... sieht einfach aus. Ich denke, ich werde es mal versuchen. Schön, dass wir darüber gesprochen haben. Danke!
VT-02
6.4.11. RS-232 interfaces
All RS-232 interfaces require data at RS-232 level (no TTL level).
RS-232 RX-0 (NMEA input for ADS-B out)
Input for connecting a GPS for ADS-B purposes.
Connecting a GPS receiver providing the data shown below makes the VT-02 broadcasting it's current position with extended squitters. Minimum recommended NMEA sentences are $GPRMC, $GPGGA, $GPGSA. The required NMEA data baud rate is 4800 bps.
Skymap
SERIAL DATA FORMATS
The Skymap IIIC can output standard aviation RS232 data at 9600 baud or NMEA 0183 format RMC, GGA and RMB sentences at 4800 baud. The data output type is setup on Screen 35 Data Input/Output Setup and Test Screen.
NMEA 0183 Data Format
The serial format is 4800 baud, 8 data bits, 1 stop bit, no parity. Each sentence is followed by a checksum (*hh), carriage return (CR) and a line feed (LF). All three sentences are sent every two seconds.
