DVI-D FIBER KVM-EXTENDER

4.2Setup at the Remote Unit

After unscrewing and opening the upper shell, please place the device in this orientation: with the Fiber connectors to the right and the electrical connectors to the left.

The main PCB then will look like this:

JP1, JP2, JP3

Use the diagram to locate jumpers.

Selecting the moment of switching to the next frame

The transmission of screen data in not synchronous to the screen change of the graphic card. Normally, the transmission is terminated during displaying a frame on the screen. If the device switches to the new frame during the displaying period of the old frame (somewhere on the screen), it’s possible, that you can see horizontal screen breaks in the moment of switching. On the other hand the device must idle, until the actual frame is displayed completely (until VSYNC) -> the number of frames per second transmitted sinks.
