Theft of boat electronics seems to be a continuing problem. I
remember there was a series of break-ins in Scituate, MA years ago
where chart plotters, radios, etc., were stolen. They would simply
unplug or cut and leave the cables because they were too difficult to
remove quickly so they just took the electronic units.
Seems to me that will all of the advanced electronics available today
that a digital "key" could be programmed into the cable itself thus
making the electronic unit inoperable without the proper cable
connected. Something similar is done with a popular recording
software package called "Pro-Tools" in the music industry. It's
purpose is to prevent pirating of the software for use on other
computers, but the device has to be installed in the interconnecting
cable in order for the computer containing the software package to
communicate with anything else. You can run the software without the
key but it's useless because there's no data input available.
