NewsCaster VT2
4.5 CONTROL UNIT ELECTRICAL
INSTALLATION
Input Power
AC Power: The NewsCaster VT2 is standard
configured to operate on AC power ranging
from 90 to 260 VAC at 40 to 60 Hz. Connect
the provided AC line cord to an appropriate
AC power source. (Refer to Figure 6,
Detail 1.) Alternate line cord connector types
are available from Nucomm if needed.
DC Power: When configured for DC, the
system can operate on DC power ranging from
+11 to +32 VDC. Connect the provided DC
line cord between the lugs on the back of the
unit to an appropriate DC power source. (–)
for GND, and (+) for the +11 to +32VDC.
In all configurations, the system automatically
adapts to the input voltage without requiring
the user to change any jumpers, switches or
settings.
Video
All video inputs/outputs are made via clearly
marked 75 Ω BNC connectors. (Refer to
Figure 6, Detail 3 and Detail 4.) Simply
connect a 75 Ω coaxial cable between the
source and target equipment, and select the
appropriate input type via the front panel
interface. (Refer to Section 5 for details.)
Available video inputs and outputs are:
• SDI (Input) – (Serial Digital
Interface) This signal combines both
digital audio and digital video into one
signal.
• ASI IN – (Asynchronous Serial
Interface) Similar to SDI, this signal
combines both digital audio and digital
video into one signal.
M17-0002-01A Rev 0.0
• ASI OUT – (from the internal
encoder) The Output ASI connector
provides an output of the encoded
MPEG stream, and can be used to feed
a satellite modulator or external
transport stream multiplexer.
• Video (Input) – It is an analog video
signal that is proportional to the
received signal deviation. For use with
Composite and Baseband Video.
70 MHz input and output ports (75Ω BNC)
are provided.
The 70 MHz input port allows an externally
modulated signal to be inputted to the system
for RF transmission. To utilize this feature,
"External 70 MHz" must be selected as an
input via the front panel interface. Refer to
Section 5 for details.
The 70 MHz output port can be connected to a
spectrum analyzer for monitoring, or to an
external transmitter. (Refer to Figure 6,
Detail 2).
Note: When "External 70 MHz" input is
selected, the 70 MHz out is a loop-through
only.
