3.5 Addressing
You use addressing commands to manage the short address of the devices.
3.5.1 Start scan and assign short address
Description
Use this CM command to scan the physical devices on the DALI bus and assign ran-
dom short addresses to the devices that have no short addresses or conflicted short
addresses.
This CM command changes the random address of devices:
• If the device has a short address that is unique on the DALI bus, the device keeps
its short address.
• If the device does not have a short address or its short address is the same as
another short address, CM 1xDALI assigns a new short address to it.
If there are more than 64 devices of the same type on the DALI bus, you get the error
"16#87 (not supported)" in the response parameters.
This command returns 16#01(In progress) when it starts a progress of scanning.
You can check the process of scanning by "querying the current command status
(Page 49)" or stop scanning by "canceling the current command (Page 51)".
