RC4Magic Series 3 DMXio User ManualPage 14ID2ID2 is selected if the ID2 button is held during power-up.ID3 PublicID3 is selected if the ID3 button is held during power-up. ID3 is the Public ID and is thesame on all RC4Magic Series 2 and Series 3 devices every built. This allows devices fromdifferent systems, owned by different people, to be used together.The Public ID is also used when initially setting up RC4MagicPC with a remote controldongle. Until your computer has connected to one of your devices and learned your uniquesystem IDs, it does not know what they. After learning, RC4MagicPC software securelystores them on your PC.RC4 CodeLoader EnableThe RC4 CodeLoader is resident in every RC4 Series 3 device and is carefully protected. It isenabled by holding the Func/Shift button during power-up. Then, if CodeLoading does notbeing within 5 seconds, the DMXio reverts to normal operation.RC4 firmware files are encrypted before release, and decrypted by the CodeLoader, inside theDMXio. The RC4 CodeLoader also guards the device’s unique serial number and RDMaddress. (Every RDM device in the world must have its own unique address.) Updatingfirmware in your DMXio will never corrupt this important device-specific information.The RC4 CodeLoader facilitates firmware updating without corrupting user settings andconfigurations, provided the new firmware does not substantially change the range ofavailable settings and their ranges. In most cases, a firmware maintenance release can beinstalled without effecting DMX channels, curves, and other user or application settings.Connection to a host PC for CodeLoading is done with an RC4 Series 3 USB CodeLoaderCable. One end plugs into the DMX miniplug port on the Series 3 device, the other endplugs into a USB port on the PC.The RC4 CodeLoader application runs natively on Microsoft Windows. With appropriatelibraries it can also run on Apple Mac OSX, and most flavors of Linux. All you need is aworking PC, an Internet connection (to retrieve new RC4 code files), a USB port, and the RC4CodeLoader Cable.Single-Button FunctionsThe most commonly used DMXio functions are accessed with a single press of a singlebutton. All settings are saved in non-volatile memory and restored on subsequent power-ups.
