Overview
2
 Features an underside switch for ID Bit control
1
 Has video bandwidth that exceeds 400MHz, making it suitable for the
highest resolution graphics signal distribution as well as for HDTV signal
distribution
 Accepts one input, provides necessary buffering and isolation, and
distributes the signal to 8 identical outputs
 Is 12VDC fed and is housed in a half 19" enclosure
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-8 away from
moisture, excessive sunlight and dust
1 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

2 Both the H sync switch and the V sync switch MUST be set identically (no harm will occur to the graphics source if the
switches are set to the wrong direction)
3 “Transistor-Transistor Logic” is a term used in digital electronics describing the ability of a device or circuit to be connected
directly to the input or output of digital equipment. Such compatibility eliminates the need for interfacing circuitry

5 Using Your VP-8 1:8 VGA/UXGA Distributor
You can use the VP-8 to output the VGA/UXGA signal from a laptop or a PC.
To output the XGA signal from a laptop’s graphics card to up to 7 monitors and a
projector, using a VP-8 (as the example in Figure 3 illustrates), do the following:
1. Connect an XGA source (for example, a laptop’s graphics card) to the
INPUT HD15F connector.
2. Connect the OUTPUT HD15F connectors to up to
1
8 acceptors. For
example, connect the OUTPUT connectors 1 to 7 to Monitors 1 to 7, and
connect the OUTPUT 8 connector to a Projector.
3. On the underside of the VP-8:
 Set both the H sync switch and the V sync switch to Hi-Z (TTL)
 Slide the ID Bit switch to the left to set to ON
4. Connect the 12V DC power adapter to the power socket and connect the
adapter to the mains electricity (not illustrated in Figure 3).
