Abstract
A chassis for a television receiver is provided which is adapted to operate in cooperation with any one of a number of electrical subsystems which perform similar functions but have differing signal and power requirements, such as tuners, receiver controls, et cetera, and are located remote from the chassis within the receiver. Each subsystem is coupled to a connector by a cable. The connector includes a row of contacts located in symmetrically spaced holes in the connector. One of the holes is blocked and serves as a keying indication. Mounted on the chassis is a row of similarly symmetrically spaced terminals, with one terminal missing from the row. A connector can only be mated with the terminal row when the blocked hole in aligned with the missing terminal location.
