or 640X480, and 31.5 kHz RGBS Video. With the optional VIM-300,
15.75 kHz RGBS Video is recognized composite video and S-Video
will be processed and displayed.
The Loop-thru video output uses a standard 15-pin VGA type
connector for output to an external computer monitor or another
display. The format of the Loop-thru video is same as the source
video. VGA and MAC will have RGB with separate H-Sync and
V-Sync. RGBS video will come out RGBS with the composite sync on
the connector’s H-Sync pin. RGB Sync on Green sources will loop-
thru RGBS-Sync on Green. Displays with the VIM-300 option using a
Composite Video or S-Video source will not output a loop-thru signal
for those two sources.
The video cables used should be high quality and shielded to insure
the best image quality when displayed.
Using poor quality cables can lead to picture noise, jitter and
crosstalk.
Control data enters the display via the RS-232 In connection, and is
supplied to an adjacent display (if used) via the RS-232 Out
connector. High quality shielded cables designed for RS-232
communication should be used to ensure proper data transmission
and control.
