The 50 foot (15m) (IC693CBL302) cable has a single male connector on the CPU baseplate end and a single terminated male connector on the expansion baseplate end. The 3 foot cable (IC693CBL300) can also be used as a WYE adapter cable to simplify building custom length cables (see the section “Cable Application Suggestions” later in this Chapter). a43853 .5, 3, 6, 26 FOOT CABLES 50 FOOT CABLE FEMALE CONNECTOR MALE CONNECTOR MALE CONNECTOR MALE CONNECTOR MALE CONNECTOR A B Figure B-1.
