Sub device field handling
I have a responder with no sub devices. If I receive a command from a controller such as GET_DMX_START_ADDRESS, but that command has a non-zero sub device field, I'm thinking I should respond with a NACK sub device out of range response. Is there another way to interpret this?

That is the correct interpretation in my view.
If a responder has no sub-devices, it should NACK any request that has a non-zero sub-device field. The NACK Reason Code should be NR_SUB_DEVICE_OUT_OF_RANGE |

Thanks Eric. I was just looking through the draft E1.20 document and I see that it clarifies this point and agrees with our interpretation.
