Ok, I don't.  But I did find a genuine 2382W and popped it open.  It
uses the two-diode scheme described above.  There is also a 33k series
resistor (which is probably in the others and I just forgot).

| The original slaves that I describe above had the LED on all the time; it

The LED in this 2382W is across the line with a series diode and pair
of dropping resistors.  So it would be on all the time and the text on
SmartHome's page is probably just a mistake.

So, if the 1135 is something completely different then you can always
get a PCS of Lightolier slave.  Otherwise maybe there is a wiring problem.
