Loop-Thru Of Source Video - Clarity Tigress S WN-5230A-S User Manual

If there are other video sources on different input connectors that will
use Big Picture, go through the previous process for each video
source. Then save these settings.

Loop-Thru of Source Video

Loop-thru works in different ways depending on the type of source.
If the source video is PC or MAC
LOOP-THRU connector, which can be connected to the next unit's PC
input.
If the source is RGB with separate composite sync
(progressive scan), it will come out the LOOP-THRU connector as
RGB with the composite sync on the connector's H-Sync pin and
separated V-Sync on the V-Sync pin. Feed this to the next unit's RGBS
connector. It might also work to feed this to the next unit's PC
connector.
If the source is RGB Sync on Green
come out the LOOP-THRU connector as RGB-Sync on Green, plus
composite sync on the H-Sync output pin, and separated V-Sync on
the V-Sync pin. Feed this to the next unit's RGBS connector. It might
also work to feed this to the next unit's PC connector.
If the source is RGBS at 15.75 kHz (interlaced), the output from the
LOOP-THRU connector will also be 15.75 kHz. It will not work to loop
this output to the next display's PC input, because the PC input is
expecting 31.5 kHz. To loop RGBS at 15.75 to the next display, make
an adapter to go from 15-pin to 9-pin using the wiring diagram below.
Standard 15-pin-to-9-pin adapters may also be available from some
computer stores. Connect the first display's LOOP-THRU output to the
next display's 9-pin RGBS input. Alternatively, use a 15-pin to 4-BNC
adapter cable. These are also usually available from electronics or
computer stores.
Composite and S-video inputs have their own separate loop-thru
connectors. These are buffered. The inputs are terminated in 75 ohms.
Using video loop-thru slightly degrades signal quality as the signal
goes through each cube. The amount of degradation depends on
cable quality, source video, and the number of loops. If this
degradation becomes a problem, use a signal splitter or distribution
amplifier to directly drive each cube or to at least reduce the number of
loops.
