Updating my MFD with a few system upgrades.

[Shawn Seim]

Hello,

I am presently running a c125, CP370, HS5, and a RD 418HD. I am running the CP370 and the RD 418HD through the HS5, which then feeds the c125 via a Raynet to Raynet A62361 cable. My c125 is mounted in an aluminum center counsel with an aluminum hard top. GPS signals are received, but not what I consider to be a timely manner. I would like to add the following to my system,

1. AIS 650
2. AIS 100
3. RS 150
4. Possibly, in the future the Ray 52.

Could I ask for your help in producing a shopping list to install these items so that they may be used with my current system?

In addition to my " shopping list" I need to ask you the following questions.

A. Can I use the Seatalkng Spur cable that is supplied with the AIS650 directly into the c125?
B. Will the addition of the RS 150 necessitate setting up a Seatalkng backbone to allow interface with the c125?
C. If I should elect to live with slower GPS signal acquisition, and not use the RS 150. Can the AIS power supply come off of my house bus via the appropriate fuse, or must it be powered via Seatalkng?

I have to admit, I am just an average guy who loves to fish. I have successfully installed all of the aforementioned Raymarine equipment myself, and I am hoping to be able to do the same with my planned upgrades. I Have a pretty good grasp on working with my boat, and my installation skills have worked so far. I will gladly welcome any assistance that you can offer.

Thank you.
Shawn

Welcome to the Raymarine Forum Shawn,

For the benefit of others who may be viewing this post and considering whether an external GPS sensor or external GPS antenna would be necessary, please click here to view a FAQ addressing this subject.

Q1. Can I use the Seatalkng Spur cable that is supplied with the AIS650 directly into the c125?
A1. Like any devices which is designed to communicate via SeaTalkng / NMEA 2000 communications protocol, each such device must be individually interfaced as a spur to a powered and properly terminated SeaTalkng backbone. In this case, the AIS650, c125, and Raystar 150 GPS Sensor will each individually be interfaced as spurs to a spur to a SeaTalkng / NMEA 2000 backbone. Information concerning how to construct a SeaTalkng / NMEA 2000 backbone and listing all of the available cable lengths (and corresponding part numbers) may be found within the SeaTalkng Reference Manual.

Q2. Will the addition of the RS 150 necessitate setting up a Seatalkng backbone to allow interface with the c125?
A2. Yes. See the response to Q1.

Q3. If I should elect to live with slower GPS signal acquisition, and not use the RS 150. Can the AIS power supply come off of my house bus via the appropriate fuse, or must it be powered via Seatalkng?
A3. Please refer to the FAQ addressing when an external GPS sensor or external GPS antenna may be necessary within a system. Of key note is the fact that insufficient GPS signal strength may reduce the accuracy of the GPS position FIX or cause the GPS FIX to be intermittent. It is strongly recommended that a Raystar 150 GPS Sensor be added to this system given the reported acquisition issues. Regarding the AIS650, please note that it is not designed to be powered from a SeaTalkng backbone and must be powered using the Power/NMEA 0183/Silent Mode Cable within the AIS650's package. Choice of which of the vessel's power circuits will be used to supply power the GPS sensor is a subjective one.

Thank you Chuck! Looks like I've got a bit of research, and shopping ahead of me.
