Default Lowrance Radar overlay

Jim,
Just got an LRA from a friend, he had it set up with a 113 with heading sensor and a NEMA 2000 gateway for overlay. He got the gateway straight from Lowrance. He cant remember the model numbers, what can you give me as for as a heading sensor and gateway so I can get the overlay.(Assuming I can get overlay on my 7600HD)
Thanks Dan

You can use a NMEA2000 Gateway of NMEA0183. The NMEA 0183 way is a little cheaper using the KVH Autocomp 1000 http://www.byownerelectronics.com/st...9&cat=0&page=1

For NMEA2000 you can use the Maretron Gyro compass: http://www.byownerelectronics.com/st...4&cat=0&page=1

I want to order the heading sensor and the gateway, I have a blue NEMA2000 network and would need whatever it takes to get this hooked up.

Default RE: Lowrance Radar overlay

Jim,
After looking at your site it looks like the Maretron NEMA2000 heading sensor is only about 100 more once you buy the 0183 sensor, gateway and adapter cable. Am I missing something and is there anything else I would need for the Maretron?
Thanks Ill give you a call hopefully tpmmorrow.
Dan

Dan,
I got the Maretron Heading Sensor from Jim a couple of weeks ago... Heading sensor was connected into the NMEA 2000 network...My LCX-111 instantly recognized it and allowed radar overlay function to work... The sensor comes with at least 25' of cable and a connector for the heading sensor... I took a spare Lowrance NMEA 2000 cable, cut it and spliced it onto the cable supplied with the sensor, added a Lowrance "T" and it was that simple!

It is that simple, nmea2000 is great!

You still have to splicw wires. I would think for 500 it would come complete. Does it have red or blue?

I have an older Lowrance with the proprietary blue connector so I was forced to spliced...I believe the red connectors used on the newer Lowrance stuff is not proprietary and connectors are available... The Maretron connector which connects to the sensor was easy to install...Strip 4 wires per the enclosed directions and attached to the NMEA 2000 connector via screws...No soldering needed and the connector was very well built.

It has red. Red = micro-C = NMEA2000 Standard.

Is there an update for my 5" Lowrance units so I can have radar overlay?

An update came out a couple of weeks ago, I can't confirm it allows radar overlya but it certainly has a lot of enhancements. If I get time I will install it on one of our demo units to see what it does.

What changes are made in this update?

* Added Lowrance HD radar support via serial communications
* Added Greek language
* Added Polish language
* Added ability to take a screenshot capture of the display on the unit and save to a card/hard drive – In Screen Snapshot mode, use the power key to capture the screenshot
* Added Navionics Platinum support including 3D view and panoramic photos
* Added support for the Lowrance Broadband Sounder-1
* Updated language translations
* Improved sonar digital depth tracking in weeds and over bluffs
* Improved Navionics support
* Changed Map/Sonar/Radar page to be resizeable
* Includes all features from previous updates, including:
o Modified backlighting properties
o Improved ethernet stability
o Moved the Cancel Navigation menu item to the top of the system menu
o Many modifications to radar settings and features
o Modified SD/MMC data storage properties
o Added support for HDM NMEA0183 sentence
o Improved Navionics card support
o Added sonar sharing over ethernet
o Modified Auto-Sensitivity feature
o Modified memory card reading functionality
o Enhanced Navionics support
o Enhanced NauticPath electronic chart support
o Enhanced sonar noise detection

Default RE: Lowrance Radar overlay

Dan, I also want to add a heading sensor to my Lowrance LCX-111. My questions are: (1) is anything other than the maretron sensor required and (2) what Lowrance software should I have loaded so that the radar will pick up the overlay function? I have an LRA-1000 radome.

Thanks, RJZ

Jim, I just got a Maretron compass and installed it in my NMEA 2000 network with my LCX 111. The software is 2.1.0 My system did not recognize the compass. What software do you have loaded on your unit?

Thanks,

Ricky

I don't have a Lowrance unit. Is your nmea2000 network set up properly. Did it work prior to the compass? Did you do the search for bus devices on the 111? You can call me to help you troubleshoot.

Default RE: Lowrance Radar overlay

I have a Lowrance LCX-113cHD getting input from an LRA-2000 radar, and I just purchased a KVH Autocomp 1000 heading sensor so that I can overlay the radar on my chartplotter. Since the Autocomp is NMEA0183, can I just connect it directly to the NMEA0183 input on my 113; or do I have to convert the signal to NMEA2000 and then connect that to the NMEA2000 input on the 113? I guess I'm a little confused from the above posts as to why I would have to convert to 2000 if the Lowrance already has a configurable 0183 input. Am I missing something here? Any advice would be greatly appreciated. Kindest regards.

Just connect it to NMEA0183 on the Lowrance unit and you'll be good to go.

Thank you, Jim. Hopefully I'll get it hooked up this weekend before the snow starts to fly here in upstate NY!

Any recommendations on what would be the best “Level” to set the Damping function to on the AutoComp 1000 Heading Sensor? I have a 30 foot Baha Cruiser Weekender with a cruising speed of about 18 mph. Most of my time is spent trolling on Lake Ontario where the wave height during my fishing trips are typically 3 ft or less. Before I solder up the wiring harness I would like to know how to bias the damping input wire for the best level (1 - 4). By the way, this compass will not be used (yet) as an input to my autopilot, just to provide the overlay for the radar. Thanks in advance for your help.

Honestly I never mess with that wire. I think it might say something in the lack of instructions about it and how you don't need to touch it.

Default Re: Lowrance Radar overlay

There's 2 wires that have to be biased to set the damping level, which is how long the compass averages its readings for before it provides new data. With those 2 wire unconnected you get the longest averaging period of 14 seconds (great if you're in the Perfect Storm); or with them both grounded you get the shortest period of 4.5 seconds (best on calmer waters). The other binary combinations are provide intermediate levels of damping. I was thinking about biasing for Level 2 which is ~6.0 second averaging. Does that sound reasonable for Lake Ontario waveheight and weather conditions?
