NewsCaster VT2 Features
M17-0002-01A Rev 0.0 15 User Manual
In Analog mode, the NewsCaster VT2 accepts
SDI or Composite video, and LINE,
Embedded, or AES audio.
The NewsCaster VT2 can also accept
externally modulated signals via the 70 MHz
Input Port.
Audio Sub-carriers:
The two standard (or four optional)
synthesized audio sub-carriers are field
programmable and feature individual source
selection (OFF / LINE / TONE / AES) and
gain control via the menu system or audio
“Quick-Key”. The sub-carrier frequencies,
mode, and additional gain are front panel
adjustable using the menu system.
Prime Power:
The standard Control Unit input voltage is 90
to 240 volts AC (40 to 60 Hz). Optionally, the
system can be configured for DC ranging from
+11 to +32 VDC, or for both AC & DC
operation in the ranges listed above. In all
configurations, the system automatically
adapts to the input voltage without requiring
the user to change any jumpers, switches or
settings. Appropriate line cords are provided.
Standby Mode:
The Standby Mode is accessed from the front
panel under the grouping labeled “MODE”.
There are several options or functions that can
be selected.
Normal Mode: In the “NORMAL” mode,
the NewsCaster VT2 amplifiers are powered
and transmitting.
Standby Mode: In the “STANDBY” mode,
the transmitter is powered on, but the RF
output is muted, enabling the transmitter to be
tuned safely without radiating off-frequency
emissions. The NewsCaster VT2 will remain
in “STANDBY” until on-frequency lock has
been obtained. Switching from “STANDBY”
to the “NORMAL” (operating) mode results
in instantaneous on-frequency transmission.
If the synthesizer has not attained lock when
Standby Mode is switched to “NORMAL”,
the unit will remain in STANDBY” until on-
frequency lock has been obtained.
V Present Standby:
When the transmitter is in the Analog mode
there is an additional “STANDBY” mode
called “V.Pres. Sdtby” (Video Presence
Remote). When in this mode, the transmitter
will be in the “Normal” transmitting mode as
long as the video source is connected to the
Video or SDI input. When the video is
removed, the transmitter will go to
“STANDBY” within five seconds.
Reapplying the video will immediately turn
the transmitter back ON. The Video Presence
Remote Standby mode enables the camera
operator to remotely place the transmitter in
standby or turn it ON.
Dynamic Color Bar Generator:
To activate the Dynamic Color Bar Generator,
press the “TEST COL” button on the front
panel of the Control Unit. The LED above the
button will light. The color bar pattern is the
SMPTE color bar standard.
In the middle of the pattern is a 16 character
ID that can be programmed through the LCD
display. The first character in the ID will
blink to indicate that the microwave link is
active. (In a digital system if the decoder
stops decoding, the picture will freeze and the
operator would have no way of knowing this
without the blinking character title.)
In addition to numbers and characters, several
symbols are available for display in the ID.
These symbols include a helicopter, a Van, a
camera, etc.
