Abstract
Disclosed is a security device for selectively isolating an electronic device from external data signals, including an input for receiving an external cable, an output for connecting to the electronic device, a configuration line coupled from the input to the output, a power line coupled from the input to the output, a ground line coupled from the input to the output, a plurality of data lines, and a first switch selectively coupling the data lines from the input to the output. The security device can further include a filter in the configuration line where the filter configured to receive an encoded message, compare the encoded message against a messaging specification, and selectively transmit the encoded message when the encoded message complies with the specification.
