Runco VX-4c - Manual (Page 83)

1. 12v Fuse
This fuse protects the 12v outputs from the MASK and SCREEN jacks.
(Screen Fuse: 5mm x 25mm, AGC, 0.5A 250V Fast Acting, 250V, Fast Blow)
2. Mask
This is a 12V output that is used to trigger masking on screens that have that capability.
(For use on motorized screens only).
3. Screen
This is a 12V output that is used to trigger the screen to drop.
(For use on motorized screens only).
4. RS-232 In
This is for systems using serial (RS-232) to control the VHD Ultra Controller.
5. Reserved for future use.
6. RGB OUTPUT
This is the main output of the VHD Ultra Controller. The RGB Signal goes directly to the VX-4c/VX-6c
Projector. If component is used through the pass-through, then only the R (Pr), G(Y) and B(Pb) jacks will be
active. Individually, the jacks are: V=vertical sync, H=horizontal sync, B=Blue, G=Green, R=Red.
7. Pass-through
Anything input to this port will by-pass the processing of the VHD Ultra Controller and be sent straight to the
VX-4c/VX-6c Projector. This is useful for computer graphics and HDTV signals which do not require process-
ing.
8. Component Input
This is the input for component video from sources such as DVD players.
Note: The component output from a DTV decoder or a progressive-scan DVD cannot be used with this port;
it must be input to the Pass-through port.
9. S-Video Input
This is the input for S-video from sources such as Satellite receivers, S-VHS VCR’s and DVD players.
