Configuration Overview
All configuration settings are organized as key-value pairs where the key is a string
and the value either a string, a number (integer or real), or a hexadecimal number
represented as string. The key is not case-sensitive. The applicable range of valid
values depends on the key and the target device. While most items can be both
written and read, some are read-only (e.g. the serial number). Not all items are
valid on all devices; e.g. if a transponder receiver is not present, the PCAS settings
are invalid.
The canonical format to set and request configuration settings is the $PFLAC format
as described in FTD-12 FLARM Data Port Specification. In short, the format to set
a configuration is:
> $PFLAC,S,<key>,<value>\r\n
$PFLAC,A,<key>,<value>*XX\r\n
Where XX is the checksum according to the NMEA 0183 standard, "\r\n" the
newline sequence as used on Windows operating systems (0x0D0A) and ">"
denotes the user input and is not part of the format. To request the current setting,
issue:
> $PFLAC,R,<key>\r\n
$PFLAC,A,<key>,<current value>*XX\r\n
On most FLARM devices, the $PFLAC format can be applied either on one of the
serial ports or by means of a configuration file on the attached mass storage (SD
card, USB) drive. Refer to the installation and operating manuals of the respective
products for further details.
The value type and range for each item is specified separately. Values outside the
given range should be ignored. The following naming is used:

Integer: number which is written without a fractional component

Fixed point: real number with a fixed number of digits after the radix point
(dot)

Decimal: number which has ten as its base (e.g. 123)

Hexadecimal: integer number which has sixteen as its base (e.g. AF)

String: a sequence of ASCII characters without NULL at the end

Floating point: real number with an arbitrary number of digits (within limits
as specified) after the radix point (dot)

3.1.1
ID
Description:
Read or set the ICAO 24-bit aircraft address which uniquely identifies the device.
The ID cannot be changed when airborne, i.e. when moving. This is part of the
radio broadcast data. Devices with identical IDs (intentional or by accident) will
not see each other, thus do not enter any other value than your ICAO 24-bit
address. The ICAO 24-bit address is available in the aircraft registration
documents, and/or on the website of the local aircraft registration authority. If you
are not sure what your ICAO 24-bit address is, set it to FFFFFF for automatic mode.
In automatic mode, the ID is related to the serial number of the device. This 24bit number is built up similarly to the ICAO aircraft address system described in
chapter 9 of ICAO Annex 10 Volume III.
Devices:
All
Values:
One of the below values is possible:

Description

value

address.
Never set a value if not certain.

installed.

NMEAOUT (NMEAOUT1, NMEAOUT2)
Description:
Configure which sentences are sent by FLARM on the data ports. Do not change
this setting unless really required, as multiple devices may be connected to the
same port.
As specified in the table, adding 40, 60 or 70 to <value> selects the protocol
version.
NMEAOUT configures the data port on which the command is received. Additionally,
devices with two data ports introduce items NMEAOUT1 and NMEAOUT2. These items
work like NMEAOUT but configure a specific data port (No. 1 or No. 2).

3.1.3
BAUD (BAUD1, BAUD2)
Description:
Sets the baud rate of the data 1 and extension port. FLARM will first send the
acknowledge sentence, and then switch immediately to the new rate. Note that
when this sentence is used on an SD card or USB stick, the baud rate is changed
only after restart. The value is not saved for the extension port and is restored to
4.8 kBaud after restart.
On devices with two serial ports, the items BAUD1 and BAUD2 are introduced to set
each port specifically. These items work like BAUD but configure a specific data port
(No. 1 or No. 2).
Devices:
All

57.6 kBaud
Note that the standard NMEA 0183 baud rate is only 4.8 kBaud. Nevertheless a lot of
NMEA-compatible devices can properly work with higher transmission speeds, especially
at 9.6 and 19.2 kBaud. As any sentence can consist of 82 characters maximum with 10 bit
each (including start and stop bit), any sentence might take up to 171 ms (at 4.8k Baud),
85 ms (at 9.6 kBaud) or 43 ms (at 19.2 kBaud). This limits the overall channel capacity to
5 sentences per second (at 4.8k Baud), 11 msg/s (at 9.6 kBaud) or 23 msg/s (at 19.2
kBaud). If too many sentences are produced with regard to the available transmission
speed, some sentences might be lost or truncated.

ACFT
Description:
Configures the aircraft type used by FLARM. This setting will affect the internal
algorithms, as FLARM’s motion prediction is aircraft type specific. This is also part
of the broadcast data. The aircraft type configuration in FLARM must be set
appropriately for tug / tow planes. The setting “tow / tug plane” results in a
different warning behavior for gliders as long as a glider being towed is detected.
Warning: Contrary to the hexadecimal convention in PFLAA, the aircraft type is
given as a decimal value here.

PRIV
Description:
Stealth mode. Instructs all receiving FLARM devices that the received data must
not be made accessible in real-time full precision, except for the purpose of
collision warning. Real-time is understood to be within less than 10 minutes. With
the option set, not all information is forwarded to connected displays to prevent
abuse in competitions. An activated stealth mode results in PFLAA sentences not
carrying specific climb and cruise data while some random noise is applied to
altitude data. It is recommended NOT to activate stealth mode! To apply full
reciprocity, a pilot who enables stealth mode will only get information as if all other
aircraft had enabled stealth mode, independent of their actual setting.
The status and changes to the stealth mode are recorded in the IGC file.
Consequently, a competition authority can easily enforce the use (or non-use) if
desirable. The table below presents the limitations in PFLAA sentences when stealth
mode is enabled.
Stealth mode cannot be changed during flight.

Description:
Sets speed threshold in m/sec below which the aircraft is treated as "on ground".

aircraft. This setting is automatically changed to default every time the ACFT value
is changed. Normally there is no reason to set THRE manually.

3.1.10
LOGINT
Description:
The value indicates the time interval in seconds between two data points in the
flight recording. The longer the time interval is between two data points, the lower
is the resolution of the recorded flight. For gliders and when a high resolution is
required, do not use settings higher than 4s. FLARM should not be switched off
immediately after landing to ensure that the whole flight is recorded.
The interval between two data points affects the recording capacity in terms of
flight duration. The memory in FLARM devices is shared between the obstacle
database and the flight recorder.
Devices:
All
Values:
Decimal integer values from 1 to 8 are possible.
