INSTALLATION

5.
D15F connector output for use with computer
monitors or to a second display device. Use
only short cable runs. This output can be used
at the same time as the BNC outputs
6.
BNC connectors for main output with RGBHV
or YPrPb signals to display devices. Cable
runs up to 100ft are okay if good quality cables
are used. For YPrPb outputs use:
Red =
Pr
Green =
Y
Blue =
Pb
RGBHV is recommended.
Note: If Computer signals are to be used, separate H
& V sync cables must be connected to the display.
7.
12V trigger to activate automatic screen relays.
Voltage is constant when unit power is on.
(12V, 3.5mm, 2 pin, Tip=+ )
8.
IR receiver connection allows for use with
external IR receivers so unit can be installed
behind walls. (5V-12V, 3.5mm, Tip=+)
9.
RS232 D9F connection for use with RS232
control systems
10.
AC Power connection.
11.
DVI Input . DVI input is for pass-though to the
DVI output only. DVI to RGB output is not
available
12.
DVI Output: Digital interface for compatible
displays. All analog and digital inputs are
output through this connection. Maximum
cable length is 50ft. For longer lengths a
distribution system or fiber optic system must
be used.
Note: The DVI or analog RGBHV outputs cannot be
active at the same time. Select the output type in the
Setup menu prior to use of the processor.
Connecting HDTV Satellite Receivers
Since HDTV ready satellite receivers offer different
signal types, they require special attention for
connection to the processor. Every receiver is
different so be sure to consult the receivers manual
for details. For this manual, we will assume the
receiver being used operates as follows:
1. Non HDTV material is output from the receiver
via an S-video connection
2. HDTV material is output via YPrPb outputs
3. If available, HDTV material is also output via a
DVI connector.
The following diagram offers one way to connect
the system.
Note: The NRS-DVI pass-through input will “pass ”
the input signal to the output stage in the same
format as the input signal, i.e. analog HDTV in –
analog HDTV out, DVI HDTV in – DVI HDTV out.
The HDTV signal cannot be converted from analog to
digital or digital to analog. Also, HDTV signals with
HDCP encription will not pass through the NRS-DVI.
Simply switch to the analog YPrPb output of the
satellite receiver and switch the NRS-DVI output to
analog RGBHV to view the signal.
As an alternative input, the NRS-DVI will auto-detect
the HDTV signal (1080i & 720p) on the YPrPb inputs
(BNC) and switch the signal to the pass-through
output. Any 480p or 480i signal will be sent to the
processing stage to be scaled to the output
resolution.
With this hookup viewing the different sources is as follows:
