Sub Device and Personality
Can each sub-device have a different set of personalities ?
This would mean that - Each sub-device can be set to a different personality - Each sub-device can have a different footprint When I read the RDM standard I think the answer is YES, however in the book CONTROL FREAK, Wayne Howell answers the question with NO(page 110). When the answers is YES, the controller has to find each sub-device and read the device info to get the current personality/start address/footprint(or use the specific pid to get the value). It is however difficult to find the sub-devices because the id's must not be continues. The device info tells only how many sub-devices there are, not there id's. So I would expect that there exists a pid GET_SUPPORTED_SUBDEVICE_IDS (like SUPPORTED_PARAMETERS), but this is not the case. Regards, Kurt |
