Need NEMA help

So I did try to read up n this but it gave me a headacheÖ

I have a Raymarine C70 MFD ( I know, I know) that I would like to talk to my Vesper XB-8000.

The MFD has an unused NEMA 0183 port and the Vesper has an unused NEMA 2000 port.

Is connecting them as simple as getting a converter and putting it between the two units?

No.

Totally different things. Not sure what else you have, but some 0183 devices can pass data through, allowing you to daisy chain.

Setup a NMEA 2000 small network. Use a starter kit, here is an example:

Once that is setup, use one of these to integrate your 0183:

I have the Raymarine C70 hooked up by Seatalk to a Raymarine depth finder. The vesper unit is connected by WiFi to my laptop and tablet, but I will be switching the laptop connection to USB to ease internet searches while underway.

I also have a connection to a vhf that gives the vhf location info, Iíll have to track that down. But that is a NEMA 0183 connection.

I have an old Simrad AP, Iíll look today to see if it is connected to the MFD.

What I want out of this is to have my depth info sent to the Vesper, which will then WiFi it to my tablet.

My primary nav app is AquaMap Master and the depth info will be part of my tracks. Along with date and time I can use the info to tell me to not try the same route at low tide.

The bi directional gateway (you will need one for each 0183 device and a NMEA 2000 port for each) I linked will allow them all to see each other. I too have a mix like you. I got it all talking to each other in order to use OpenCPN on a windows 10 tablet. I have a USB to NMEA 2000 adapter to hookup to the tablet.

A quick glance at the c70 marketing doc, says it already supports nmea 2000. So you should already have an an n2k port on the c70 unit. Just get a n2k starter kit, so you can connect both units via n2k. The Vesper also has 0183 output in the power cable connections.

Iím assuming your boat does not already have a n2k network. If it does, you likely just need a tee and a cable between units.

I don't believe the C70 supports AIS data on the NMEA 2000 port. But I'm almost certain it supports 0183 input from a Vesper 8000, I had an E120 set up that way for years (E and C are very similar). I think you can just use 0183 out from the Vesper into the C, you will need to set the 0183 port to 32K baud as that is what AIS requires.

OK, so I had a look at the boat. The boat does not have a NEMA 2000 network.

The Vesper power/data link is tied to the Standard Horizon VHF-DSC

The Vesper NEMA 2000 and USB port are unused.

The i40 depth finder has a 3 prong Seatalk connector on the back that goes directly to the positive and negative bus bars. The third wire is unattached.

The C70 has an open NEMA0183 port and an open DSM port.

The tablet connects to Vesper via WiFi

The PC connects to the Vesper via WiFi or USB

I want to connect the depth sounder to the Tablet via the Vesper

Use one of these:

Then use the NMEA 2000 starter kit.

As far as the cable for depth sounder you may need the other sex.
