Has anybody yet looked into the Zander Data Format e.g. between SD1 and GP941?
Baudrate, Voltage Levels, Format and so on

Thank you. But thats the Data format of the NMEA output. - its good to have them too...
But there ist a different Data Format on older GPS Moduls on the SR-TX and SR-RX pins.
And I dont know wether they are on RS232 level or not!

the best could be to ask to Zander or to SDI

Finally I got it working.
I can use the GPS-Position from Flarm and supply this coordinates to a Zander 820, 940 or ZS1.
No need für Almanach or Time settings while booting and off course no 1000week problem.
I use the circuit from alphalima with a level shifter to 5V TTL.
One channel is blocked for this.
The other two can still be used for LK8000 or xcSoar Wifi.

You could make a setup like this:

COM0 - only output GPS-Zander - 9600 Baud
COM1 - Flarm Data 19200 Baud+Wifi
COM2 - 9600 Baud for COM + Wifi ( + GPS-Position for a ELT. This is on the TX line only and just sending the Pos to the ELT)

So the GPS Position with 19200 Baud has to be transfered to 9600 Baud to fit for Zander and ELT. For Wifi you need 19200 to get the postitions of the other aircraft.

Unclear so far is, if the Zander-windcalculation will be all right with the Positions form FLARM. There is a little timeshift as there is a lot of calculation to translate NMEA to Zander-"language".
Nothing tested on the Plane jet. Will be put into the plane in Winter.
If anybody else would like to test it as well, send me a PN.
