6.4 Setup at the Remote Unit
After unscrewing and opening the upper shell, please place the device with the CATx-
connectors to the right and the monitor connector to the left.
The main PCB then will look like this:

Selecting the moment of switching to the next frame
The transmission of screen data is not synchronous to the screen change of the graphic card.
Normally, the transmission is terminated when a frame is displayed on the screen. If the
device switches to the new frame during HSYNC, the displaying period of the old frame, you
may see horizontal screen breaks at the moment of switching (default). Alternatively, you can
set up the units to idle until the actual frame is displayed completely, during VSYNC. Using
this method, the number of frames per second transmitted is lower.
Moment to switch
JP3 Behaviour
Switching during HSYNC
(default) Higher frame rate but (possibly) horizontal breaks
detectable
Switching during VSYNC
Lower frame rate, no horizontal breaks detectable
but (possibly) stepping pictures
