Garmin REACTOR 40 COMPACT HYDRAULIC Installation Instructions Manual - page 7
NOTICE
If you are connecting this device to an existing NMEA 2000
network, the NMEA 2000 network should already be connected
to power. Do not connect the NMEA 2000 power cable to an
existing NMEA 2000 network, because only one power source
should be connected to a NMEA 2000 network.
If you are connecting this device to an existing NMEA 2000
network or engine network by another manufacturer, you should
install a NMEA 2000 Power Isolator (010-11580-00) between
the existing network and the Garmin devices.
You can connect the CCU and the optional helm control through
an existing NMEA 2000 network. If you do not have an existing
NMEA 2000 network on your boat, all the parts needed to build
one are supplied in the autopilot package (
NMEA 2000 Network for the Autopilot System
).
To use the advanced features of the autopilot, optional NMEA
2000 devices, such as a GPS device, can be connected to the
NMEA 2000 network.
If you are unfamiliar with NMEA 2000, you should read the
“NMEA 2000 Network Fundamentals” chapter of the
Technical
Reference for NMEA 2000 Products
. To download this
document, select Manuals on the product page for your device

Building a Basic NMEA 2000 Network for the Autopilot
System
NOTICE
If you are installing a NMEA 2000 power cable, you must
connect it to the boat ignition switch or through another in-line
switch. NMEA 2000 devices will drain your battery if the NMEA
2000 power cable is connected to the battery directly.
A dedicated helm control is not included in all autopilot
packages. If you install the autopilot without a dedicated helm
control, the autopilot CCU must be connected to the same
NMEA 2000 network as a compatible Garmin chartplotter to
configure and control the autopilot system.
1
Connect the three T-connectors
À
together side-by-side.
2
Connect the included NMEA 2000 power cable
Á
to a 9 to
12 Vdc power source
through a switch
Ã
.
You should connect the power cable to the ignition switch of
the boat if possible, or route it through an inline switch (not
included).
NOTE:
The braided drain wire (bare) on the NMEA 2000
power cable must be connected to the same ground as the
black wire on the NMEA 2000 power cable.
3
Connect the NMEA 2000 power cable to one of the T-
connectors.
4
Connect one of the included NMEA 2000 drop cables
Ä
to
one of the T-connectors and to the helm control (optional) or
to a compatible Garmin chartplotter
Å
.
5
Connect the other included NMEA 2000 drop cable to the
other T-connector and to the CCU
Æ
.
6
Connect the male and female terminators
Ç
to each end of
the combined T-connectors.
Connecting the Autopilot Components to an Existing NMEA
2000 Network
A dedicated helm control is not included in all autopilot
packages. If you install the autopilot without a dedicated helm
control, the autopilot CCU must be connected to the same
NMEA 2000 network as a compatible Garmin chartplotter to
configure and control the autopilot system.
1
Determine where to connect the CCU
À
and the helm control
(optional)
Á
to your existing NMEA 2000 backbone
.
2
In the location where you plan to connect the CCU,
disconnect one side of a NMEA 2000 T-connector
Ã
from the
network.
3
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.
4
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.
5
Route the included drop cable
Ä
to the CCU and to the
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).
6
Connect the drop cable to the CCU and the T-connector.
7
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
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
).
1
Add an additional T-connector (not included) to the NMEA
2000 network.
2
Connect the optional NMEA 2000 device to the T-connector
by following the instructions provided with the device.
