    Connecting NMEA 0183

    Thanks @LeCanard am I reading you correct that TX_A (-) and TX_B (+) should be connected to Input signal and return and if not working - try the other way around? I've tried both - TX_B (+) to Signal and TX_A (-) to Return looks like some kind of connection established, but I still get a syntax/parity error. Could it be related to H5000 sending a checksum and H2000 not understanding what a checksum is?

    Connecting NMEA 0183

    Thanks, the H5000 is the sending side, not the the receiving one. I dont think there is a setting for checksum for NMEA 0183 in nor H2000 nor H5000 though. Garmin looks really nice, but I'd prefer to get B&G displays to be able to display targets/polar data etc. out of my H5000 Performance CPU and not rely only on Expedition to feed Garmin with data. Using my old 2020 displays would be a "temporary" fix to invest step by step ....

    Connecting NMEA 0183

    I’m trying to link my B&G H5000 CPU to my H2000 20/20 displays via NMEA 0183 (either via the performance processor or the NMEA FFD). My H5000 CPUS has …. #1: TX_A (-) #2: TX_B (+) H2000 Performance processor has … (#21: “Ground”) #26: ”Input return” #27: ”Input signal” Alternatively NMEA FFD has …. Brown: “NMEA Input Signal” Blue: “NEMA Input Return” (Black: “Ground”) I’m guessing the H5000 is NMEA 0183 v2.x or 3.x but H2000 is only NMEA 0183 v1.x (with the signal/ground connection rather than the newer +/- connection) From what I understand I should connect "NMEA +/A" to "In" and "Shield" to "G", but nothing in the above manuals really corresponds to that. What is the correct way to wire these together? All I get from H2000 is Err.3 “Syntax or parity error on received NMEA data.” I’m simply sending VTG (Track made good and speed over ground) at 1hz 4800 Baud from H5000 trying to show SOG or COG on the display – but all I get is Error. I’ve tried both input 1 and 2 on the performance processor, calibrating NMEA MDE accordingly and using the NMEA FFD for the connection.

    Best way to get code zero luff tension?

    @MultiThom and @solosailor my spinnaker halyard is a fractional halyard (Seaqust Prima 38) the mast is pretty stiff (carbon) and I do have pretty powerfull 48:1 backstay - but still with the fractional code zero - do think the backstay along with a grinded single halyard alone (no cascade at the tackline) will give me enough tension to sai the higher angles? I'm hoping to hoist at perhaps TWA 70 in light air <6 or 8 knots of wind.
  5. I’m getting a 65% code for next season, what is my best option to get enough luff tension? I have 2 spinnaker halyards, I’d prefer not to go to 2:1 as I use both for spinnakers, but perhaps that is my best option? If I do go 2:1 can I realistically hoist a spinnaker from it - or will that leave me with one halyard for each sail? If I go with 2:1, can I skip a tack line and just snap the furler directly to the bowsprit/ bobstay? As I have symmetrical kites I will never use the code to go downwind more than say TWA 110 I’m getting a custom 60cm bowsprit so there is an option for 2:1 or more in the tack line/ bobstay - if this is the better way, what’s a smart design? I’m seeing many different solutions. The boat is a Prima 38 (with symmetrical spinnakers) the code will be 75m2 and hoisted at 15.5m the sailcloth will be Maxikote polyester as laminates will be costly in our rating system. Current halyard is Dyneema 10mm SK75 do I need something with even less stretch? Appreciate any hints as I’ve never had any code sails onboard.

    Pilot calibration secrets (B&G H5000)

    I'll try and have a go at my hard over time, I haven’t changed it since first commissioning I have an ultrasonic speed sensor, so to me a fould paddle wheel is not the problem. @BobJ cruising speed - are sure you adjust the correct one? There is both cruising speed under "Steering > Limits > Cruising Speed" which you should be able to set at 7 and there is speed source "Steering > Speed Source > Manual" where 0 means you let the pilot select the best available source of speed input (1st BSP > 2nd SOG > 3rd Cruising speed). If you set that one to 7 you override BSP and SOG if they are available.

    Pilot calibration secrets (B&G H5000)

    @BobJ I was recently told a typical TWA correction table to start out with was ... TWS 5 10 15 20 25 30 TWA offset -5 -2 3 5 6 7 +/- some degrees As course (not heading) is used for TWA and leeway is a factor in course, make sure you have your heeling sensor and leeway constant calibrated (along with your compass of course) before you go for tweaking your TWA any further.

    Pilot calibration secrets (B&G H5000)

    Still what I’m after is not numbers - it’s what to look for and how to adjust - I’m not lacking hours on the water ... but I just don’t know where to start - my boat seam to be very active on the helm and snaking more than it would stealing by hand - where do I start? Response - rudder gain - counter rudder? What’s your scheme of adjustment? Look for what - adjust what?

    @BobJ as this is for IMOCA 60 it’s not for us, but there is some useful info in here if you haven’t read it https://www.blur.se/images/H5000-Pilot-Advanced-User-Info.pdf

    Pilot calibration secrets (B&G H5000)

    @BobJ my boat is a Prima 38, 38ft, 6500kg with an L shaped fairly wide bulb keel and a fairly large spade rudder - but if you let go of the helm, she will find her own destination on the chart and turn to it very quickly. I think my drive is the T1. Pilot obviously H5000. I’m happy to share my settings but I doubt they are much help - I’ll check when I’m back In the boat.
  11. I keep reading about how the top solo sailors have an intimate relationship with their autopilots which would most likely make their wives ask them to reprioritize their time if they knew. I’m reading article after article telling me how to master the pilot, however they all seam to start with the basics and tell me very little about the advanced functions and settings in the end. Can anyone share some of their secrets to better pilot performance? Rudder gain & Counter rudder and tricks for fine tuning? Do you set it once and leave it or do you keep making changes? I’m sure there is much room for improvement from my first commissioning – but what should I look for to fine tune? Auto trim – I keep reading about auto trim to keep a balanced weather helm, but I can’t find a way to change the auto trim in the H5000 pilot (or the manual), is there something I’m missing? If you know where to find it, how do think around adjusting it? Response – how do think on response in different conditions Gust respons – do you turn it on, if so what decides the min value, response rate and TWA window? TWS respons – do you turn it on, if so what decides the response rate? Bear away max – how do you come up with the right angle? Auto response – do you let the pilot handle response by choosing Economy, Normal or Sport, if so when do you go eco and when do you go sport? Or do you prefer to set your own response rate? Recovery – do you turn it on? What are your thoughts on narrow/medium/wide? Heel compensation – Do you turn it on, if so how do you decide on response rate? Tack time & tack angle – do you change it? How do you come up with the numbers? What else am I missing? What are key settings for success and what can be left to default?

    NMEA2000 to Fastnet (B&G) converter?

    Thanks - I reached out to Tinley a couple of years ago, by then they couldn't help me, I tried again last week, but still havn't had an answer.

    NMEA2000 to Fastnet (B&G) converter?

    Thanks, I think our needs are slightly different. From what I understand you´re running H2000 as you main instrument system and you’re trying to complement it with additional data. I’m trying to scrap my H2000 processor and go to H5000. All I’d like to keep is my three mast 2020 displays. They work just fine and getting three N2K ones is £2,100 I’d like to spend on more crucial parts as a full H5000 Hercules installation will be a very expensive upgrade no matter what. I do have the a NMEA FFD as well as a Performance processor which according to the manual should primarily be used for NMEA input if available. But I thought they both required me to keep running the main processor for the H2000 system. Do you say an NMEA input to the FFD could be wired directly to the 2020s with no main processor? I thought contrary the manual stated that an NMEA input to the FFD might very well only show on the NMEA FFD. From the manual I read ... "A NMEA Full Function Display (FFD) can be used to interface NMEA 0183 data to a Hercules system. The Performance Processor can also be used as an interface for NMEA 0183 data to the Hercules System. The Performance Processor has two NMEA inputs and outputs, (one of which is disabled if the RS232C interface is required). In the case of multiple NMEA inputs and outputs it should not be assumed that data input to one device will be available for output from any other device,. E.g. Inputting Latitude and Longitude to the NMEA FFD will not ensure it is output from the performance unit. If the Performance Processor is installed on the system it should be used as the primary NMEA input." My "best case scenario" would be to scrap everything but my three 2020 displays. Apart from the extra power consumed from running both H2000 and H5000 I'm worried I have to bother with multiple calibration values for both H5000 and H2000 for TWD/TWA for example. But perhaps I can set H5000 to send calibrated values and set H2000 to read them with no further calibration. The “B&G H5000 Fastnet Interface” reversed would be ideal – but NMEA0183 to Fastnet would be fine as I can easily go from N2K to 0183. As Sailmon processors take N2K input and output Fastnet to old B&G displays – I’m looking for the exact same function but without paying for all the extra benefits of a Sailmon processor.

    NMEA2000 to Fastnet (B&G) converter?

    The displays do not take NMEA0183 as far as I know - the old H2000 performance processor should be able to take NMEA0183 but I'm not sure which sentences it would accept. Also I would prefer tu run only one processor and remove the old H2000 and H2000 performance processor completely if possible.

    NMEA2000 to Fastnet (B&G) converter?

    Thanks I have it, but it's only a one-way converter so I can use it to get N2K fram a Fastnet processor (in my case into expedition) but not to get Fastnet out of a N2K processor which would be the case if I bought the H5000 processor and kept my old Fastnet 20/20 displays.
