ID 3

Every RC4Magic device can use a Public ID, numeric code 999, which is the same on every RC4Magic system ever made.  The Public ID is sometimes identified as ID3 on device labels and in documentation — they are the same. Using the Public ID is the only way to use devices from different systems together.  No other wireless DMX system from any manufacturer provides the level of system security provided by RC4Magic private and unique System IDs — even with other RC4 users operating systems in the very same room, functional interference between separately coded systems is impossible.
