For any of you that have built their MicroEncoder, just a note to advise that
their RS232 Serial data output format for II Morrow is not compatible with the
new UPS Aviation Technologies SL70 transponder. The reason why is just slightly
beyond my ability to describe...in any event, their grey code output to the
transponder works fine. RMI is sending out a new chip to me this week with an
additional format which is fully compatible with the SL70 for serial data
transfer.

However, the SL70 is not yet smart enough to pick only the altitude data from the
stream and pass along the rest to your GPS. You can send the grey code output
from the MicroEncoder to the transponder and use the encoder's serial port to
send serial data directly to the GPS...I suppose this might be considered a
workaround.
