RDM Proxy devices

[Vinayakadj]

Thanks Scott for your reply. I have few more question which really helps me.
1. What would be the source Id for the response generated by Proxied device?. As the message is generated by Proxy should the source ID be Proxy's source ID or it should be the source ID of Proxied device.
2. This question is regarding Binding UID field and Port ID. As per my understanding
If one physical device has multiple logical devices we can bind UID to it. Can you explain me the difference between using a binding UID vs Proxy device? In my implementation of hardware, we have a physical device with multiple logical devices associated with it. Should I choose Binding UID and represent them as the single physical device or should I use Proxy to represent them?

Regards,
Vinayaka D J

The source address should be the UID of the proxied device.

The binding UID is used when you have a responder with multiple DMX input connectors.



Proxy is used when you have multiple *logical* devices behind a single DMX input connector.



For example, a dimmer rack that has two DMX inputs would use the Binding UID to tell the controller that those two different UIDs are both connected to the same rack. Without this, the controller would believe it's seeing two different dimmer racks.


A color scroller system with a power supply and 8 scrollers would use proxy because you want to controller to recognize it as 9 separate things.

No. The Port ID field gives the *controller* port number and only exists in an RDM request. If the controller has multiple outputs it lets you determine which output generated the request.



The Binding UID is used by*responders* to give information to the controller.
