RDM
RDM is a two-way communications protocol built-into DMX512 for remotely controlling and configuring compatible fixtures. RDM is only active on the Patch screen. Any RDM-compatible fixtures will automatically appear in the patch list.
The RDM button enables and disables RDM on the local DMX ports and RDM messages coming from gateways to the console. When enabled, the RDM button will be green.
Note: You may also choose to turn off RDM when you have patched all the fixtures in a rig that you wish to use. If the patch list contains fixtures that you do not wish to patch, you can remove them by turning off RDM.
RDM via Network
RDM across a network connection from an ETC DMX/RDM Gateway to the device may also be enabled or disabled with the RDM button.
Note: Disabling RDM will not affect what gateways do on their respective DMX outputs. To configure RDM behavior on a particular gateway DMX output, use a network management tool such as ETC Net3 Concert, or the local controls of the gateway itself.
