Heading Sensor

[lamoon78]

I have a Ethernet box but its full it would be cheaper to buy just another heading gps sensor Than Ethernet box and cables. Question is would two heading sensors right next to each other cause any issues.

[Wayne P.]

Explain your entire electronics setup.

I don't understand why adding a Heading Sensor would have anything to do with a 5 Port Switch decision.

A heading sensor operates on a NMEA2K backbone which is a completely separate setup than anything networked. Examples of true heading sensors would be the Lowrance Point-1 or the Garmin 24XD. The Garmin Steady Cast device is a heading device, but it lacks GPS connectivity.

Humminbird's heading sensor is a combo with GPS and connects directly to and is powered by a display. AS GPS HS

I have a network and its full. I recently added a Helix 12 to bow with 360 and mega live. My thinking instead of adding another Ethernet box to basically just to share things could I not just add another heading sensor to connect to the 12 not interested in sharing waypoints from the 12 its a stand alone unit just for 360 and mega live is all its used for.

If you don't network everything, you are just asking for trouble from a Sonar crosstalk standpoint.

I have 3 G2N 10’s Helix they have been networked. I added a Helix 12 G4N a 360 and mega live. Currently the 12 360 and mega live are stand alone. Can you Ethernet all these together without issues due to 3 units being G2’s

So true as I am dealing with this now as the only way I can get my Mega Live and Target Lock to work like it should all day is to separate it from network. When everything was connected I would constantly get trolling motor connect / disconnect and would make target lock drop out and stop working. When I have stand alone unit with just trolling motor and ML/TL connect nothing ever drops or says disconnect / connect.

Now that it is stand alone I have to shut Apex 16 off at console and stop sonar on other apex 13 at bow to get ML image to clear up.

I had the trolling motor disconnect/connect issue with my Ulterra Quest motor and it was driving me crazy. As it turns out, one of my cables wasn't tight on the 5-Port Switch. A failing port on a 5-port switch can also cause this issue.

I guess no answer for my question and I explained my setup in my last post but someone jumped in and threw it off.

You had pertinent answers from several people. The main part is no you cannot have sonar that is not part of the network as the sonar will not be synched with each other to prevent crosstalk. I will add the sentiment seems to say “if you need to use the stuff you have and add to it just buy another switch”. It costs a small amount more than the Heading sensor,but should solve your situation. Probably 2 more ethernet cables as well. JMO Bob
Item B. If you still want another heading sensor; the following link(page 9 in particular) will tell you about magnetic interference. The distance between the 2 compasses might be critical. Link: https://johnsonoutdoors.widen.net/co...ory-Manual.pdf

Sonar had nothing to do with my question but thanks read it next time before responding.

I totally disagree with you here. When you explained more about what is going on, you indicated that you might not netowrk everything. The only way Humminbird can manage sonar crosstalk is to be able to "see" all of the sonar sources across the network. If your Mega Live isn't on the network with everything else, then you are just asking for crosstalk issues... which I had previously commented.

No worries. You will never get another response from me.

[MCIPinkie]

It seems to me the proper question of the OP is:

"What are you trying to accomplish with this collection of hardware?"

Trying to make Randy's "Haul of Shame"?

Seriously, I don't see how any of us can help you without some idea of what you are wanting to do.

If it was me, I'd go fishing.

I don't think he knows what crosstalk is.

Its not on the network and works flawlessly unlike others that have issues. My initial question was adding another GPS Heading Sensor to my 12. The three G2N have been network for years I recently added the 12 as a stand alone only used for mega live and 360 it has nothing else ran to it except the bow heading sensor for 360 to work right. I tookthe bow sensor away from the 10 on the bow thinking that it would read from the sensor off the stern being all 3 10’s are networked but it doesn’t. I was asking if I added another to connect to the 10 on the bow would they interfere with each other being that close. So basically the 10 is only used for mapping now nothing else. The 12 does mega live and 360 there is no 2d I took it out. If that explains it any better.

A heading sensor is a magnetic compass, if you put it next to another magnetic compass, they can screw up each other since magnets affect magnets. If you have them separated by about 6+" they may not affect each other. IF you purchase an additional AS GPS HS, put them that close together and find out before you mount the second one permanently. All that other stuff that has been posted about what each unit does is irrelevant concerning what you asked about the heading sensors in the second sentence of your original post. All you have to do is connect the antenna to the unit you want and look at the Chart Views on that unit and another one to watch the position icons and/or turn on the Heading Lines to see if they affect each other within the distance they are separated.
