1 I NTRODUCTI ON

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 onthe repeater.

The repeaters accept serial data (RS422). The D-type connectorhas 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.

All repeaters may be delivered with an optional mountingbracket.

The repeaters should be mounted where it is most convenient forthe user, with regard to the units environmental protection,temperature range and cable length. The unit should not beinstalled in area exposed to heavy vibrations.

Avoid mounting the repeater where it is easily exposed tosunlight, as this will shorten the lifetime of the display.

2 .3 Cable conn ect io n

Caut ion Any voltage supplies other than those specified in the productspecification, page 2, may cause damage to the repeater.

The repeaters have no power switch, and the repeater will beautomatically started when the cable is connected to the unit. Itis therefore recommended to connect the cable via an externalpower switch.

The repeaters are designed to run on 24VDC, and accept adigital RS422 data signal.

The repeater is supplied with a 2.5 meters cable with a 15 pinsfemale D-type connector.

The DR76 front panel includes the following elements:

TURN INDICATOR Horizontal Turn indicator

- used either as a rate of turn indicator, or as asteering indicator to indicate the differencebetween actual and set course

HEADING

TRUE

Heading display

- showing the input heading received from thetransmitting device, e.g. the Gyro compass

DIMBAR

Dimmer buttons

- used for adjusting the illumination on the turnindicator or the back light intensity for theheading display

SET

SET button

- used for setting a course to steer, and for settingthe display mode for the turn indicator

Turn in g th e DR76 ON

DR76 has no separate power button, and the unit isautomatically turned on when the cable is connected to the unit.

The repeater has been designed to accept a variety of NMEAinput sentences. When the cable is connected to the repeater, itwill automatically sense which sentence that is present. Thefollowing priority is used when defining the signal:

- True heading (HDT)

- Heading & Variation format (HDG)- Old Heading format (HDM)


13/40

INSTRUCTION MANUAL

20221487 / B 7

If the signal is invalid or missing after 1 second, this will beindicated with flashing heading display.

When the defined input signal is lost, power must be switchedoff and on again. If the cable not is connected via an externalswitch, the cable must be disconnecting and reconnected againto define a new input signal.

Ad jus t i ng d i sp lay i ll um ina t i on

The display illumination on both displays may be adjusted byusing the dimmer buttons.

Heading display.When a dimmer buttons is pressed, the illumination will beincreased/decreased until the button is released.

Disp lay m odes fo r Tu rn i nd i cato r

DR76s Turn indicator may be set to 3 different display modes,defined as Mode 0, 1 and 2.

Mode 0:

Rate of turn indicator with fine resolution. For each 1/10

the vessels bow turns, three bargraphs will move to left orright on the indicator.

TURN INDICATOR

Mode 1:

As for Mode 0, but with the bargraphs indicating each 1turn.

Mode 2:

In this mode the Turn indicator acts as a set steeringdisplay. When the vessels heading is identical to setcourse, all LEDs are unlit. For each degree steered off-course, one LED will be lit.

Active mode is selected by pressing the SET button and the DIMBAR button simultaneously.

The last digit in the heading display will now cycle between thethree display modes. Then selected mode is indicated, this modeis activated by releasing both buttons.

2 .5 Commiss ion ing

Perform the following tests when commissioning the repeater:1 Ensure that the mechanical installation and cable

connection has been completed according to thedescription on previous pages

2 Connect the cable to the repeater. The repeater willautomatically sense which digital signal that is present

- The repeater will align itself to zero and then to thetransmitted gyro heading

3 Ensure that the lighting is set to a suitable level. Adjust if

necessary with the dimmer button

2 .6 Fau l t f i nd ing

The DR76 is a sealed unit, and breakage of the security seal willinvalidate the warranty.

If trouble is encountered, make preliminary checks as describedbelow. If the problems remain unsolved, contact your nearestSimrad dealer for assistance.

Symptom Probable fault Remedy

The repeater does notoperate.

No power or incorrect powerconnection.

Check incoming powersupply.

The repeater aligns itselfto zero and does notrespond to headinginput.

The digital signal to the repeater iseither not present, or the sentencebeing sent is incorrect or has wrongpolarity.

Switch the unit off and onagain.

When an AR81/83 is connected to a GC80/85 Expanded or Dualgyro system, the serial output signal from the gyro has to be setto IEC-61162-1 ed.2. This is done by setting a jumper on theSCC 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 therepeater, the jumpers have to be set as described in the followingpages.

4 .4 Opera t ion

Turn ing t he repea te r ON

DI MMER POWER

The repeater holders and the repeater stand have a power buttonon the connection box.

When the cables are connected and the jumper set in the controlunit according to the previous pages, the repeater is turned on byswitching the power button.

If the signal is invalid or missing after 1 second, the repeater willindicate this by rotating the dial back and forth +/-35 around thelast known heading.

When the defined input signal is lost, the power must be

switched off and on again. If the cable not is connected via anexternal switch, the cable must be disconnecting andreconnected again to define a new input signal.

Ad jus t in g d i sp lay i l l um ina t ion

The rotary button is used for adjusting the illumination onAR81/83 repeater. Rotating the button in clockwise directionwill increase the light intensity, while the light intensity will bedecreased when the button is turned counter-clockwise.


Perform the following tests when commissioning the repeater:

1 Ensure that the mechanical installation and cableconnection has been completed according to thedescription on previous pages

2 Turn the repeater on.


3 Ensure that the lighting is set to a suitable level. Adjust ifnecessary with the dimmer button

The AR81/83 are sealed units, and breakage of the security sealwill invalidate the warranty.






The repeater aligns itselfto zero and does notrespond to heading

input.

The digital signal to the repeater iseither not present, or the sentencebeing sent is incorrect or has wrong

polarity.


Check the sentence from theheading sensor.
