Pre-Wire
VIA! Touch Panels require power, control, status, and video connections to
function correctly.
• Control, Status, & Power:
Cat-5
• Video: RG-6 or RG-59 Coaxial Cable
Control, Status, Power
Run Cat-5 wire from the main equipment location (head-end) to the location
where the touch panel will be installed. Make sure that provisions have been
made for installation of a PVIA Wall Plate or Precision Panel (typically at the
head-end).
Video
VIA! Touch Panels have both a Video Input and a Video Loop Output for
composite video signals. Run RG-6 or RG-59 coaxial cable from the head-
end location (possibly a video switcher) to the location where the touch
panel will be installed. Be careful not to make sharp bends when installing
coax. F-to-RCA connectors will be necessary to adapt the RCA composite
output of the video source (or switcher) to the F-connector of the coax run
(see
Figure 3.7 ). The VIA!s have female F-connectors for both Video Input
and Loop Output.
Note: VIA! Touch Panels display composite video signals (not RF).
Use an RCA “Y” cable to split the video signal going to a VIA!; a
coaxial splitter or splitter/combiner will not pass composite video
signals!
