User Manual 

The Digital AES/EBU inputs are made via the 
Audio 1 & Audio 3 terminals.  As such, only 
one Digital audio is available in the standard 
“two audio” configuration. 
 

 
When the IF Cable is suitable, a single TNC 
(or optional Triax) connector (Figure 6, Detail 
7) is used to output the three signals that must 
pass between the Control Unit and the RF 
Head: 
 

(a) the modulated 70 MHz signal 
(b) the inter-unit control data 
(c) the +48VDC for the RF Head. 

 
For cases when an existing non-conforming IF 
cable that cannot handle +48VDC must be 
used, the AUX Power option must be fitted 
and will provide the +48V on a separate 
connector (Figure 6, Detail 5) for transport to 
the RF Head via dedicated conductors. 
 
Table 7 lists conforming cables and details the 
various configurations possible with and 
without the AUX Power option. 
 
NOTE:  When AUX Power is configured, the 
+48v still remains available at the IF 
Interface port.  This allows the user to 
upgrade to a conforming IF cable without 
requiring any changes to the unit. 
  
Additional detailed information on the 
interconnection between the Control Unit and 
RF Head is found in Sections 4.7 through 4.9. 

 
The remote control port (Figure 6, Detail 8) 
allows for full control and monitoring of the 
NewsCaster VT2.  Both RS232 and RS485 are 
supported.  Refer to Section 5.3.2 for settings.  
Refer to Figure 8 for pin-out.

This optional 6-pin connector (Figure 6,
