VP-771 – Overview 7
The VP-771
is housed in a 19” 1U rack mountable enclosure, with rack “ears”
included, and is fed from a 100-240 VAC universal switching power supply.
3.1 HDCP Compliance
If an HDMI signal is HDCP protected, it can only appear on HDMI
and DGKat outputs that are connected to HDCP compliant displays.
The VP-771 will not output an HDCP protected source to a display
that is not HDCP compliant. Instead it will show a black screen.
In the dual window display mode (see Section 7.2 ), even if only one
of the inputs is HDCP protected, and is output to a non-compliant
display, it will affect the entire screen and turn it black.
3.2 About the Power
Connect™ Feature
The VP-771 can power the receiver on the DGKat output when the devices are
within 90m (270ft) of each other. The Power Connect™ feature applies as long as
the cable can carry power and the distance does not exceed 90m on standard TP
cable. For longer distances, heavy gauge cable should be used (TP cable is still
suitable for the video/audio transmission, but not for feeding the power at these
distances).
3.3 Using Twisted Pair Cable
Kramer engineers have developed special twisted pair cables to best match our
digital twisted pair products; the Kramer: BC-DGKat524 (CAT 5 24 AWG), the
Kramer: BC-DGKat623 (CAT 6 23 AWG cable), and the Kramer: BC-DGKat7a23
(CAT 7a 23 AWG cable). These specially built cables significantly outperform
regular CAT 5 / CAT 6 / CAT 7a cables.
