Installation / Operation Manual
anemoi
-
The RJ45 connector has the standard IGC pinout, however only the pins Rx (
anemoi
receives
data) and GND are actively used.
anemoi
does not supply or consume power nor send data
(Tx) via the NMEA RJ45 connector.
-
If
anemoi
is operated in parallel with other devices on the RS-232 NMEA bus, a 1:1 Y-
Adapter can be used to split the signal. The P/N of the 1:1 Y-Adapter is listed in Table 3-2. As
anemoi
merely receives but does not send data on the Tx line, it is not required to detach
the Tx line from
anemoi
to avoid multiple devices sending on the same line.
-
Make sure that the NMEA sentence
“
GPRMC
”
(standard navigation data) is included in the
output of the source device. In most cases no action is actively required to ensure sending of
this sentence, as it is the most fundamental content in the NMEA protocol.
-
The Baud rate of the RS-232 NMEA data stream must be one of the following: 9600, 19200,
38400, 57600, 115200 bps. If this is the case,
anemoi
will automatically adjust to the correct
Baud rate.
The extended pin allocation of the RJ45 GPS NMEA connector is shown in Table 5-3. A picture with
the pin numbering is shown in Figure 5-3.
