RDM proxy RDM 代理裝置
An RDM device that responds on behalf of others, holding a list of the UIDs behind it so a controller can be handed that list rather than discovering through it. Typically a gateway onto a segment that does not speak RDM, or a system with its own internal bus. Devices behind a proxy appear in the patch as ordinary devices.

代其他裝置回應的 RDM 裝置，內部保存其後方裝置的 UID 清單，控制器可直接取得該清 單，而毋須穿透它進行搜尋。通常是通往不支援 RDM 網段的閘道器，或本身具備內部匯流排的 系統。代理後方的裝置在配接表中會如同一般裝置般出現。

Easy to get wrong
A UID on your line need not be a device on your line. Behind a proxy it may sit on another bus entirely, which is confusing when you go looking for it.
