Hello,

I have built a pic- based datalogger with a RS232C interface for parameter
setting and data retrieving. Because the datalogger is used in seawater and
the quality of the connectors is sometimes a problem, I would like to use a
inductive interface to be able to communicate with the logger. This
interface must be very low power ( uA- range )and must be RS232C
compatible.
I have seen some advertisings about transponder systems (tags), which are
used in the barcode industry but I really don4t know if this is a solution.

Any comments, suggestions or links to homepages on this subject will be
appreciated.


Best Regards,
Thomas Fleckenstein
