What I can imagine: If anybody is intrestet in personalize or optimize the board I have no problems to send the grip files or the data. I work with kicad and eagle. Kicad is also open source. wow, that is even better to make a shared project. I remember studying that tool but just now I realized the potential. You can fork, control version, share, edit online... That is what we need thanks! RE: Server Hardware for openplotter? - glowntiger - 2019-09-06 Hi, today I have test a little bit with pgpio. For this I have connect the seatalk dataline to the IN4 (Optokoppler Input on GPIO20) connector. I have read the PGPIO Manuals. I do not found something for stop bit and so on. The Data I get with 9bit mode I don´t think right? Has anybody an Idear?

Or is it better to wait for the new version of the card?

There to much spezial problems to do this with the pi.... If anybody need this, I make an adapterboard with an microcontroller for seatalk <> nmea0183. There are several librarys for this. That by the way I can do as opensource.... ;-) RE: Server Hardware for openplotter? - Sailoog - 2019-09-13 (2019-09-09, 10:19 AM)glowntiger Wrote: I think I´ll let it be with the seatalk on the board. In my opinion if you make this in HAT format it will be quite successful.

Are there any news with the new correct card? RE: Server Hardware for openplotter? - glowntiger - 2019-09-13 I do this with a hat... At the Moment I recheck the NMEA0183 Ports. I get grey hairs… I have never seen something like this. Normaly nmea uses RS422 standard or asymetric RS232 Standard. Now I have tested a ST60+ Raymarine. This Display has a NMEA Output ( + /- ) normaly you expect that - is gnd or the B Port of the RS422. No. Raymarine ST60+ switch the ground Pin!! means + is always 12V. gnd is gnd and nothing happens. If you put the resistor (120Ohm) between, gnd is also 12V and on Data Moment switch to gnd. This isnt compatible to any Standard????? After searching in web I´m not the one who have this problem. Why somebody do such a sh**??? RE: Server Hardware for openplotter? - glowntiger - 2019-09-14 I have checked the NMEA Ports again with RS232 devices. works fine. With SA320 GPS Works fine. With Furuno RO4800 works fine. Except Raymarine ST60 all NMEA I have testet worked. Further I Have get a KUS NS5 Fuel Sensor. I have order them new for my boat. I have connected to the Board. (NMEA2000) Thats the Result: the PGN must be 127505. is in HEX 1F211 I think its correct in the shown data. Also the first 6 hex bytes is the fuel level. Thats seems correct. The rest works later direkt trough OP.

The NMEA output is balanced, i.e. the NMEA negative is not the ST60 negative. In the RS-422 communication, the transmitter operates the logical "1" at a voltage of -2 to -6 Volt. and the logical "0" at the receiver input in the range of +0.2 to +7 Volt. This means that the bit amplitude can be up to 13V. Using an RS485 should work, as it is compatible with RS422 but not the reverse. I've seen you try to read the SeaTalk sentences. I'm sure you know Thomas Knauf's work. He published some simple circuits to adapt the SeaTalk signal to RS422. This circuit is for unidiractional, e.g. read only. This other circuit is for bidirectional communication. |
