loops it out to a local monitor (or some other acceptor), as well as outputting
an amplified and equalized signal to a remote acceptor
Can drive very long high resolution lines1 due to its large bandwidth that
exceeds 480MHz. This ensures that it remains transparent even at highest
resolution QXGA modes
In particular, the VP-111 XGA Line Driver includes:
A TERM switch for input signal termination
Cable equalization control
ID Bit control (via a switch on its underside)
Achieving the best performance means:
Connecting 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)
Avoiding interference from neighboring electrical appliances that may
adversely influence signal quality and positioning your VP-111 unit in a
location free from moisture and away from excessive sunlight and dust

outputting the input signal from a laptop connected to an external VGA monitor4)
5 Connecting the VP-111 XGA Line Driver
To connect the VP-111, as the example in Figure 2 illustrates, do the following:
1. Connect an XGA source (for example, a laptop’s graphics card) to the
INPUT HD15F connector.
2. On the underside, slide the ID Bit switch to the right to set to ON.
3. Connect the OUTPUT HD15F connector to the acceptor (for example, a
projector).
4. Connect the LOOP HD15F connector to a local PC monitor and release
the TERM button to Hi-Z.
Note: if only a single output is required, leave the loop unconnected and
push in the TERM button to 75.
5. Connect the 12V DC power adapter to the power socket and connect the
adapter to the mains electricity.
6. Adjust5 the video EQ. (equalization) compensation, if required.
1 Insert a screwdriver into the hole and carefully rotate it, to trim the level
2 For looping select Hi-Z

4 Sometimes laptop computers refuse to output a VGA signal to an external VGA monitor if they do not detect the ID Bit as
ON. Set the ID Bit to ON using this switch so that the laptop will output to an external VGA monitor
