3.1 Summarizing the HDMI Line Transmitter/Receiver System
Using the PT-571 HDMI Line Transmitter with the PT-572+ HDMI Line
Receiver constitutes an HDMI-to-twisted pair transmitter and receiver
system, when used with an STP (shielded twisted pair) cable. The HDMI
Line Transmitter/Receiver system features:
•Maximum data rate/bandwidth up to 1.65Gbps
•HDTV compatibility and HDCP compliance
•HDMI Support – HDMI (V.1.4 with Deep Color, x.v.Color™, Lip
Sync, HDMI Uncompressed Audio Channels, Dolby TrueHD, and
DTS-HD)
•EDID PassThru that passes EDID/HDCP signals from source to
display
•3D pass-through
•System Range1
•Power Connect™ that feeds 12V DC over the CAT 5 cable from
transmitter to receiver (see section
- Up to 90m (295ft) at 1080i, or up to 30m (98ft) at 1080p
on shielded BC-DGKat524 cable; 90m (295ft) at 1080i, or up to 70m
(230ft) at 1080p on shielded BC-DGKat623 cable; 100m (330ft) at
1080i or up to 90m (295ft) at 1080p on shielded BC-DGKat7a23 cable

3.2 About the Power Connect™ Feature
The Power Connect™ feature here means that only one unit in a system, the
transmitter or receiver, can be connected to a power source when the
devices are within 270 feet (90 meters) of each other. The Power Connect™
feature applies as long as the cable can carry power. The distance does not
exceed 90 meters on standard CAT 5 cable, for longer distances, heavy
gauge cable should be used2
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.
1 Note that the transmission range depends on the signal resolution, graphics card and display used The distance using non-
Kramer CAT 5, CAT 6 and CAT 7a cables may not reach these ranges
2 CAT 5 cable is still suitable for the video/audio transmission, but not for feeding the power at these distances
