2.3 Shielded Twisted Pair
Kramer engineers have developed special shielded 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), and the Kramer
BC-DGKat7a23 (CAT 7a 23 AWG) cables. These specially built cables
significantly outperform regular CAT 5/CAT 6 /CAT 7a cables.
The VM-1H4C supports a range of up to:

Up to 90m (295ft) at 1080i, or up to 30m (98ft) at 1080p on shielded
BC-DGKat524 cable

Up to 90m (295ft) at 1080i, or up to 70m (230ft) at 1080p on shielded
BC-DGKat623 cable

Up to 100m (330ft) at 1080i or up to 90m (295ft) at 1080p on shielded
BC-DGKat7a23 cable
You can daisy-chain up to six DigiKat devices with the maximum overall distance
between the first and last devices being cumulative and limited to 500m.
2.4 About the Power Provision Feature
Only the VM-1H4C needs to be connected to a power source when the devices
are within 90m (270ft) of each other – the VM-1H4C can provide power to the
receiver over the TP cable. This feature applies as long as the cable can carry
power and the distance does not exceed 90m on standard TP cable. For longer
distances, heavier gauge cable should be used (standard TP cable is still suitable
for the video/audio transmission, but not for feeding the power at these distances).
