The ICL (Inductive Coupled Link, sometimes refered to as SKCM, Sail Keyed Carrier Module) interface allows non contact serial communication with an instrument via the pulsed ac magnetic field of a simple coil of wire. It was designed to be used by an ROV or occupied submersible to talk or listen to an instrument deployed on the bottom without making a direct electrical contact. It can support half duplex bidirectional communication at any baud rate up to9600. It uses only about a microwatt while waiting for a signal. It works in air on deck as well as in water.
