4. Connecting GP940 to PC:
Before the GP940 is used for flight data recording, personal information like name, type of glider and
so on should be entered into the recorder by PC.
The PC must be an IBM compatible Personal Computer (DOS 3.0 or higher, minimum 512 KB of
memory).
Connection between GP940 and PC is provided by program ZANxxE.EXE (xx = version number
00...99, E = English). To get this program, selfunpacking file GP940EN.EXE is copied from diskette to
a new, empty directory and started. Now several files are created together with ZANxxE.EXE. After
unpacking, GP940EN.EXE may be deleted to save space on hard disk.
Now connect GP940 with the 9-pin extension cable to serial port COM1 at the PC. At GP940 use the
9-pin socket on the front plate besides the red light. The cable used for this is a standard extension
cable and is normally called monitor extension cable.
Important:
Use only a standard 9-pin extension cable between GP940 and PC!
The data cable used to connect SR940 to PC cannot be used!
During PC operation the GP940 power is supplied by the internal battery of the recorder. This battery
allows PC operation for about 2 hours. If this battery is empty, the charger or the power supply of the
glider can be used as well.
To enter personal information into the recorder, select FDR functions from the ZANxxE.EXE main
menue, then select write personal information.
The recorder will answer with an audio signal:
= PC operation active
Every two seconds the red light of the recorder shows:
... = PC operation active
Now you can enter name, type of glider and other information. To be sure, read back the information
you have entered.
To read flights, select FDR functions and then read flight data from the menue. On screen the
latest 10 recordings are shown. If the last line shows the flight which you want to read then press the
ENTER key. If you want to read an older flight then use CSR keys before pressing ENTER.
Flights can be read as often as you want. Flight data will only be deleted by new records after 40
hours of operation. Records which do not show takeoff and landing times are no flights; the recorder
was turned on on the ground and was turned off again before a flight occured.
Each flight read from GP940 is written into a file with extension *.ZAN . The file name consists of
date, FDR serial number and the flight number of the day:
67AZB251.ZAN means: 1996 / July / 10 / ZANDER / B25 / flight number 1
(numbering system: 1...9,A...Z)
To avoid that flight data files are changed later for cheating, there is a safety feature included in every
flight data file from GP940. At the end of the flight data there are some additional informations, which
are related to all flight data since the record starts. With a safety check the flight data are checked
