What I did was putting my computer with a serial interface behind and
watched the data stream coming (on putty, it's NMEA 183) so I could see,
that the data was valid, if the ACK ELT can handle it correctly is
another question and I could not find out. Do not forget as well to have
the correct baud rate selected via the jumper inside!
Cheers

Spray-on batteries
Researchers at Rice University in Houston have developed a prototype spray-on battery
that could allow engineers to rethink the way portable electronics are
designed.The rechargeable battery boasts similar electrical characteristics to
the lithium ion batteries that power almost every mobile gadget, but it can be
applied in layers to almost any surface with a conventional airbrush, said Neelam
Singh, a Rice University graduate student who led a team working on the
technology for more than a year.Current lithium ion batteries are almost all variations
on the same basic form: an inflexible block with electrodes at one end.
Because they cannot easily be shaped, they sometimes restrict designers, particularly
when it comes to small gadgets with curved surfaces, but the Rice
prototypes could change that. "Today, we only have a few form factors of batteries,
but this battery can be fabricated to fill the space available," said Singh.The
battery is sprayed on in five layers: two current collectors sandwich
a cathode, a polymer separator and an anode. The result is a battery that can
be sprayed on to plastics, metal and ceramics.The researchers are hoping to attract
interest from electronics companies, which Singh estimates could put it
into production relatively easily. "Airburshing technology is well-established.
At an industrial level it could be done very fast," she said.
