KRAMER: SIMPLE CREATIVE TECHNOLOGY

Your VP-450 1:4 High Resolution UXGA DA

The VP-450:

 Accepts one input, provides correct buffering and isolation, and then distributes

the signal to 4 identical outputs on high-density 15-pin HD connectors

 Has a video bandwidth exceeding 400MHz, ensuring that the machine

remains transparent even at high-resolution graphics modes such as

UXGA (1600x1200)

 Accepts analog or digital syncs

and provides ID Bit control

 Can output video signals that are DC or AC coupled for maximum

flexibility (selected via red, green and blue coupling buttons)

To achieve the best performance:

 Connect only good quality connection cables, thus avoiding 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 and position your Kramer VP-450 away

from moisture, excessive sunlight and dust

1 The polarity is determined via a pair of underside switches. Note that both the Hs (horizontal sync) switch and the Vs

(vertical sync) switch should be set identically

2 Via an underside switch. Sometimes notebook computers refuse to output a VGA signal to an external VGA monitor. By

setting the ID BIT to ON, the notebook will output to an external VGA monitor

# Feature Function

1 BLUE DC-AC Switch

2 GREEN DC-AC Switch

COUPLING

RED DC-AC Switch

Switch to DC to select DC coupling

, switch to AC to select AC

coupling (removing the DC offset of the input signal)

4 Hs (Horizontal Sync) Switch

5 Vs (Vertical Sync) Switch

Set both switches

to Hi-Z (TTL

) if the source is, for example, a

digital graphics card. Set both switches to 75(ANALOG) if the

source is analog based, for example, an RGBHV source with coaxial

cable for sync

6 ID Bit Switch Slide to the left to set to ON

; to the right to set to OFF

1 Achieving the best linearity and signal fidelity

2 Both the Hs and the Vs switches should be set identically – since graphics cards do not have mixed (TTL and ANALOG)

syncs. (No harm will occur to the graphics source if the switches are set to the wrong direction)

3 “Transistor-Transistor Logic” for syncs with digital logic levels

5 Connecting Your VP-450 1:4 High Resolution UXGA DA

To output a UXGA

signal from a computer graphics card to 4 monitors, as the

example in Figure 4 illustrates, do the following:

1. Connect a UXGA

source (for example, a computer graphics card) to the

INPUT HD15F connector.

2. Connect the OUTPUT HD15F connectors to up to 4 acceptors, as follows:

 Connect the OUTPUT 1 connector to an acceptor (for example,

Display 1)

 Connect the OUTPUT 2 connector to an acceptor (for example,

Display 2)

 Connect the OUTPUT 3 connector to an acceptor (for example,

Display 3)

 Connect the OUTPUT 4 connector to an acceptor (for example,

Display 4)

3. On the underside of the VP-450:

 Set both the Hs and Vs switches to Hi-Z (TTL)

 Slide the ID Bit switch to the left to set to ON

 Set the RED, BLUE and GREEN COUPLING switches either to DC

or AC, according to the output requirements

4. Connect the 12V DC power adapter to the power socket and connect the

adapter to the mains electricity.

1 Or any resolution, such as VGA, SVGA, XGA, and so on
