Quick Start — CrossPoint 450 Plus
and MAV Plus Switchers
Installation
Step 1
Turn off power to the input and output devices,
and remove the power cords from them.
Step 2 (video models)
CrossPoint 450 Plus
— Cable the switcher for
RGBHV, RGBS, RGsB, RsGsBs, component/
HDTV video, S-video, or composite video input
and output.
MAV Plus video models
— Cable the switcher
for component/HDTV video, S-video, or
composite video input and output.
See chapter 2, Installation, to connect the
various video formats to and from the
various models.
Step 3 (audio models)
Most audio models
— Cable the switcher for
audio input and output. High impedance is
generally over 800 ohms.
MAV Plus 128 AV RCA
— Cable the
switcher for stereo audio input and
output. Each input and output has two
RCA connectors (left and right) for
unbalanced audio input or output.
Step 4
If desired, connect a control
system or computer to the
Remote RS-232/RS-422 port.

a control system, or computer to the Ethernet
RJ-45 port. See chapter 2, Installation, for details.
• Network connection — Wire as a patch
(straight) cable.
• Computer or control system connection —
Wire the interface cable as a crossover cable.
Step 6 (MAV Plus)
If desired, attach
an external sync
timing device to
the external sync
connectors.
Step 7
Plug the switcher
into a grounded AC
source.
