in signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
•Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
•Position your Kramer VP-473 away from moisture, excessive sunlight and
dust

4 Connecting the VP-473
Always switch off the power to each device before connecting it to your
VP-473. After connecting your VP-473, connect its power and then
switch on the power to each device.
To connect the VP-473, as illustrated in the example in Figure 2:
1. Connect the SDI video source (for example, a digital camera) to the SDI IN
BNC connector.
2. Connect the SDI OUT BNC connector to the SDI display.
3. Connect the LEFT and RIGHT AUDIO OUT RCA connectors to the
unbalanced stereo audio amplifier.
4. Connect the PC/HD OUT connector to the graphics acceptor (for example, a
plasma display). If using a 15-pin HD to component cable, connect the pins
as shown in the following table.
You can use a breakout cable, such as the Kramer C-GM/3RVF. If you have a VGA to a
5BNC cable, use the RGB connections only.
Pin Number Signal
