Connecting a S-Video (or Composite Video)
source to Port 2
Separate Y-luma/C-chroma signals for higher quality playback of
Super VHS signals can be connected to Port 2 . A composite video
signal can also be connected to this port.
To select the S-video input :
Press the
digit button 2
on the RCU or the local keypad
.
In case of using Port 2 for connecting the Composite Video, the
selection of this source have to be done inside the "Picture Tuning"

W
Termination Switch for S-video
Terminate the S-video input of the projector using the 75
Ω
switch next
to the S-video input when the projector operates alone or when the
projector is the last unit in a loop-through configuration.
The switch is set to "ON" : signal terminated.
The switch is set to "OFF": signal not terminated.
Connecting a RGB Analog source to Port 3
Connect a RGB Analog signal via an interface (e.g. RGB 120MHz
interface, part number 98 26570) to Port 3. RGB analog input with
automatic sync detection (Separate H and V sync inputs, with
composite sync input or with sync signals on green) and automatic
polarity detection.

termination resistors must be removed from the RGB Input Auto Sync
Tracking Module when the projector is NOT the last unit in the chain.
In case of a stand-alone projector, do not remove the resistors.
