NewsCaster VT2 Features 2.
NewsCaster VT2 Features Front Panel Cable Transceiver Communication to RF Unit ASI OUT ASI IN Future Encoder Expansion 4 Analog Audio 2 AES /EBU Audio SDI Composite MPEG2 Encoder Multi- format Modulator , , (COFDM VSB QAM) 10.
NewsCaster VT2 Features 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”.
NewsCaster VT2 Features Preset Keys: Nucomm has designed six Preset Keys into the front panel of the Newscaster VT2. These keys are used to instantly recall previously programmed configuration parameters such as frequency, modulation format, analog or digital, video and audio input type, etc. To program a Preset Key, first set the Newscaster VT2 to the desired operating configuration. Then hold one of the six Preset Keys in until a confirmation message is displayed (roughly 10 seconds).
NewsCaster VT2 • Features • • • Optional Four Form C Relay contacts controlled from the Control Unit. The RF Head components are housed in a weatherproof enclosure that mounts on the antenna pan and tilt housing, replacing the conventional power amplifier. This setup combines precise tuning of the transmitter frequency with exceptional output power. The RF unit is equipped with type “N” connectors for the directional and optional omnidirectional antenna(s).

NewsCaster VT2 Installation 4. INSTALLATION 4.1 UNPACKING & INSPECTION Unpack the NewsCaster VT2 and visually inspect for possible damage to the LCD, connectors, and surface areas. If damage is found, a claim should be filed with the transportation carrier. Save the shipping container and packing material for reshipment, as needed. 4.2 PRE-INSTALLATION CHECKOUT Connect the NewsCaster VT2 IF output to the RF Head via an appropriate IF cable (refer to Table 7.
NewsCaster VT2 Installation 6 NOTE: For detailed views of connectors and pin-outs, refer to Figures 10 thru 14. Depending on the configuration ordered, some units may not feature all of the connectors pictured here. 3 2 CAUTION – IF INTERFACE (7) The IF Interface center conductor carries +48V to power the RF Head.

NewsCaster VT2 4.5 Installation CONTROL UNIT ELECTRICAL INSTALLATION 70 MHz Connectors 70 MHz input and output ports (75Ω BNC) are provided. 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.
NewsCaster VT2 Installation 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. 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.
NewsCaster VT2 Installation Pan/Tilt Pwr PAN / TILT This optional connector is used to provide power to the Pan & Tilt Motor. See Figure 6, Detail 10 for connector location on the Control Unit. Detailed cabling info for 120VAC Pan & Tilt systems can be found in Table 10 and Figure 15. Detailed cabling info for 12VDC Pan & Tilt systems is found in Table 11 and Figure 16.
NewsCaster VT2 4.6 Installation mast atop an ENG/OB van. (See Figure 12 for a typical mounting setup.) RF HEAD MECHANICAL INSTALL Nucomm’s mast mounted transmitter consists of a single RF head (containing the upconverter, P&T, PSU, Antenna Controls, and amplifier). There is also a legacy “extended power output” option which consisted of two mast mounted units, the RF Head (containing the up-converter, P&T, PSU and Antenna Controls) and the High Power Amplifier (or HPA).
NewsCaster VT2 4.7 Installation PREPARING THE INTERCONNECT CABLES (INCLUDING NYCOIL) The NewsCaster VT2 is flexibly designed to use multiple IF cable types. The STANDARD cable types support diplexed +48VDC for transport to the RF Head. Belden 1694A (Coax) and Belden 8232A (Triax) are certified for this “one cable” configuration. Other common cables, such as Belden 1505, may require the use of the AUX Power option. Refer to Table 7 for more details on using the cables types mentioned.
