Default Wiring XID for SonarHub?

I'm not able to find any documentation for how the XID signal should be connected to the Lowrance pigtail adapter for use with SonarHub (and NSS Evo2). The problem is that Lowrance have previously not been using XID. Airmar OEM transducers for Lowrance have been without XID.

I had hoped Airmar had put out wiring diagram for Navico TM150M, but couldn't find anything. I've also checked the SonarHub and BSM-2 documentation.

I have confirmation that SonarHub is supporting XID.

Anybody able to help?

****Update September 22th, 2014

This thread has become quite long so the information can be a bit problematic to find.

My recommendation is to follow the table posted in post #2 and shown here as well with two modifications.


Instead of connecting Transducer O.Bare and Brown to Lowrance Pin 6, I recommended to connect these two wires to Pin 7 instead. This is for me (as an EE) more correct than whats specified in the table (which is not wrong) and is also how I have done it for the 5 CHIRP transducers I've added 7-pin connectors to myself.

***Update May 29th, 2015

Here is a table showing my preferred wiring. Airmar 1 is for single band transducers and the high (or Medium) channel of dual band transducers, Airmar 2 is for the Low channel of dual band transducers.



Make sure the two bare wires and shields don't touch, one member has reported XID malfunction if touching.

****Update March 6th, 2017

If you have a cable with too may wires and strange colors, this may help:

More information from later posts added to first post

Parts list:

Pigtail connector: Lowrance # 000-10046-001

http://www.boemarine.com/lowrance-si...-pigtail-blue/

Waterproof (IP66) 80x80x45mm (3 1/4 x 3 1/4 x 1 3/4") connection box
2 waterproof 6-12mm (1/4-1/2") cable glands
Euro type connection strip
Heat shrink tube to insulate bare wires (do not heat shrink)
Some insulated wire ferrules matching the wires


Everything except the pigtail connector were sourced from a local store.

Here is how my connection box look like

If you have the necessary skills you can of course solder. The image below is showing how it look like after soldering and heat shrink over individual wires (this is for a transducer without XID). What's left is to get the shield foils in place again. I added two small pieces of aluminum foil to the shield and used electrical tape to avoid the two shields to touch, and finally a heat shrink tube with integrated hot melt glue over the complete splice.

Here is what I received from Airmar. Looks like the XID is Yellow (pin 4).
I have also attached the diagrams for the B175L & B175H(wide) from Airmar along with an excel diagram I made.

Lowrance/Simrad Pigtail 000-10046-001
Pin 1: Depth Pos - Red
Pin 2: Speed Signal – Blue
Pin 3: Speed Voltage – Orange
Pin 4: Temp Pos/XID – Yellow
Pin 5: Depth Negative – Black
Pin 6*: Depth Ground/XID Ground - Bare/Drain
Pin 7*: Temp/Speed Ground - Bare/Drain

* Must check continuity to find the correct bare wire

B175W is recognized. In the installation menu it says B175H, but it's still correct.

The way they have done it is to use the normal analog temp input for XID and then use digital temp sensor over the XID protocol. This is the reason why TM150M is not recommended for Elite CHIRP. A B75 with pigtail can be wired to work correctly to work with Elite CHIRP and based on the measurements I've done today Elite CHIRP is using the same frequency bands as SonarHub.

Something I had hoped for but wasn't sure about was available under frequency selection. It's possible set any custom frequency within the supported frequency band. With SonarHub and B175W this is 150 to 210kHz and yes, these are minimum and maximum frequencies available under custom frequencies.

This was with HDS Touch. I'll report back when I've tested with NSS.

Works fine with NSS and HDS Gen2 as well. I have some issues with the temperature which I have to investigate further (with all three units).

What does connection of the xid wire of the transducer to pin 4 of the Sonarhub bring us?

Automatic detection of transducer type. Important with CHIRP since different transducers may have different frequency ranges and max power. A "normal" High CHIRP transducer (like B175H) has a 130-210 kHz bandwidth, B175H-W has a 150-250 kHz but max 210 kHz is currently supported by Navico. For this transducer to work as intended the bandwidth should be set to 150-210 kHz XID is also used to set correct transmit power. In addition XID gives access to internal temperature sensors in the transducer monitoring the element temperatures, if it get overheated the sounder will then automatically reduce the transmit power.

Amazing info. Thank you for your time on this.

What are the problems with the temp? Does it not work at all or wrong temp?

Wonder if pin 7 on the pigtail needs to be hooked to the rest of the bare wires?

With NSS it doesn't work with the two HDS models it comes and goes.

I've been studying the documentation. You are right that pin 7 (bare wire) should be connected. What Navico is doing is to use the ADC normally used to digitize the thermistor to digitize (and receive) the XID signal. Pin 7 is the ground used for this ADC so it should be connected. Airmar is using the brown wire for XID ground, so this is the wire which should be connected to pin 7. Pin 7 is also the wire which the outer shield on the pigtail is connected to, so for me it seems more correct to connect the O.bare together with the brown wire to pin 7.

After doing this I get stable temperature readings even for NSS.

Thanks Abbor for figuring it out

So Brown and O.bare Airmar wire to pin 7. Then I.bare to pin 6?

I.Bare to pin 6 is correct. The temp still goes to 0.0 C sometimes, but i doubt this is noise or grounding related. The rewiring made an improvement. Ive looked at the XID signal using a diff probe and scope and it looks clean. It also fails in my bench setup even if the sounder is not pinging. I suspect a software bug.

Perhaps when it is reading the XID it resets the temp to 0.

Abbor I guess you didn't wait for the factory installed blue plug? Any reason you didn't wait?

I don't believe the B175's will come with the factory blue plug.

I was told by multiple suppliers they were supposed to be out around the end of this month. We will see how long it will take though.;?

Maybe you haven't met Abbor. There is no way he would wait for something as trivial as a plug he can do himself when what could possibly be the best transducer is available for his fishing.

I have BSM-2 and Garmin 527xs in addition to SonarHub so I need the pigtail version to be able to connect to the other sounders for testing, and as stiletto wrote we don't know if B175W will come with blue plug and I will soon go on a several day fishing trip and I'm eager to test the new Wide transducer. I actually yet don't know if I will use B175W with SonarHub or BSM-2, I plan to use it with SonarHub but if BSM-2 gives significantly better performance I will use it with BSM-2.

And with a connector I would have needed both male and female pigtails for studying the SonarHub signals using an oscilloscope as I did when bench testing the setup this weekend.
