Appendix C. Receiver Video Modes
The Cat5 Multi VGA System receivers feature the ability to display five component
RGBHV computer video as well as RGBS, RGsB and full component RGB video.
The transmitter units need no configuration changes.
The AC1001A-R2 has an external switch (SW3) that controls whether RGBHV or
non-RGBHV signals are in use. Please see silkscreen on the top cover of the unit
for the SW3 position to use.
The AC1002A-R3, AC1013A-R2, AC1014A-R2 feature an auto-sense mode to
determine RGBHV or not is in use. This mode can be overridden if necessary as
shown below:
AUTO SYNC MODES:
JP8 controls sync clamping circuitry and works with the
external switch labeled AUTO CLAMP.
The default sync mode is AUTO CLAMP OFF which will
autosense between RGBHV and non-RGBHV signals.
Turning the External AUTO CLAMP switch ON will set the
sync clamp mode to RGBHV video modes
If non-RGBHV video is desired with AUTO CLAMP ON,
jumper JP8 must be set to IN.
JP13 controls sync clamping circuitry and has 3
settings depending on the video signal in use:
RGBHV computer video with separate
horizontal and vertical sync:
Jumper JP13 to positions 1-2
Non RGBHV video, component RGB/YUV, S-
video, composite video or RGsB video:
Jumper JP13 to positions 2-3
Auto sense video mode:
JP13 non-jumpered.
