3.2. Switch off of the Input-Impedance on the RGB-Inputs
With the switch A1 and A3 you can switch off the input-impedance of 750 Ω on the RGB-
video-input. You need this function if you use more than one monitor on the video-source.
Connecting several monitors to one single video signal, it is necessary to switch on the input
impedance at the last monitor in the row. ( all others are switched off)

3.3. Monochrom Presentation
To switch of the signals R and B please use the switch A2. Only the green video-signal will
be presented. The presentation of the picture is performed only in green.

3.4. Input-Impedance Sync-Signals
It is possible to switch the input impedance of the Sync-Signals H-Sync and V-Sync between
10 kΩ and 75Ω with switch A4. Standard-adjustment 10 Ω.

3.5. Editing of Synchronization-Signals
Switch A5 is activating a function, which edits the synchronization-signals of „Sync On
Green". If you activate this function the input for horizontal and vertical sync-signals will be
switched off. The synchronization is performed through the green video-signal.
This function has to be activated if monitors with older controls- and visualization systems like
AS320, CP526, WF470, Teleperm-M, are in use. This function eliminates different bugs on
the synchronization-signals and passes on the prepared synchronization-signal to the visual
display unit. This editing function is for horizontal frequency 15 to 35 KHz.
