Output GPS to DSC VHF - Leigh - 2017-12-01 Hi, I have a RPi3-Sensehat setup with a USB GPS (see bragboard) I'd now like to export GPS to my VHF radio (NAVMAN 7100EU) Page 36 in the manual in the link above says the Navman has GPS/NMEA input (I know this since at the moment I have the VHF wired up to an old Garmin Etrex) It also says Comm. Port: 4800 baud NMEA on page 36. How could I do this, physically and in terms of software setup Please Leigh RE: Output GPS to DSC VHF - Luckbert - 2017-12-01 look here https://sailoog.gitbooks.io/openplotter-documentation/content/en/nmea-0183-to-usb-converter.html RE: Output GPS to DSC VHF - Leigh - 2017-12-01 (2017-12-01, 08:57 PM)Luckbert Wrote: look here Thanks Luckbert, I put a notification request for when they come back in stock I found the NMEA add documentation, with both a GPS and a gpsd example button - what is the difference? RE: Output GPS to DSC VHF - Luckbert - 2017-12-01 Hi Gpsd is a deamon. It is a small tool between GPS sensor and software. GPS is the direct serial port. Greetings Jürgen RE: Output GPS to DSC VHF - Leigh - 2017-12-19 OK, so I have an NMEA 0183 to USB converter, but I'm not sure on the wiring. The NAVMAN 7100 DSC VHF installation guide shows the following GPS connections: 'Yellow: NMEA IN (+) from GPS' 'Green: NMEA IN (-) from GPS' The Etrex (that it is connected to the VHF at the moment) documentation says: 'White: Data Out' (and I have written a '+' on the page here, and this is connected to the yellow wire from the NAVMAN) 'Black: Ground' (and I have written a '-' on the page here, and this is connected to the green wire from the NAVMAN) I can't remember how I worked out that about the Etrex connections, but it works Now I want to replace the Etrex with the GPS out from the RPi Openplotter using the NMEA 0183 to USB converter. How would I connect it up? (a) NAVMAN Yellow (+) to NMEA 0183 to USB converter R+ NAVMAN Green (-) to NMEA 0183 to USB converter R- (b) NAVMAN Yellow (+) to NMEA 0183 to USB converter T+ NAVMAN Green (-) to NMEA 0183 to USB converter T- or (c ), something completely different? And, out of interest, what is the difference between 'T' & 'R'? After very short Googling, is T for 'Talker' (or simplistically 'Output') & R for 'Listener' (or simplistically 'Input')? I found this which seems helpful, and since I have only one GPS output and one GPS input I can just connect as per (b) above? Can anyone please confirm the connections I should make? Thanks |
