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
Go to http://www.kramerelectronics.com/support/product_downloads.asp
to check for up-to-date user manuals, application programs, and to check
if firmware upgrades are available (where appropriate).
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 VP-472 away from moisture, excessive sunlight and
dust
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.

Always switch off the power to each device before connecting it to your
VP-472. After connecting your VP-472, connect its power and then
switch on the power to each device.
To connect the VP-472 as illustrated in the example in Figure 2:
1. Connect the SDI source (for example, an SDI camera) to the SDI IN BNC
connector.
2. If required, connect the SDI LOOP BNC connector to the SDI acceptor (for
example, an SDI display).
3. Connect the HDMI OUT connector to the HDMI acceptor (for example, a
plasma display).
The VP-472 outputs on both the SDI OUT and HDMI connectors simultaneously
4. Connect the 5V DC power adapter to the power socket and to the mains
electricity (not shown in Figure 2).
