The SignalK server(SK), the engine in OpenPlotter(OP) is coming with new releases pretty often and if You want to update, having used OpenPlotter RPI v0.10.0 NOOBS, the following instructions will help You.
TP-Link Deco is a smart Mesh system that extends Your WiFi. It is pretty easy to install but there is no direct information in the install app, Apple or Android, about how to interconnect the Decos with ethernet. Especially if You must keep the old Router. Connecting via ethernet is faster and more stable and also necessary if the Decos WiFi cant reach each other. Here is additional information how to set it up with a ethernet backhaul and if You must keep the existing router. Since it creates a separate network with the first installed Deco unit as a NEW router all the additional Decos must be connected to this first Deco. Nothing else !!
In a former post a I presented our approach to mix a modern NMEA 2000(N2) network with the older Raymarine ST 1 network, installed 2006. During the Years it has grown and been added with new functions. The pictures to the right is the actual layout. The first add on was a N2 GPS described here.
I have searched for a solution transmitting the NMEA data, from the navigation network, via WiFi, to for example iSailor or other Tablet applications. One way is OpenPlotter and another way could be SignalK(SK). Both applications use the Raspberry Pi(RPi). Both also uses SK as the "engine", but using just SK will give You the stripped version without additional software. If You want to buy a complete and ready hardware the iKommunicate(iK) will do the same job. It's also ships with both NMEA0183(N1) and NMEA2000(N2) interfaces and is N2 Certified. The admin user interface for setup of SK has really improved in the last time so it is pretty easy to setup.
I have got some questions which version we are using for the moment at the site vader.domsten.nu The version is from 2017-11-28 and You can get the whole site code from here. Please note that I have done some modifications so if You want the original code please rename
If You open the certificate file, with a simple text editor, it shall begin with "---- BEGIN CERTIFICATE ----" and end with "---- END CERTIFICATE ----" if it is the right format. The most simple way to load the cert, is to use "Method 1". Please note that You log in with the CLIENT, PC/Mac, user/password. Another method is "Method 3". In this example I will load Citrix Intermediate Certs to the SC-T25 from a USB stick.
This cost effective Thin Client is based on Raspberry Pi 3 and together with Stratodesk OS it is very versatile If You bought, or got, the thin ViewSonic client, VT, produced before date 2017-07, You can upgrade to the better Stratodesk NoTouch OS with out any cost. This OS is the "standard" OS for new devices. To get the software follow this link Here is the upgrade instructions. In Windows just follow the instructions in the link, but with Mac (or Linux) follow the instructions below.
Updated 2018-02-03 A very nice way to fix a backup is to make a copy, bootable, of the actual SD card You are using in the RPi and this when the RPi is up an running. You clone from the command line so You don't need the standard GUI, Pixel, and the SD card copy function. It is also possible to set up a cronjob, explained later, which for example makes a clone every night at 1 o'clock.
You just need a USB SD card reader, with a SD Card, which You initialize with the SD Formatter.
Then You plug the SD Card in to a free USB port on the RPi.
I like the Raspberry Pi, RPi, with Raspbian Lite (no Desktop is included), headless operation, and then adding the software You need. Until now I haven't had a use case where I needed a Desktop but now was time.
You maybe wonder, why don't use the Raspbian with Desktop ?? In that package there is a lot of software I don't need and I really want to optimize the RPi. I think that the less software You install the happier RPi will be. ;-)
So after some Googling inspired from this guide I came up with the following setup.
We bought a nice LED lamp, Nemo Ellisse Pendant Double, which was said to be dimmable, but when receiving it there was a big IF !!! The lamp was not "standard" dimmable, instead it was dimmable with 1-10 VDC or 100 Kohm potentiometer. The 1-10 VDC control is common in big installations, in public environment, since it can control a lot of lamps with one dimmer. Checking the lamp I found that the AC/DC LED driver was a Mean Well LPF-90Dand in the drivers specification the second IF was found !! The lowest control level didn't switch of the lamp
Updated 2017-08-14 Sometimes You want to "take home" Your latest trip on sea and "replay" it or replay it doing some changes in the settings for the OpenPlotter or OpenCPN applikation and se the result direct. One way is to create log files with the the "raw" NMEA data and then use them at home with tips from this post. Creating log files from NMEA 2000 bus, N2K, is the most straightforward. Check what name Your CAN usb interface have. One way doing it is reading the log from auto setup found in "OP=> Tools => Auto Setup" Open Terminal and just type the following with Your CAN usb name actisense-serial -r /dev/ttyUSB0 > N2K_2017-08-08.txt
Updated 2017-11-24 It's always nice to have ALL information at the same place, navigator/plotter, when You are out with the boat. What could be missing is the engine information/data. If You have a Volvo Penta from 2006 or later it could be pretty easy. Volvo Penta has it's own 22813366, 3889758 Raymarine ECI-100 Maretron J2K100
and so on. But there is a pretty new one from Yacth Devices, YD, which is OK priced, NMEA certified, having galvanic isolation between the interfaces and some additional features compared to the above mentioned.
If You started with my quick instal guide You are a little familiar with OpenPlotter, (OP), basics and now we proceed with the sensors. Don't forget to delete the RMC sentence from the "NMEA 0183 generator" which we used. In OP there is clever function that attempts to auto detect the connected USB devices This function auto starts until You uncheck the "setup autostart on every boot". If You want to start this manually it is found in OP=> Tools => Auto Setup. Please note that just USB serial devices will be listed. If You connect a SDR-USB for AIS reception it will not show in the "USB manager" because it s not a serial device. Read the log from auto setup and check what have happened and then open the "USB manager" tab. If the USB-devices don't show up but are found You have to add them manually according to the instructions.
