Re: RS485/NMEA0183 Connection to Simrad AT10

In a previous post you wondered: "Whether RS-485 can be directly connected to NMEA-0183 is unknown to me." It is appearing that the answer is that it can't be. That's why I ordered the converter. I have reset the baud rate of the Calypso to 4800, and the software confirmed that the configu...

Re: RS485/NMEA0183 Connection to Simrad AT10

I think I am going to need an RS485 to RS422 converter. A company called SerialComm makes a convertor. An RS485 (2-wire) input then converted to RS422 (4-wire). I have ordered this model: https://www.serialcomm.com/serial_rs232_converters/rs232_rs485_rs422_data_repeaters/rs232_to_rs485_rs422_or_repe...

Re: RS485/NMEA0183 Connection to Simrad AT10

So we know that we can get the NMEA 0183 MWV sentence INTO the USB port of the laptop using the little Letotech RS485/USB converter; if I could find a PC program that would see that incoming sentence and transmit it OUT on another USB port, I could connect the bare wire end of that USB cable to the ...

Re: RS485/NMEA0183 Connection to Simrad AT10

Jim, I tried those connections at the boat and still no data I looked at the "Technical Data" sheet for the anemometer and it says the data format is "RS485", but it doesn't mention NMEA 0183 anywhere. Is there some kind of conversion that takes place to make it 0183? Remember th...

Re: RS485/NMEA0183 Connection to Simrad AT10

The reason I didn't order the gateway from Calypso that you referenced is that 1) it's about $400, and 2) they don't have any availability until December. Additionally, I already had the AT10, and it says it does support translation of MWV. The Calypso is configured using what they call their "...

Re: RS485/NMEA0183 Connection to Simrad AT10

Thank you Jim, but I went over to the boat and connected as you noted, and I still see no MWV on the N2K network. And although the AT10 shows up when I run NMEA Reader on the laptop, if I go to my Simrad autopilot and run a search for sources, the AT10 does not show up as a source for "Apparent...

RS485/NMEA0183 Connection to Simrad AT10

Hello, New member in this Forum, longtime Bowers Harbor sailor and electronics enthusiast. I have done most of the wiring aboard Indigo, an Island Packet 37, but a recently installed Calypso Ultra Low Power Wired Anemometer is giving me fits. I cannot figure out how to connect the Calypso cable to t...
