2 Getting Started
We recommend that you:
Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
Review the contents of this user manual
2.1 Achieving the Best Performance
To achieve the best performance:
Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
Do not secure the cables in tight bundles or roll the slack into tight coils
Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
Position your Kramer VM-1H4C away from moisture, excessive sunlight and
dust

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).
