Abstract
A system for transmitting a plurality of independent data signals between two modules connected to a communication link is provided. The communication link may be a two lead wired connection. A first data signal may be transmitted in form of a differential signal over the communication link. A second data signal may be transmitted between both connected modules by adding the second data signal identically to both leads of the communication link. The second data signal references a ground potential which is common to both connected modules.
