Introduction
The NTVPIPSW is a KVM multi-view switcher which allows switching between four HDMI sources together
with USB signals and audio signals and also supports touch screen. There is a line in/microphone input, which
could be mixed with source audio and there is an analogue audio output as well. As a USB2.0 switcher, it sup-
ports 2 standard USB devices shared by 4 computers. The NTVPIPSW can be controlled by keyboard hot keys
as well as the front panel buttons with LED indicators showing switching modes.
Using the multi-viewer function, operators working on several independent PCs benefit greatly from the abil-
ity to use a single keyboard and mouse kit to roam across and control all 4 computers, without having to se-
lect or press any button. It supports a cascade for 5 units, so one operator could control 16 computers at the
same time.
NTVPIPSW is the right choice for applications like the banking and financial sector, stock operation centres,
computer gaming, boardrooms and broadcasting, in command and control rooms and other mission-critical
applications where users need fast and accurate switching across multiple computers.
