Installation (cont’d)
Pre-Wire
The VIA!4.0 requires power, control, status, and video 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 central 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 PVIA1, PVIA4,
PVIA10, or PS12 Precision Panel (typically at the head-end).
Maximum wire run is 220 feet.
Video
The VIA!4.0 has 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. The VIA!4.0 has F-connectors on
both Input and Loop Output.
Note: The VIA!4.0 displays 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!
