Adding Raymarine C70

[fishmiami]

Hello,
I have a Raymarine C120 on my boat now with GPS, Radar and Depthfinder (DSM300). I'm putting a tower on the boat and I want to add a C70 to the tower. I was wondering if anyone knew what cables I would need to connect the new C70 to the current system. I'm hoping it's not too difficult.

Thanks

I don't think the C series will network.

You can share the GPS between C-series units, but if want to use the DSM, you have to get another one for the C70. The C-series can not be networked to share the DSM or Radar. I verified this with the folks at Raymarine.

Thanks for the replies. That sucks, I'm guessing I also need a second transducer, to get depth to the C70 in the tower. I didn't realize the C series didn't network, I thought you could have 3 screens all sharing the DSM etc. Don't know what to do know.

you might want to talk with raymarine. see what would happen if you put an E series master at the helm, what info could be networked TO the c120 via their seatalk, nmea0183 or nmea2000. if you can get what you need, you'll just have to have a larger display in the tower than you anticipated (or buy a whole new E network setup).

you'll need to talk with a good tech person since this may not be in the "manual". i only suggest this since i have directed several application installations to computer systems that they said "could not be done". good luck.

An all e-series network is the only thing that will help. The sharing of the DSM, radar, and weather all require Seatalk HS (aka Ethernet). The c-series do not have the HS port, so networking it with an e-series is not possible.

understood, but it does have all these comm protocols. something might get him what he needs on a ray to ray basis. just saying.

I originally figured I could just run a Seatalk cable from the C120 to the new C70, and that would be it. I really don't want to put another transducer in the boat, the one I have now is custom installed and flush mounted.

I'm thinking I could run a cable from the tower down to the DSM and when I'm going to use the tower, unplug the C120 and plug in the C70. Do you guys think that would work??

[gotumon]

The 2 c's will share position info, depth info, etc and any data that will be found in the sentences through seatalk. That will allow you to see the go to waypoint on both and know the depth, speed sog, cog, ttg, bearing, distance to waypoint , heading, etc, but there is no way to share the video. The new wide c will network 2 units.

[fishmiami]

So if I run a Seatalk cable between the two, I will get a digital depth readout on the C70. If thats the case it will have to work for now. Thanks for the info

[gotumon]

You will have to be sure to select a screen or the data bar that will show depth as a choice. Not a problem using the databar setup in the menu.

I'm looking to do something similar, ie, adding a C70 or C80 to an existing C120 install. To make this work, is there any difference between using Seatalk vs Seatalk2 to bridge units?

[gotumon]

As I recollect, the C won't use seatalk 2. The seatalk network works in both directions as opposed to NMEA 183. You just connect the units together and there you go!

[Rambunctious]

I'm not sure I understand, Steve. The back of the C120 has a Seatalk2 plug (I assume the C80 does as well), and the installation manual mentions its existence. Actually, it's the only connection not currently being used in my setup so I was hoping to just run a short jumper between the two units and have things work. But none of the example installed configurations in the manual utilize seatalk2, and it sounds like you're thinking seatalk2 doesn't work on the C series. I guess this isn't quite as simple as I thought.

[gotumon]

The seatalk 2 setup is for the input from the Sirius Satellite radio and weather as well as st290 instruments. The standard seatalk port- the one with 3 prongs and a half moon plug does the data transfer. A simple seatalk cable from the back of one unit to the other will do the job. If the ports are being used, get a seatalk Junction box- Part #D244, and a seatalk cable. Take the seatalk cable from the back of the present unit and plug it into the 244. Then run a cable from the new unit into the d244, and use the new seatalk cable (1m will do it) and plug that into the existing unit and the junction box. Seatalk runs in both directions as opposed to NMEA . You will be in business. Please drop me an email or give a call if I can help in any other way. gotumon@comcast.net
