PARAMETER_DESCRIPTION data type semantics

[prwatE120]

Note :

2) I have a lamp here that returns a PARAMETER_DESCRIPTION response with a PDlen=2 and 0x0006 as the actual data. Did I miss something or is this just plain wrong ?

As Tim acknowledges, this could not have been a correct response to a GET:PARAMATER_DESCRIPTION, as the response must have a PDL in the range 0x14 -0x34, as detailed in section 10.4.2 of the standard.

Thus I found Scott's original response a bit misleading.

As has been documented elsewhere, the format of this PID is severely limited, and probably the best approach is just to use it to send a text description of your Manufacturer specific PID.
