If the LM465 is Off, then any Dim command will first turn it fully
On, then proceed to Dim it from that point.  This is a firmware
feature of the LM465 and cannot be changed.  Was that your
question?

If the LM465 is On but fully dimmed (to darkness), then it can be
brightened with the appropriate Bright command.  Or if partially
dimmed it can be further dimmed or brightened from that point.

I don't know what algorithm your SDM3 uses to convert the
programmed level (e.g., 30) to the (nominal) 210 brightness steps
available in the LM465 - you may have to experiment.

BTW, alt.home.automation doesn't get a lot of traffic - you'll be
better off posting to comp.home.automation.
