RATU Installation

1. Insert the RATU (component side facing right) into the slot following the last station PCB.
Apply firm, even pressure to ensure proper mating of connectors (consoles will assume the
next four station port numbers). (See Worksheets in Chapter 4 – DK424 Configuration for
RATU slot assignment recommendations.
2. After installing the RATU, gently pull the PCB outward. If the connectors are properly mated,
a slight resistance is felt.
