3 Overview
The VS-41DVI-R is a technologically advanced, high quality 4x1 Switcher
for DVI-D signals supporting the DDWG DVI 1.0 standard.
With a bandwidth of 1.65GHz, the VS-41DVI-R can switch signals having
resolutions up to UXGA, including all HDTV formats. Since high-resolution
DVI signals are very sensitive to cable quality and to PCB layout, the
VS-41DVI-R uses a carefully designed PCB, which includes all buffering,
conditioning and amplifying circuitry to provide a re-clocked
top-notch output signal.
In addition the VS-41DVI-R:
 Includes a built-in reclocking block that re-generates the DVI signal, so
that several units may be cascaded
 Can read and store, in non-volatile memory, the EDID
1
block of the
display device. It can then provide the EDID information to all of the DVI
sources even if the display device is not connected
 Does not support HDCP (High Definition Digital Content Protection)
 Has five DVI-I connectors to make it compatible with all types of DVI
cables
 Fits in one vertical space of a standard 19” professional rack enclosure
Achieving the best performance means:
 Connecting only good quality connection cables, thus avoiding
interference, deterioration in signal quality due to poor matching, and
elevated noise levels (often associated with low quality cables)
 Avoiding interference from neighboring electrical appliances and positioning
your VS-41DVI-R away from moisture, excessive sunlight and dust

Table 2 define the front and rear panels of the VS-41DVI-R, respectively.
