2Touch 2150 series Installation Manual page 10

In the following diagram, power and connector requirements are identified for
these three zones. The diagram displays the combination of a 2Touch IWB,
the Epson EB450W projector, and the 2Touch 014 audio solution.
Note that the wall panel can be located on either side of the board, however
installers must be aware of the consequences of this decision on the length of
USB cabling from the board via the USB hub to the wall panel (typically, an
extra 2m USB extension cable will be required if the wall panel is positioned
on the right hand side of the board).
Note also that in the case of the 2Touch 015 audio solution being used, there
is no provision of USB ports on the front of the speakers. Therefore the
placement and connection of the USB hub is then entirely independent of the
audio solution, and the 2TAudio_015 speakers can be mounted completely
separately from the rest of the package, providing only for the relevant power
and audio feeds to that system. In these cases, the USB hub is most typically
secured behind the 2Touch board but at one edge, such that it can readily be
accessed for servicing purposes, and the hub is powered from a GPO typically
located behind the board or immediately below it.
The next diagram outlines the provision of cabling:
• VGA and other video cabling from the projector to the wall panel;
• Audio cabling from the audio solution to the wall panel, and between
the two speakers;
