ABSTRACT:
An adapter for a data transmission or communication system, has a body with a longitudinal axis. Longitudinal ends of the body define coaxial openings. One plug is receivable in one opening. Another plug is receivable in the other opening in at least two positions angularly offset relative to one another about the longitudinal axis of the body. Placement of the other plug in the different positions results in a polarity reversal of the system.
