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.
Updated 2018-02-01 ! To test Openplotter, (OP), together with OpenCPN,(OC), without connecting to the navigation network on board there are two features
Using the NMEA generators, found in the OP "Tools" menu
Use log files which are stored within the SignalK application.
The generators are explained in the documentation and here will be a description how to use the log files from OP Connect to the Rpi. As said before SignalK, SK, is the engine in OP so we start with terminating that process so we can redirect SK to the log files. Open a Terminal window "Application menu => Accessories => Terminal" and type pkill -f signalk-server
It comes with NOOBS(New Out Of Box Software) which makes it very simple to install
Its also a compilation of several other nice software which makes it a fantastic package for additional functions.
The Openplotter WEB-site, the nice forum with active people and god documentation makes it almost easy, but if You are a newbie to both OpenPlotter(OP) and OpenCPN(OC), as I was, it can be to much.....
Updated 2018-02-14 ! This backup method will make a copy/image of the whole card even if there is very little data on it. So if the card is 16Gb, the backup file also will be 16Gb. On the other hand You can ZIP the image file to save space. Another, maybe smarter ?, backup method is described here. Connect the card reader, with the SD card inserted, to Your Mac.
Start the program Terminal, on Your Mac, and check Your SD cards name type.
$ diskutil list
and You will have something like
