Well toys are in (HDS8 - LSS-1 - GX2100) but boat is not ready yet so I'm left to look at the new electronics and try and figure out how to connect it all. I was looking at the Standard Horizon wiring diagram to the HDS 8 and was a bit confused. u5Mm0PYbwhLjS7WzdaqZo9H5iCbmYDa2my98ztG0n8A?feat=directlink

It calls for a jumper between the shields of the COM 1 and COM 2 wires from the HDS NMEA 0183 connection.

I only see 1 shield on the HDS NMEA 5 wires (shield, Green, Orange, Blue, Yellow) cu3XKiJZ7yyK8zUN5C9qqtH5iCbmYDa2my98ztG0n8A?feat=directlink cu3XKiJZ7yyK8zUN5C9qqtH5iCbmYDa2my98ztG0n8A?feat=directlink

Am I missing something? What shields are supposed to connected?

RobP ... you have missed anything.

All you need is the single NMEA ground connection from your HDS 8. It does not need to be jumpered.

The yellow wire from the HDS provides GPS position data to the GX2100; the orange wire receives DSC radio from the GX2100; and the Green wire receives AIS info from the GX2100.

The shield wire from the HDS and the green wire from the GX2100 are connected to a common ground source.

Thanks Tom.

I have pictures of your install up as inpsiration. I'm hoping that I can make my install half as neat.

Standard-Horizon have done a wonderful job in providing precise information for interconnection of their GX-2100 VHF Marine Band radio with AIS receiver to various brands and models of chart plotters.

In electrical wiring the term "jumper" generally refers to a short conductor that connects two closely spaced terminals together.

In the Standard-Horizon instructions they appear to make reference to the two serial data interfaces on the HDS-8 or HDS-10 as having separate shield conductors, when in fact they have a single, common shield. As Tom notes, you connect the single shield to the GREEN wire.

When you have the AIS receiver data output connected to your HDS-8, I would like to see a screen capture of the display when an AIS target vessel is shown. Thanks.

Rob--Also, be certain you configure the HDS-8 to have dual serial data interfaces. There is a configuration option in the set-up which creates the second serial data interface. To accomplish this, follow this procedure:

--hit the MENU key twice;
--scroll to SETTINGS and press ENTER
--scroll to NETWORK and press ENTER
--scroll to SERIAL PORTS... and press ENTER
--scroll to PROTOCOL and press ENTER
--scroll to RS-232 and press ENTER

Select the baud rate for the serial ports to be

COM 1 = 4800
COM 2 = 38400

I'd like to see a screen shot too as I still have not bought the multiplexer for my twin hds-5,s and gx2100 to get the AIS to display

Tom, I was wondering about the pin terminal blocks you used for the NMEA 0183 wires. Did you use a pin connector at the end of the wires or just put them into the block? Do you apply di-electric grease to prevent corrosion?

Jim/Steve once up and running I'll try to get some images.

I carefully solder the exposed wire and insert them into the block. I put a thin coat of dielectric grease on the soldered ends. I've never had any issues with corrision using this method.

Sorry Rob ...... forgot to post the block. You can buy these at Radio Shack for $3.00 Two%20of%20a%20Kind%20Electronic%20and%20Fishing%20Upgrades/7. jpg?t=1291904193

Tom, Thanks.

$3 ? - Guess it goes to show you that anything sold for boats is 4x what it is elsewhere.,7688.html

Finally got the electronics all installed and took the boat out on a couple of runs this weekend.

I wanted to put some of the screen shot up showing the AIS information from the GX2100 to the HDS 8.

Not a lot of AIS equiped boat out this weekend but enough to to check it out.

Here is the To-Kalon as seen on the HDS chart plotter:

AIS Vessel Detail:

Data on GX2100:

Picture of To-Kalon:

Information on T-Kalon:

A quick summary:
1 - AIS is a neat toy in this area but there are so few boats that use it and SO MANY that don't I don't see it being a huge asset for me, but we will see.

2- The GX2100 is not as intuitive has I had hope. I'm gonna have to break out the manual.

3 - The large channel knob easily get confused with the volume. Can't tell you how often my wife changed channels on me.

4 - I need to play with the volumes or clean my ears out but I had a tough time hearing some of the transmission unless the volume was turned up, see 3 above.

I still need to play with the radio a bit to figure out some of the features and what I will actually use.

Thanks for the screen shots and photographs. They are great.

It seems that AIS will be a must-have upgrade for me next boating season. I plan to get an AIS receiver installed as soon as I get the boat out of storage in the spring.

Thanks for the feed back, you soon get use to selecting the right knob and the menus on the GX2100

I cant justify the $200 for a multipler to get AIS on my twin HDS-5,s I think I would rather put it towards a new overhead HDS -8
