Question about Lowrance GlobalMap 4800 GPS Chartplotter Receiver

2 Answers

I have a GlobalMap 2000 with a SAM-1 (not SAM-SD). When I purchased the boat, both a speed/temp sensor and a sonar transducer were install on the transom, but the cables were both cut. I have been able to purchase both the sensor and tranducer, but I cannot determine how to plug in the speed/temp sensor. After 45 minutes of being on hold with Lowrance, the support person said that I needed the SAM-ST to use both. Is this true?? and if so, why would the previous owner have both mounted?? -Joe C

    1. The main display unit is working
    2. The maplink is working
    3. The SAM-1 unit works now that the cable has a transducer hook to it
    4. Where/how do I plug in the speed/temp sensor?? or can I use a speed/temp sensor?

    I have read the pages noted, but as you can see the pages refer only to SAM-ST and not SAM-1. Do you have available reference material for SAM-1?

Hi

Not enough info to diagnose your problem. It sounds like a networking problem. I couldn't find a manual for the sam-st module so I'm not sure how you have it hooked up. Typically with these devices only one would be hooked up to the SONAR module, and it would then share the data with the other display via an ethernet or NMEA2000 network. The erratic behavior of your bluewater could be due to some sort conflict with the current coming from the GlobalMap2000. Do you get the same problem when the 2000 is turned off? Have you tried running the GlobalMap2000 with the bluewater turned off?

All transducer connections are sealed and a cable failure would mean replacing the entire transducer and cable. The only thing I can think of that would cause a simultaneous failure would be possibly a screw from some other installation that happened to pierce both cables at the same time.

Is the SAM-ST getting power? It should have an LED indicator that lights up when turned on. If it is on make a note of what color it is and how it is flashing. Usually green indicates a working model, and some other color represents some kind of internal failure.

Thanks for contacting Fixya

Garmin 551s sonar stopped working, no bottom definition or ability to see fish GPS charts and speed all work It shows 3 step image repeats top of the screen / water surface has the transducer packed


Check you transducer cable route and connections. Look for kinks, punctures, & tears in cable. Visually check the transducer for damage. #2 check the units operation on a friends boat with the same set or research a local marine repair shop to check ops. Best of luck on the problem.

My lowrance elite 4 HDI goes black when i get on plane so my backtrack feature doesnt work


The speed of your boats travel only directly affects your sonars ability to read the water depth.
your backtrack feature is GPS based. These is not affected by your boat being on plane.

Your screen being black sounds like your sonar is losing bottom contact due to air bubbles passing under the transducer. This is a common occurrence with most boats.

Add some details regarding what your seeing and we can help you get a better handle on your difficulty.

Does the x510c have a speed and temp transducer or just the paddle seperately


Hi Rick

There is only one transducer. for speed/temperature. From page 2 of the owner's manual (see link below)
"A single-frequency with built-in temperature
sensor is packed with the X-510c"

Hope this helps and happy boating!
-Steve

Y cant i mount my structure scan transducer on the bottom of the boat


This is what the manual says:
The StructureScan transducer can be mounted on the transom,
jackplate, step or directly to your boat's hull.
When mounting it directly to the hull, you must purchase a high-
quality, marine grade above- or below-waterline sealant/adhesive
compound.

well if the side scanner is a stern mount. Then opposite side would be best and scanning away from other transducer. Too much wattage and they will mix signals and give you two blank screens. You can mount together but run one at a time. Aloha

Sonar only reading the surface


First, ensure that the transducer face is pointing down when the boat is level in flat water. You may want to do this step like a tv antenna, adjusting the angle of the transducer while watching the screen.
If that doesn't work, then try moving the transducer further into the water and repeat step one.
Sonar systems are (largely) directional, and will work best when parallel with the seabed (or lake bed etc)

Lowrance Globalmap 2000


The screen is the weak point of the 2000's.  I have one myself, and without warning a number of "lines" appeared on the screen, getting progressively worse over time.  
Perusing other forums, it seems we're not alone.  Unfortunately the only "solution" I've found thus far is to purchase a new head unit (eBay is a terrific source!).
