So I installed it and the radio works great, however the internal GPS/clock when connected to the 'black box' wont work. I connected different Garmin HH to it to check conections and the Garmin talks to it but the RM Sea Ray Navigator II must be 'speaking' another data language. Any ideas how to get it to work? I have no idea what the GPS product is but sense that it is intergrated into the SR Navigator unit! Thanks
 
the 'mushroom' cap that came with the boat 2005 390 DA Works perfect wtih all the other GPS stuff
 
The antenna, if a RayStar 125 has two output settings inside the dome. One is Sea Talk which is for Ray Marine gear and NMEA which is universal. You may need to make sur eyour data feed to the radio is on the correct setting for your radio.
 
ASUREYEZ..just re read your psoting. OK, if I change one of the settigns in the dome wont that throw off the RM GPS?
 
You need to provide more info.....

Where are you getting the feed from to supply the ICOM 702 with GPS information? From the SR Navigator or another onboard Raymarine piece of equipment like an E/C 80/120?

The ICOM most likely wants to see NMEA...not seatalk as Chad spoke of above.

Assuming you have a Ray125 antenna, the choice between the unit putting out seatalk or NMEA is determined by the way it is physically wired as seen below...there is no 'setting switch' so to speak...

I am having the same issues with my RayMarine equipment and my Standard Horizon GS1500. The RM talks using the Seatalk proprietary system and the SH uses NMEA. I understand that I will have to change the RayMarine electronics to use NMEA instead by changing the displays data feed software selection. You may have the same issues. NMEA is universal and you should be able to select NMEA over any proprietary "talking" system in your electronics. Check your owners manual or their website for FAQ.

BTW, I bought a new RayMarine GPS antennae (RS125) to replace my older RS120 through BOE-Marine and they had by far the best price and free shipping...

Thank you BOE...

The differences between the 120 and 125 from a user perspective are that the 120 was hardwired either NMEA, or Seatalk, so two separate units. The 125 can be configured either one or the other.

I'm not sure the following will explain your problem, but it might help you diagnose it better.

Depending on the display unit it does not matter whether the RM antenna feeds the display via SeaTalk, or NMEA. I have my depth and GPS data coming into my RL 70 CRC via SeaTalk, and data is being output via NMEA to my Smartcraft display. A couple of things to think about. Again depending on display, to get data from RM to your VHF, you may need to turn on the NMEA output, and then you may have to also configure what data 'sentences' are transmitted. Another thing I found when getting my RL70 to talk to Smartcraft was that SmartCraft needed an input cable with an inline resistor with my particular display. The RL 70 was basically talking to fast.

Yea, I get it. I will try the NEMA output from the SR Nav to the ICOM 802 (sorry not 702)
 
There... I deleted my responses. You obviously don't know what the hell you are doing and it's kinda pointless to put up explanations only to have insults coming back.

Good Luck... That seems to be all you have to work with.
 
WHAT? As uusal for this hyper senesitive site, you mis-read my 'diminishing returns" comment. WHAT I MEANT to imply was that it's getting to be too much trouble for ME and that just to have the GPS read-out on another radio, although cool was TOO MUCH TROUBLE FOR ME to deal with anymore. If the fix was simple, them I would have done it. As it is, I'll just use my VHF radio for any distress calls i might (hopefully not) have. There, feel better? didn't mean to insult you!!!!!
 
One other possibility you could check is that IF you are already trying to feed NMEA signals to the radio, you may have the NMEA +- or In and OUT wires reversed, that gives you nothing. In such a case you trace the wires to their labels and make sure you're using the correct polarity for NMEA.

Now that probably kicked your ball right out of the park!

RM equipment is pretty good about allowing Sea Talk data in to a piece of gear and when activated wil let you pull out a NMEA link to a down stream to a different piece of gear. If for instance your antena is sending to the plotter its feed in Sea Talk, you can pull out of the RL70, a NMEA feed to your GPS, then from the GPS to the radio (daisy chain). You might find in the wiring compartment you also have an NMEA spliter, nose around, take good digital pics and make a drawing of what you see. Post them here, were much better when we don't have to work with air pictures.

Don't mind Gary, he's on drugs from a serious injury and he's cranky!

Thanks, and he is on drugs. The Garmin output to the Icom worked perfectly, regardless of the polarity, therfore, the ICOM isnt the issue. I need to see for myself if the SR output being NEMA will do the trick. I'll try tomorrow, thanks for the advise!
 
FOUND THE PROBLEM!! (I think) There are two BNC connector outputs on the AUTOPILOT box. One marked SEATALK and the other NMEMA, GOING WITH THAT . It works
 
spoke to soon...no workie!!!agagagagagagagahhhhhh
