Wiring guidelines
Safely pulling the interconnection cable
• Connect a mouse line to the outer jacket of the radar interconnection cable so that the
strain of pulling is transferred to the stronger outer jacket of the cable. Use some small
cable ties to secure the mouse line to the outer jacket as well if there is sufficient clearance.
• Tape the conductors and tape the RJ45 connector to the mouse line so that it does not
get caught and bent backwards.

C Cable tie
Do:
• make drip and service loops
• use cable-ties on all cables to keep them secure
• solder/crimp and insulate all wiring connections if extending or shortening the cables
• use the appropriate length of ready-made interconnection cable
• leave room adjacent to device to ease plugging and unplugging of connectors
Do not:
• make sharp bends in the cables
• run cables in a way that allows water to flow down into the connectors
• run the data cables adjacent to radar, transmitter, or large/high current carrying cables or
high frequency signal cables
• run cables so they interfere with mechanical systems
• run cables over sharp edges or burrs
• attach a mouse line directly to the Ethernet cable or connector
Warning: Before starting the installation, be sure to turn electrical power off. If power
is left on or turned on during the installation, fire, electrical shock, or other serious injury
may occur.
Warning: The positive supply wire (red) should always be connected to (+) DC with
the supplied fuse or a circuit breaker (closest available to fuse rating). Be sure that the
voltage of the power supply is compatible with the unit.

Choose the scanner location
!
The radar’s ability to detect targets greatly depends on the position of its scanner. The ideal
location for the scanner is high above the vessel’s keel line where there are no obstacles.
When you are deciding on the location, consider the following:
A higher installation position increases the radar ranging distance, but it also increases the
minimum range around the vessel where targets cannot be detected. Higher installation
height also reduces the ability of the radar to detect targets in sea clutter.
The length of the interconnection cable supplied with your radar is sufficient for the majority
of installations. If you think you’ll need a longer cable, consult your dealer before installation.
Optional cable lengths are 5 m (16 ft) 10 m (33 ft), 20 m (65.5 ft) and 30 m (98 ft).
If you mount the scanner on a pedestal or base, ensure that rain and sea spray can drain away
rapidly, and the breather hole (A) in the base can operate.
A
The scanner should, where possible, be installed parallel to the line of the keel.
Do not install the scanner:
• directly on to a large flat roof area. Use a pedestal to elevate the scanner so the radar beam
clears the roof line. Refer to “Considerations for roof mounting” on page 10
• too high up (eg at the top of a mast), which may cause degradation of the radar picture
over short ranges
• close to lamps or exhaust outlets. The heat emissions may damage the dome. Soot and
smoke will degrade the performance of the radar
• close to the antennas of other equipment such as direction finders, VHF antennas, GPS
equipment, as it may cause or be subject to interference
• where a large obstruction (such as an exhaust stack) is at the same level as the beam, the
obstruction is likely to generate false echoes and/or shadow zones
• where it will be subjected to strong vibrations. Vibrations could degrade the performance
or service life of the radar
Warning: For dual radar installations, ensure the Halo Radar is not installed in the
beam of a pulse radar at any time.

STBY
Minimum distance to install near the
ships compass is 0.7 m (2.3 ft).
If possible, ensure that the mounting
location provides the scanner with a
clear view all round the vessel.
Do not install the Halo Radar on the same beam
plane as a conventional pulse radar. A pulse radar
must be set to STBY or OFF any time the Halo
Radar is being operated.
If installed on power boats that have a steep
planing angle, it is recommended to tilt the
scanner angle down at the front.
Considerations for roof mounting
When deciding a suitable mounting location for the Halo Radar, be aware that the vertical
radar beam extends 25° above and below horizontal for Halo20/20+ and 22° above and
below horizontal for Halo24. 50% of the power projects in a beam 12.5° above and below
horizontal for Halo 20/20+ and 11° above and below horizontal for Halo24. If the radar beam
cannot clear the roof line, this will decrease performance of the radar. Depending on the size
of the hard top of the vessel, it is recommended to elevate the antenna to allow the radar
beam to clear the roof line.
¼ Note: Where the mounting surface is constructed of any form of metal you must elevate the
radar so that the beam has complete clearance, as per Optimum performance section, else
performance will be severely impaired.
Determine scanner height
This is a guide to determine scanner height in relation to the furthest forward corner of the
hard top.

Above illustrates an installation with the Halo Radar mounted directly on to a large hard top.
This installation could suffer decreased performance as the radar energy is either reflected or
absorbed by the hard top.
¼ Note: Where the mounting surface is constructed of any form of metal you must elevate the
dome so that the beam has complete clearance, else performance will be severely impaired.
Good performance
The image above illustrates that raising the radar scanner off the hard top allows most of the

Setup and conguration
Setup and configuration of the Halo Radar has been simplified compared to traditional pulse
radars. There is no zero range adjustment (time delay), no warm up time and no burn in
required.
Make the following settings before use. Refer to the documentation supplied with your
display unit to locate the settings to be adjusted.
Adjust bearing alignment
Aligns the heading marker on the screen with the center line of the vessel. This ensures that
MARPA targets and bearings taken with the EBL are displayed accurately.
Antenna height adjustment
The antenna height is the height of the antenna above the water line. Ensure the antenna
height is set correctly, as it affects the sea clutter function. Do not set the height to zero.
Sector blanking
Used to stop the radar transmitting in the direction of structures that could cause unwanted
reflections or interference to appear on the radar image. Four sectors can be set, the bearing
of which is measured from the bow of the vessel to the center line of the sector.
Sidelobe suppression
¼ Note: This control should only be adjusted by experienced radar users. Target loss in harbor
environments may occur if this control is not adjusted correctly.
By default this control is set to Auto. Increase the suppression if there are false targets
appearing as arcs radiating from either side of an actual target (typically large structures such
as steel ships, container wharves, and large buildings).
Halo light
¼ Note: Only available for Halo20+ and Halo24 Radars.
Determines the light level of the LED accent light.
Warning: Halo Radar’s lighting may not be approved for use in your boating location.
Please check your local boating regulations before turning the blue accent lights ON.

Replacing a Broadband 3G/4G Radar
¼ Note: Some older displays may not be compatible with Halo 20, 20+ and 24 dome radars. For
information contact Navico customer service.
An adapter cable must be used if the Halo Radar is to be connected using a pre-existing
Broadband radar interconnection cable.
Before taking scanner up mast/pedestal:
1. Insert the connector of the adapter cable (A) into the scanner socket. Turn the locking collar to
secure the connector.
2. Install the first retainer across the adapter cable using the supplied screws. Tighten gently.
3. Install the second retainer using one screw only, leaving it turned to one side so the cable
channel is left open.
At mounting location:
4. Insert the connector of the existing interconnection cable (B) into the socket on the adapter
cable. Turn the locking collar to secure the connector.
5. Swivel the second retainer over cable and gently tighten both screws.

RI-10 Radar interface box and wiring
It is recommended to remove the RI-10 Radar interface box. After removing the RI-10 Radar
interface box, reterminate the connector. Use the appropriate tools to strip the 4G cable
about 20 cm to allow the waterproof cable boot to slide over the RJ45 connector. Refer to
“Waterproof cable boot” on page 17. Connect the 4G cable wires to power as described in
“Power connection” on page 18 and “Power control connection” on page 19.
If removing the RI-10 Radar interface box and associated cables/wiring is difficult they may
remain in place when a Halo 20/20+ or Halo24 is connected via the scanner adaptor cable,
with no detriment to performance.
Check the Fuse/circuit breaker rating is as specified. Refer to “Technical specifications” on page
27.
¼ Note: Halo dome radars do not require navigation data via Simnet or NMEA 2000 for MARPA
or Velocity Track to operate.

old to support radar.
Recommendations
Ensure that the correct radar source is selected and configured in the display unit. Refer to the
display unit’s documentation.
No radar
Indicates the Display and Radar have not established a network connection.
Recommendations
• Check the Radar Status LED
• Check that the Ethernet light is blinking at the radar and at the display (where applicable) or
network expansion port
• Check/select radar in Radar Sources
• Power cycle the system
• Check all connections, ensuring plugs are seated properly and no corrosion is evident on pins
• Check voltage to the yellow power control wire
• Check supply voltage/current
• Check for faults or pinch spots on the Ethernet cable and replace it
• Try another Ethernet port on the display or switch
