•Use only good quality connection cables to avoid interference, deterioration

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-2L away from moisture, excessive sunlight and

dust

•Resolution of up to UXGA, ensuring that it remains transparent even in the

most critical applications

•Trimmers for output level and cable equalization

•An ID Bit control switch

•A LED power indicator

•A small enclosure housing

4 Connecting the VP-2L

Always switch off the power to each device before connecting it to your

VP-2L. After connecting your VP-2L, connect its power and then

switch on the power to each device.

To connect your VP-2L UXGA Line Amplifier, as the example in Figure 2 illustrates,

do the following:

1. Connect a computer graphics source to the INPUT 15-pin HD connector.

2. Connect the OUTPUT 15-pin HD connector to an acceptor (for example, a

display).

3. Connect the 5V DC power adapter to the 5V DC socket and connect the

transformer to the mains electricity or use the included USB cable to power

the unit as described below.

4. If required, adjust the video output signal level and/or cable compensation

equalization level.

Use a screwdriver to rotate the trimmers to adjust the appropriate level.

The VP-2L is supplied with the USB cable that:

•Has a USB-A connector at one end and a 5V DC jack at the other

•Connects to any USB port to power the unit

The internal Kramer P/N for this USB cable is 2518-0214003 C-UAM/DC35(THREAD)-3

To connect the VP-2L UXGA Line Amplifier using this cable:

1. Connect the 5V DC jack of the cable to the 5V DC socket of the VP-2L

(instead of using the 5V DC power adapter) and connect the USB-A

connector of the cable to the USB port of the display or computer.

The VP-2L receives power from the display or computer without needing a

power supply.
