D-Sub De9: Power, Data And Audio Connections - FLARM PowerFLARM Core Installation Manual

Pin 5 transmits NMEA-0183 Version 2.0 data at a configured data
rate (default is 19.2kBaud). Further FLARM-specific data is availa-
ble for periphery devices (e.g. remote display).
Do not connect more than one external application to the port.
Maximum current on pin 3: 200mA @ 3VDC.
The 9 pin DE9 connector is shown below. On the left side the female

Pin 2 transmits NMEA-0183 Version 2.0 data at a configured data
rate (default is 19.2kBaud). Further FLARM-specific data is availa-
ble for periphery devices (e.g. remote displays).
Do not connect more than one external application to the RS232
port.
Maximum current on pin 9: 200mA @ 3VDC; independent of pin 3
of the RJ45 connector.
