Garmin Reactor 40 Manual de instruções de instalação

In the location where you plan to connect the CCU,

disconnect one side of a NMEA 2000 T-connector

the network.

If necessary, connect a NMEA 2000 backbone extension

cable (not included) to the side of the disconnected T-

connector to extend the NMEA 2000 network backbone.

Add an included T‑connector for the CCU to the NMEA 2000

backbone by connecting it to the side of the disconnected

T‑connector or backbone extension cable.

Route the included drop cable

bottom of the T-connector added in step 4.

If the included drop cable is not long enough, you can use a

drop cable up to 6 m (20 ft.) long (not included).

Connect the drop cable to the CCU and the T-connector.

If needed, repeat steps 2 through 6 for the helm control

(optional) or a compatible Garmin chartplotter.

Connecting Optional NMEA 2000 Devices to the

Autopilot System

You can use advanced features of the autopilot system by

connecting optional NMEA 2000 compatible devices, such as a

wind sensor or a GPS device, to the NMEA 2000 network.

NOTE: You can connect optional devices that are not NMEA

2000 compatible to the helm control through NMEA 0183

(NMEA 0183 Connection Considerations, page

Add an additional T-connector (not included) to the NMEA

2000 network.

Connect the optional NMEA 2000 device to the T-connector

by following the instructions provided with the device.

Configuration

The autopilot must be configured and tuned to your boat

dynamics. You can use the Dockside Wizard and the Sea Trial

Wizard on the helm control or a compatible Garmin chartplotter

to configure the autopilot.

See the included configuration guide for more information on

configuring the autopilot.

Maintenance

Corrosion Blocker

To ensure the long life of all parts, apply corrosion blocker to the

drive unit at least twice yearly.

A marine-rated corrosion blocker should be applied to the drive

unit after all connections are made.

Appendix

NMEA 0183 Connection Diagrams

The helm control is not included in all autopilot packages. A

helm control must be installed in your autopilot system to

connect NMEA 0183 devices according to these diagrams. If

you install the autopilot without a helm control, all NMEA devices

you plan to use with the autopilot system must be connected to

a compatible Garmin chartplotter on the same NMEA 2000

network as the CCU. See the installation instructions provided

with your chartplotter for NMEA 0183 connection information.

These wiring diagrams are examples of different situations you

may encounter when connecting your NMEA 0183 device to the

helm control.

NMEA 0183 Connection Considerations

• The chartplotter provides one Tx (transmit) port and one Rx

(receive) port.

• Each port has 2 wires, labeled A and B according to the

NMEA 0183 convention. The corresponding A and B wires of

to the CCU and to the

8).

NOTICE

each internal port should be connected to the A (+) and B (-)

from

wires of the NMEA 0183 device.

• You can connect one NMEA 0183 device to the Rx port to

input data to this chartplotter, and you can connect up to

three NMEA 0183 devices in parallel to the Tx port to receive

data output by this chartplotter.

• See the NMEA 0183 device installation instructions to identify

the transmit (Tx) and receive (Rx) wires.

• You must use 28 AWG, shielded, twisted-pair wiring for

extended runs of wire. Solder all connections and seal them

with heat-shrink tubing.

• Do not connect the NMEA 0183 data wires from this device

to power ground.

• The power cable from the chartplotter and the NMEA 0183

devices must be connected to a common power ground.

• The internal NMEA 0183 ports and communication protocols

are configured on the chartplotter. See the NMEA 0183

section of the chartplotter owner's manual for more

information.

• See the chartplotter owner's manual for a list of the approved

NMEA 0183 sentences that the chartplotter supports.

NOTE: When connecting a NMEA 0183 device with two

transmitting and two receiving lines, you do not need to connect

the NMEA 2000 bus and the NMEA 0183 device to a common

ground.

Only One Receiving Wire

If your NMEA 0183 compatible device has only one receiving

wire (Rx), you must connect it to the blue wire (Tx/A) from the

helm control, and leave the white wire (Tx/B) from the helm

control unconnected.
