Top Side Panel
Lower Side Panel
The VP-250:
Accepts one input, provides correct buffering and isolation, and then distributes
the signal to 2 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 syncs1 and provides ID Bit control2
Can output video signals that are DC or AC coupled for maximum
flexibility (selected via the 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-250 away
from moisture, excessive sunlight and dust

Figure 1, Figure 2 and Table 1 define the VP-250 unit:
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

COUPLING
Switch to DC to select DC coupling1, switch to AC to select AC
coupling (removing the DC offset of the input signal)
Set both switches2 to Hi-Z (TTL3) 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
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)

5 Connecting Your VP-250 1:2 High Resolution UXGA DA
To output a UXGA1 signal from a computer graphics card to two monitors, as
the example in Figure 4 illustrates, do the following:
1. Connect a UXGA1 source (for example, a computer graphics source) to the
INPUT HD15F connector.
2. Connect the OUTPUT HD15F connectors to up to 2 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)
3. On the underside of the VP-250:
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.
