R-DAS I2C Bus

[Bernt-Johan Bergshaven]

Hello

I'm currently working with a student rocket, and inside this rocket we
want to use a data collector with a telemeric sender. This is a
commercial product called, R-DAS. (see
http://home.iae.nl/users/aed/rdas/ ). Available for to this r-das is
several addon modules, including a GPS sender. All theese modules use
an I2C bus to communicate with the moder board which sends the data to
the ground. I want to use my own GSP sender and make a board to
communicate with the moderboard. I'll be using a AVR uC.

My problem is that the company producing R-DAS won't give me any
information regarding the protocols used in communication with the
moder board, nor any adresses on the bus.

My question to you is if there are anyone out there with such
information, or if there are anyone with good ideas on how I can
figure this out by measurment or testing?

If there are anyone who would like to reply to my mail, rather than
posting on this group; bernt(remove this)@netbase.no .

Thank you
Regards
Bernt-Johan Bergshaven

Can't help you on the R-DAS but if you get anywhere please let us all know,
I know there are several other people who would like this info.

As an alternative have you looked at the OZARK ARTS altimeter?

http://lokiresearch.com/arts.asp

It has an interface an RS232 NMEA2.0 GPS interface and a well documented TTL
serial interface for external modules to receive flight data and events.
There should telemetry module on the way.

There is a RDAS group on Topica. Join the list and search for "Protocol".
You will find the answer to your question. And yes it was answered by AED.
Not using the I2C bus but the serial side of the transmitter. Good
luck.....
