Name and signature of official observer

Valid calibration table of flight data recorder altimeter

Flight data must be transferred to PC in presence of an official observer. Both ZAN and IGC files are
required for FAI flight validation. One diskette with both files is kept by the official observer, another
diskette is for the pilot.

IGC files created by Windows program WinGP cannot be used for FAI purposes anymore. Instead the
ZAN files created by WinGP must be converted to IGC format by the latest version of DOS program
CONV-ZAN.EXE.

7. NMEA Output:

The GP941 has two NMEA data outputs. These data can be used by some glider computers from
other manufacturers or by palm PCs with programs to show airspace or map information.

The NMEA data transmitted by GP941 are these:

$GPRMC, ...

RMC sentence with GPS data

$PZAN1,0123,ZAN1AA*cc

barometric altitude (meter) and serial number of GP941

One NMEA output is connected to pin 8 of the power supply connector. Via the data cable to the gli-
der computer this signal is brought to the instrument panel for further use. The GND connection is the
minus of the 12V power supply battery.

Another NMEA output is available at pin 2 of the PC connector during flight data recording. The same
pin is used for PC connection. Pin 5 of the PC connector is GND. So a palm PC serial cable can be
plugged directly into the PC connector of GP941 to use the NMEA signal.

A palm PC connected to the PC connector of GP940 can also be supplied with external power. Within
the GP941 there is a connection from pin 8 of the PC connector to pin 3 of the GP941 power supply
connector. Via the data cable from GP941 to SR940, a palm PC supply voltage can be brought to pin
3 of the power supply connector and from there to pin 8 of the PC connector.

So a palm PC connector to be plugged into the PC connector of GP941 should have these pin as-
signments:

Pin 2

RX-PC

Pin 5

GND
