Abstract
An interface for serial data transmission between a hearing aid and a control device has a first data terminal for bi-directional data transmission to and from the hearing aid, a second data terminal for receiving a data format containing a start bit from the control device, and a third data terminal for data to be received by the control device, plus at least one coupler for data transmission from the second terminal to the first data terminal and at least one coupler for data transmission from the first data terminal to the third data terminal. The two couplers have an interactive (shared) connection which is normally placed at a first logic level, but which can be modified to a second logic level by signals either from the control device or from the hearing aid. The logic level at which the interactive connection is set determines which path data will be transmitted between respective terminals.
