User Manual 

 

 
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. 
 

 
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) 
•  ASI IN  
•  ASI OUT (from the internal encoder) 
•  Video (Input) – For use with 

Composite and Baseband Video. 

 
 
 

 
70 MHz input and output ports (75

Ω 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 70MHz” 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. (see Figure 6, Detail 2). 
 
Note: When “External 70 MHz” input is 
selected, the 70 MHz out is a loopthrough 
only. 

Figure 7: Control Unit, Audio Connector 

 

 
The Analog and Digital audio inputs are made 
via a strip terminal on the rear panel.  (Refer 
to Figure 6, Detail 6 for connector location.)  
The terminal marked "G" is for the ground 
lead, (-) is for the negative signal and (+) is 
for the positive.  (Refer to Figure 7 for the 
connector detail.)
