that the lighting is set to a suitable level.

Simrad DR76, AR78, AR80, AR81 and AR83 Repeaters ICIF board F3 F2 F4 F1 F5 F8 TB2 TB3 When an AR81/83 is connected to a GC80/85 Compact gyro system, the serial output signal from the gyro has to be set to IEC-61162-1 ed.2. This is done by setting a jumper on the ICIF board in the GC80/85 Compact Control unit.
INSTRUCTION MANUAL Connecting an AR81/83 repeater to a GC80/85 Expanded/Dual gyro system 10 TX channels are available when connecting the AR81/83 repeater to a GC80/85 Expanded or Dual gyro system.
Simrad DR76, AR78, AR80, AR81 and AR83 Repeaters When an AR81/83 is connected to a GC80/85 Expanded or Dual gyro system, the serial output signal from the gyro has to be set to IEC-61162-1 ed.2. This is done by setting a jumper on the SCC or SIFC board in the GC80/85 Expanded, or on the SCC or SCOIF board in the Dual control unit. Depending on which TX port that is used for connecting the repeater, the jumpers have to be set as described in the following pages.
