Rear Panel Connectors
Connector Description
MAC
Macintosh II video signal input, 800x600 or 640x480 pixels.
15-pin D-Sub, female.
PC
IBM-compatible SVGA or VGA signal input, 800x600 or
640x480 pixels. 15-pin high-density D-Sub, female.
LOOP THRU
The selected video input is output from this 15-pin,
high-density, D-Sub, female connector (but see exception
below). The format of the loop-thru video is same as the
source video. PC and MAC will have RGB with separate H-
Sync and V-Sync. RGBS IN with separate composite sync
will come out the loop-thru as RGBS with the composite
sync on the connector’s H-Sync pin and separated V-Sync
on the V-Sync pin. RGB Sync on Green sources will loop-
thru as RGB-Sync on Green, plus composite sync on the H-
Sync output pin and separated V-Sync on the V-Sync pin.
Exception: If the selected input is Composite or S-Video, the
Loop-thru connector has no output. Composite and
S-Video have separate loop-thru connectors.
RGBS
(9-pin D-Sub,
male)
Video input from a 31.5 kHz device (such as scan-doubled
NTSC video). 9-pin D-Sub, male input. This input is
separate from the BNC RGBS input. Video can be cabled to
both the 9-pin D-Sub and the BNC connectors and selected
in the Source menu. With the VIM-300 option, this port will
also accept component 15.75 kHz video. Sync can be
composite sync on the S pin or sync-on-green.
This is also the input to use when coming from the Loop-
Thru connector of another display unit.
RGBS
(R, G, B, Csync;
4 BNC connectors)
Video input from a 31.5 kHz device (such as scan-doubled
NTSC video). BNC, female connectors. This input is
separate from the BNC RGBS input. Video can be cabled
to both the 9-pin D-Sub and the BNC connectors and
selected in the Source menu. With the VIM-300 option this
port will also accept component 15.75 kHz video. Sync can
be composite sync on the S connector or sync-on-green.
S-VIDEO
Only available with the VIM-300 option.
IN = NTSC, PAL or SECAM S-Video
OUT = buffered output of the input signal
