![]() #Macenc nmea 2000 serialIf one is feeding NMEA data from GPS, AIS, Instruments all into the GPS Panel serial port via a multiplexer then it is the job of the multiplexer to handle prioritizing the NMEA data. "Autopilot Only" limits the "Repeat" serial port to only manufactured NMEA data when a waypoint is active. So the GPS panel Settings could have the option to "only repeat processed" NMEA data, but then that would limit it to sending out only GPS NMEA data and all other would be filtered out. It does not repeat the AIS/RADAR nor Instruments NMEA data from their respective serial ports. On the other hand, the GPS Panel repeat serial port only repeats what comes in on the GPS Panel serial port. The "TCP/IP Server" takes the NMEA data input from the three serial ports (GPS, AIS/RADAR and Instruments) and consolidates them into one output NMEA data stream on a single TCP/IP port which is then sent to any connected client. Just to clarify the "Repeat" serial port works a bit differerent then the TCP/IP server. Two copies of sentences with different data in the same stream would confuse the receiving systems. Usually this means getting NMEA data from two or more streams – one for GPS, Route, Waypoint etc, related data and one for instrument data but the instrument stream can contain GPS sentences with incomplete data. This is because the information in the NMEA sentences vary (so does the sentences generated) depends on which RM device is used to convert the Seatalk to NMEA. Only consolidate the “good” (cause a “green dot” display) sentences from an input stream into the TCP/IP stream.Įither would be required to make TCP/IP workable in a Raymarine systems configuration. ![]() Provide for preference selection of which sentence from an NMEA input stream gets consolidated into the TCP/IP stream.ī. There are at least two possible approaches.Ī. ![]() ( ³) Controller Area Network : standard bus developed by Intel and Bosch and selected by NMEA 2000.Is the plan to consolidate all NMEA data received by MacENC into the TCP/IP stream without modification? It would be of benefit (IMHO) to have some control over which NMEA sentences gets consolidated into the TCP/IP stream. #Macenc nmea 2000 driver( ²) Its driver for OS X is available FTDI V.2.02.17 on the manufacturer's website.
