Eos Family Software v2.3.1 and above can support up to 4 DMX output devices connected directly to a console or computer. DMX output devices include a local internal I/O card, ETC Gadget I, or a Programming Wing.
Gadget II and Programming Wings with 4 ports are also supported in subsequent Eos Family versions.
This is a limitation on the number of devices, not necessarily the number of DMX ports. A Gadget I (with one port) is counted the same as an internal I/O card (like a 4 port as used on a Gio@5).
A console (Ti, Gio, Ion, Element, Ion RPU, Eos RPU3) would support a maximum of three Gadget devices (1 internal I/O card plus 3 gadgets for a max of 4 DMX devices).
A PC or Mac running ETCnomad would support a maximum of four Gadgets. If a programming wing is connected (which has its own internal I/O card), a maximum of 3 Gadgets would be supported.
A single Gadget will work with Eos Family software v2.2.x on PCs and Macs.
Please note that the original Eos console does not support any external I/O devices such as Gadget or Eos Programming Wing.
Windows XPe devices (Eos, some Ions, some Elements, some RVIs, some RPUs) do not support Gadget II or Eos Programming Wing.
