J3 – Auxiliary Port
J3 is a 26 pin female mini-D ribbon connector (AMP 2-178238-4). It
duplicates the first 26 pins of J1, the Controller connector, which are
discussed in detail beginning on page 6-1. Contact between the
connector shell and the grounded chassis provides shield termination.
Allen-Bradley cables are available in various lengths for connecting
between J3 and an auxiliary unit. “Options and Accessories” on
page A-1 lists the cables that are available.
