3 Overview The Kramer VA-10 Cable Delay Corrector is a cable delay (skew) corrector for RGB signals. The unit is designed to correct the problem of differing delay times in analog signals, such as RGB, or twisted pair signals that causes misconvergence on the display. The VA-10 lets you adjust and thus match the delays in the three signals. The VA-10 features controls for adjusting the red, green and blue skew (delay) individually and independently.

4 Connecting the VA-10 i Always switch off the power to each device before connecting it to your VA-10. After connecting your VA-10, connect its power and then switch on the power to each device. To connect the VA-10 (as the example in Figure 2 illustrates), do the following: 1. Connect a computer graphics source to the XGA INPUT of a PT-110 XGA Line Transmitter and connect the LINE OUTPUT on the PT-110 to the LINE IN RJ-45 connector on a TP-120 XGA Line Receiver unit.
