I'm trying to connect an expansion unit to the SMARTDAC+ GX/GP. Can you give me instructions?

First, install the expansion module into slot 9 (GX20/GP20) or slot 2 (GX10/GP10). Turn the power to the GX/GP main unit and the expansion module OFF before inserting the expansion module into the GX/GP, and before setting dip switches. For details, see "Installation and Wiring" in the first step guide (IM 04L51B01-02EN).
