IF Interface and AUX Power
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.
(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.
Remote
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.
