Lowrance Marine Radars and Autopilots FAQs

What makes the Lowrance HALO24 Radar so unique?

The HALO24 marine radar revolutionizes radar by offering an almost real-time view, with industry-first 60 RPM operation at close range for the ultimate in collision avoidance. Identify hazards in an instant with VelocityTrack™ Doppler technology, and enjoy simultaneous short and long-range coverage—up to 48 nautical miles—from one compact 24-inch dome antenna.

Perfect for a wide range of coastal bay boats, HALO24 comes in a compact dome antenna and delivers high-quality short, mid and long-range detection. Monitor two distance ranges at once in Dual Range mode which enables you to keep an eye on far away weather cells while watching for collision hazards up close. HALO24 radar’s pulse compression technology means no compromises in detection at either selected range, while beam sharpening provides enhanced separation between small or distant targets.

HALO24 radar delivers a full 360 degree sweep every second, thanks to its industry-first 60 RPM rotation at ranges up to 1.5 nautical miles. These ultra-fast updates give you an almost real-time view at close range, offering the ultimate view for collision avoidance.

VelocityTrack™ technology provides instant visual feedback on whether targets are coming towards you or moving away. Simple color coding highlights potential hazards, improving your situational awareness and further reducing your risk of collision. HALO24 radar automatically checks every target in range; there’s no need to manually select individual targets, and no limit to the number of targets on screen at one time.

HALO24 radar wakes instantly from its low-power standby mode, delivering this high-speed radar coverage exactly when and where you need it. Even if your HALO24 radar is completely powered down start-up is a matter of seconds, not minutes like traditional pulse radar. Whether you’re navigating through crowded waterways or contending with poor visibility, HALO24 radar immediately cuts through the clutter to give you a clear and current picture of your surroundings.

How do I troubleshoot my Lowrance Halo marine radar?

Ethernet: all radar related data, control signals going up to the radar and radar returns to the display, are transferred via Ethernet. The exception is the old NX40/45, which uses serial connection.

NMEA 2000: heading data to the radar comes via NMEA 2000 connected to the radar interface or serial data connected to the HD radar processor. One exception is the HALO24, which gets heading data via the Ethernet connection. Heading data is required for MARPA function and radar overlay on chart. For MARPA operation, a good quality heading at minimum 10 Hz is required. The heading data, and thereby NMEA 2000 connection, is not required for normal radar operation.

Power: the radars are powered via the red and black leads to 12/24 V. The yellow lead is power control, which is to be connected to +. There is no yellow power control lead for HD radars.

General: A fault indication can occur without a genuine reason, and a simple restart (power cycle) of the system will normally restore full operation. Next step is to check/upgrade to latest software versions.

Fault indications on the screen:

‘No radar’: indicates the display unit does not see the radar. There may be no data received via the Ethernet connection. The cause of fault can be the radar, radar cable, radar interface, Ethernet connection incl. switch and the display unit itself. It is also possible the display does not recognize the radar and needs a restart.

Recommendations:

• Check/select actual radar in Radar Sources
• Restart (Power cycle) the system and check/select radar source

Most common faults are:

• Safety switch is in off position – HALO radar only

• No voltage to the yellow power control lead
• Missing or intermittent Ethernet connection, most likely the RJ45 is losing connection
• Damaged Ethernet cable.

‘No scanner’: tells the display has connection to the radar processor, inside the radar (BB and HALO) or externally (HD), but this again has lost connection to the scanner section.

Recommendations:

• Restart (Power cycle) the system
• BroadBand and HALO radars will normally need to be replaced as this is an internal fault
• Check/replace HD processor, HD scanner or radar cable.

‘No spoke data’: (constant) tells that the radar processor, inside the radar (BB and HALO) or externally (HD), is not receiving data from the receiver section.

Recommendations:

• Restart (Power cycle) the system
• Check/replace the radar cable (RJ45 connector) or Ethernet cable. A poor Ethernet connection may transfer radar commands, but radar packages are lost due to reduced bandwidth.
• BroadBand and HALO radars will normally need to be replaced as this is an internal fault
• Check/replace HD scanner unit.

‘No spoke data’ (shown intermittently). If the radar is working normally, but loses connection, the display may first indicate ‘No spoke data’ for a few seconds and then go to ‘No radar’.

If two or more displays are connected and connection to one of the displays is intermittent, the display would normally indicate ‘No spoke data’ or ‘No radar’ while the other display continues to work.

Recommendations:

• Check/replace Ethernet cable, Expander and display unit

HALO radar will not transmit: the radar system indicates ‘Radar is in Standby’, but when selecting Transmit, the radar remains in standby, indicates Radar is off or radar timed out. You may also see this alarm message:

The most common reason is insufficient power supply. When going into transmit mode, the initial start-up current for operation is quite high and then quickly reduces. The power supply requirement is 20 A @ 12 V is and 10 A @ 24 V.

Recommendations:

• Ensure power supply leads are sufficient gauge all the way through to the battery
• Check power converter to have sufficient capacity
• Check fuses and connections for any signs of corrosion or loose connections etc.
