13 Network connectors (RGB 474xi xi xi xi xi) — Connect a computer to this
RJ-45 female connector for pass-through to a network.
14 Opening for Architectural Adapter Plates — The RGB 478xi can
accept up to four optional standard architectural adapter plates
(AAPs) attached here. The RGB 478 Mxi (not pictured) can
accept up to four optional mini architectural adapter plates
(MAAPs) attached here. The adapter plates come with a variety
of audio/video connectors.
Blank plates (two single-space and one double-space) are
included with the interfaces to cover unused spaces. Adapter
plates must be ordered separately (see “Optional Adapter
Plates” in appendix A). They must also be attached to the
faceplate and cabled before the interface is installed in the wall
or furniture. The screws needed for installing the adapter plates
are supplied (MAAPs), or built into the plates (AAPs), so no
additional screws will be needed.
Euro Channel versions
The RGB 472xi, and RGB 478xi are available in a Euro Channel
(EC) version and the RGB 472xi is also available in two floorbox
models (MK and FSR) (see appendix A for part numbers).
The front and rear panel features, cabling requirements, and
testing/troubleshooting procedures are identical to the
descriptions shown in this chapter for the wall box models. For
installation instructions, see the RGB 470xi Series installation
guide that addresses your specific requirements.
