# Feature Function
1 BLUE DC-AC Switch
2 GREEN DC-AC Switch

COUPLING
RED DC-AC Switch
Switch to DC to select DC coupling
1
, switch to AC to select AC
coupling (removing the DC offset of the input signal)
4 Hs (Horizontal Sync) Switch
5 Vs (Vertical Sync) Switch
Set both switches
2
to Hi-Z (TTL
3
) if the source is, for example, a
digital graphics card. Set both switches to 75 (ANALOG) if the
source is analog based, for example, an RGBHV source with coaxial
cable for sync
6 ID Bit Switch Slide to the left to set to ON

; to the right to set to OFF
1 Achieving the best linearity and signal fidelity
2 Both the Hs and the Vs switches should be set identically since graphics cards do not have mixed (TTL and ANALOG)
syncs. (No harm will occur to the graphics source if the switches are set to the wrong direction)
3 “Transistor-Transistor Logic” for syncs with digital logic levels
4 Enabling the notebook or laptop to output a VGA signal to an external VGA monitor
