Dual E120 Classic to e125 helm upgrade

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Heiri,

General comment: If appears that some of the items which you have identifed within the vessel equipment list may not have been correctly specified for a vessel equpped in 2007 with new Raymarine products and/or E-Series Classic MFDs. Specifically, ST80 products were not sold/manufactured during the period specified ... it may be possible that you have a ST800x (where x=0, 1, or 2) ... most importantly, we would need to know the model of autopilot course computer which was installed onboard the vessel. Also, while Raymarine produced a SR50, it was not compatible with E-Series Classic MFDs ... it is possible that the vessel was outfitted with a SR100, SR6 or SR150.

Q1. I can not find a Raymarine wiring diagram for my boat in any Sea Ray downloads, as they all contain the prior SeaRay Navigator documentation, despite the fact that it is a complete Raymarine system. It would greatly help me in tracing wires to breakers and components if you could find it for me on your end, since you did all these boats routinely?
A1. Unfortunately, the requested diagram is not available

Q2. assuming that I am not the first guy to upgrade a dual E120 system to e125s, is there an easy how to guide of what existing components and wiring I can leave in place and what has to be redone (e.g. new radar cable) or added?
A2. While no guide has been written on the subject. a FAQ has been generated within this Forum to address this subject. Please click here to view a FAQ addressing this subject.

Q3. while not fishing, I would like to install the Downvision capability, but could not identify the matching components. I assume I need a CP100 (?) unit and a tilted transducer for my 19 degree deadrise hull, but I don't find compatible order parts in the selection charts. Can you help?
A3. If installing a an MFD an a/c/e/eS/gS-Series MFD lacking internal CHIRP (conical) / DownVision circuitry, then it will be necessary to install a CP100 w/compatible CHIRP / DownVision transducer. In this case, an A80350 CPT-120 thru-hull transducer would be recommended.

Q4. what additional components like couplers, switches, specialty cable will I need?
A4. Please refer to the FAQ referenced above. Unfortunately, we cannot advise on cable routing lengths for specific vessels.

Q5. During transition (i.e. until next haul out, when i can do a new thru-hull transducer) can i still use my old depth sounder? Can I leave the old depth sounder as a redundant data source on the network?
A5. It is quite likely that you may be able to do so. However, in order to confirm it would be necessary to have you identify the make/model of sounding device which is presently installed onboard the vessel.

Q6. Will my first generation Sirius Weather SR50 still work?
A6. See my opening comments. Should a SR100, SR6, or SR150 actually be installed onboard, then it may be retained for use with

Q7. The boat is equipped with Cummins' SmartCraft to monitor propulsion, fuel etc. Will this interface with the e125 system and how?
A7. It is recommended that the vessel's engine manufacturer be contacted to determine whether your specific engine system may be fitted with a SmartCraft to NMEA 2000 Engine Gateway. If so, then click here to view a FAQ addressing this subject.

Q8. We have satellite TV (currently a 2008 SeaTel). Can I split the coax cable based signal and route the TV signal to the e125's? Conversely, I assume I can route the e125 read-out to my TV's (through DVR, or input switch?) I got confused with the connection explanations in the eSeries manual.
A8. The screen image of the 9" and larger e/eS-Series MFDs may indeed be repeated to a TV/Monitor supporting 720P resolution. Raymarine offers an accessory cable to support this feature. Similarly, these MFDs feature support for up to two NTSC/PAL video inputs. Interfacing the satellite TV receiver's NTSC/PAL video output to one or both (may required a video amplifier/splitter depending upon the strength of the video signal being split and the lengths of video cable being run) of the MFDs will support displaying video from the receiver onto the MFDs' screen.
