VHF DSC wiring

I'm trying to wire my Standard Horizon GX2150 to my Lowrance 5 chartplotter.

I figured out that the AIS will not talk to the chartplotter (despite what the factory rep at the Defender sale told me).

So now I have wired the chartplotter to the VHF and despite it looking like all is wired correctly I get no GPS signal to the radio.

I even called tech support at Standard Horizon and they told me all I needed was the green wire from the GPS to the radio and the black to common.

The green is connected and the black goes to the negative bus behind my nav stations. Does this sound right?

You may need to set the communications protocol on the GPS. The manuals will tell you what the VHF wants and how to set the GPS to that.

Re: VHF DSC wiring

I have a GX2150 and the Lowrance HDS-5, and I can confirm that the AIS most definitely DOES talk to the chartplotter. I see AIS targets on the plotter display.

I also have GPS data on the VHF.

Hope you have a HDS-5 and not the Elite-5.

Having said that, I had a hell of a time figuring out the wiring. If you ignore everything anyone tells you APART from Standard Horizon, that's a good start. Lowrance's documentation was rubbish, and their technical help told me more rubbish.

Check out this page, and open "wiring Lowrance HDS series to GX2150" and wire it like that.

Welcome to StandardHorizon.com

Edit : I looked at your post again. No, do not connect the signal ground (green) to any negative bus. It should connect to the shield in the Lowrance cable, and nothing else. The goal here is to connect both sides of the serial connection to EACH OTHER and not via any ground.

Yea, it's the Elite 5 Gold I should still get DSC though (I hope).

Re: VHF DSC wiring

I just hooked up a SH GX1700 with ais and dsc to my plotter. I had to activate the curciut with the vhf's internal settings and I had to change the baud rate on my plotter. Works great.
I also got the ram with it. I can acually hear the radio at the helm now.

Re: VHF DSC wiring

I notice that all the wiring shown online is for the HDS, not the elite 5. I can't find any DSC literature related to the elite 5 wiring. WTF... I guess I got what I paid for

Re: VHF DSC wiring

So in the Elite 5 manual, on page 7, there is a menu item "advanced mode". It says this has to be on to enable NMEA 0183 output.

Did you try connecting the green wire to the Lowrance cable's shield?

Not yet. I'm headed to the boat Sunday to cruise for 10 days or so. I should have some time between beers and sailing to look at that wiring.

Thanks again, and I'll let you know how I make out.
