Electronics connections

[Riegfrghtl]

I just purchased a raymarine 55 vhf, an A70D chartplotter, and a Sr50 satellite receiver for my boat. In addition I also purchased a fuse block for which I will connect this electronics package to. I am sure about making the electrical connections to the new fuse block but my question is more towards the electronics. The instructions supplied by Raymarine are a little vague. The vhf has DSC feature and is hooked to the chartplotter via nmea connections. Do these wires connect directly to one another through a butt connection or is there a nmea connection block that I need to purchase? There are wires for in and out. This vhf does not support Seatalk. The chartplotter supports both nmea and seatalk. The satellite receiver supports seatalk which should plug directly into the chartplotter and power source. I am trying to get my ducks in a row to install the equipment so I would like to have everything on hand before tackling this project If anyone has experience in this area I would greatly appreciate any advise you may be able to provide. Thanks everyone! Tim

Re: Electronics connections

To start you do not need anything to run the wires from one device to the other.
Having said that I would install with a polarized plug.
At Least on my boat the radio and GPS and Depth Finder come out at the end of each trip. This to prevent theft and also because my boat sits out in the sun under a dark blue cover and the inside temperature will reach 140 degrees every day in summer which is not good for electronics.

So the GPS data out should go to the Radio GPS data in. If both are connected to the same ground you may not need to connect signal grounds together.

Also if supported by both the VHF data out can go to the GPS data in. Some GPS chartplotter will display the position of another boat if you receive a DSC position from them on.

Each unit should be connected to a fuse or if they came with there own inline fuse they can go to the 12 volt buss bar. If you have a nice fuse box I would use that but make sure you use the right size fuse for each unit. Also make sure they are labeled correctly.

I have not heard of SEATALK. Is that just a name for a network connection on your brand equipment?

Other may have heard of this.

Good luck.
