INSTALLATION AND SETUP
Video Loop Through !
To loop a single incoming video signal input (connected at the video decoder) through to anoth-
er projector or display device, use the empty connector(s) adjacent to this same input as described
below.
Composite Video Loop Through
CONNECTIONS: See Figure 2.15. From your source, connect a composite video signal to
INPUT 3 using either the small phono plug or the adjacent BNC. Connect a second cable from
whichever INPUT 3 connector is free to one of the composite video inputs of the next display
device or projector. Continue this looping method for each projector, using either the phono plug
or the adjacent BNC as input into INPUT 3, then using the other connector as an output (i.e.,
loop through). Whether you use the BNC or the phono plug as input or output depends on the type
of cable you have on hand and what type of connectors are on each end. If desired, connect one
audio signal to any projector as usual.
VIDEO TERMINATION: In the Preferences menu, make sure "Video Termination" is checked
for the final projector only. All other projectors must have this option unchecked in order for the
signal to continue. For other types of display devices in the chain, typically a "Hi-Z" switch posi-
tion is needed.
