The six outputs on the top card of the SYPMB 6D are switched outputs - they will not dim. The six outputs on the back circuit board are dimming outputs. They are numbered from top to bottom, 1 through 6. When combined with your module's address, you will get a dimmer relay address for each relay (i.e., if your module is addressed as 1, your dimmer relay addresses will be 101 through 106).
You may land your load on either the switched OR the dimmed output, but not both.
