NewsCaster VT2 M17-0002-00A Rev 4 10 User Manual
NewsCaster VT2 Description M17-0002-00A Rev 4 11 User Manual 1. DESCRIPTION Nucomm’s NewsCaster VT2 series is a two box Digital and Analog ENG/OB Microwave Transmitter System. The Mast Mounted Microwave Transmitter is designed to operate in any specified band in the 1.00 to 15.5 GHz frequency range. Each unit is field programmable and configurable to meet a wide range of customer requirements. The NewsCaster VT2 is a “split-box” transmitter system utilizing a rack-mounted Control Unit (19” x 1RU, sometimes referred to as the “IDU”), and a Mast Mounted transmitter RF Head (or “ODU”). The two are connected with a single IF cable (RG-6 coax, or optional Triax), which carries the 70 MHz IF, Control Data, and DC power. For cases where an existing IF cable in the Nycoil must be used, and cannot support the diplexing of the DC power, the NewsCaster VT2 can be fitted with an AUX Power output to send the power via separate conductors. (Refer to Table 8.) The NewsCaster VT2 is fully integrated with an Analog FM modulator, compliant super-low delay MPEG 2 Encoder and Multimode Digital Modulator. Available modulations include FM (NTSC / PAL), COFDM, optional single carrier QAM, and optional VSB. As additional digital modulation formats become available, the VT2 can easily be software updated. This makes the VT2 extremely flexible while greatly reducing circuit complexity. Figure 1: NewsCaster VT2 System Diagram Highlighted features include six “Quick-Key” presets that allow single button operation, integrated dynamic color bars, and HD transport capability. Also, special menus have been included to ease the BAS relocation process. Other available options for the NewsCaster VT2 include Pan & Tilt control, a 10Watt Digital High Power Amplifier, remote control and monitoring functionality, multi-band operation, etc. This manual is written in a general form to cover all configurations and options for the NewsCaster VT2 within the 1.00 to 15.5 GHz frequency range. The convention of this manual is to show non-standard configuration options with shaded text, as shown here.
NewsCaster VT2 Features M17-0002-00A Rev 4 12 User Manual
NewsCaster VT2 Features M17-0002-00A Rev 4 13 User Manual 2. FEATURES Figure 2: NewsCaster VT2, Simple Block Diagram Nucomm’s NewsCaster VT2 Series Digital-Analog ENG/OB microwave transmitter was designed with the 2GHz BAS Relocation in mind, and is optimized for ENG/OB truck applications. Nucomm has led the way in creating the most comprehensive ENG/OB transmitter available, with many state-of-the-art features not found in any of the other competing models. Control Unit Features: Fully integrated features of the Control Unit (as shown in Figure 3) include: • Smart LCD Display for system control • Six Quick-Key presets that allow single button configuration. • Integrated dynamic color bars. • Super low delay MPEG-2 using a 4:2:2 or 4:2:0 encoder. • Multi-Mode modulator that includes COFDM, Analog FM and optional VSB, DVB-S or QAM modulation • High data rate HD transport. • Special menus to ease the BAS relocation process. • Antenna polarization selection, CW, CCW, H, V. • Omni/Directional antenna selection (Optional). • Control of four Form C relay closures in the RF Head (Optional). • Integrated Pan / Tilt Control (Optional) • Joystick for Pan / Tilt (Optional) Digital & Analog Input Signals: The NEWSCASTER VT2 Control Unit accepts multiple input formats. These include: • Composite video (NTSC & PAL). • Digital video as SDI, with audio de-embedding. • ASI. • Two analog audio (optionally four). • One digital AES/EBU audio (optionally four). • 70 MHz. The audio’s can be combined with the video via the MPEG-2 encoder or the FM sub-carriers. A key feature of the Newscaster VT2 is that the SDI video can be converted internally to composite video and transmitted as FM analog modulation. The Audio and Video signal flow is shown in Figure 3. In Digital mode, the NewsCaster VT2 accepts video as SDI, ASI, or Composite, along with LINE, Embedded, or AES audio(s), and digitally compresses the signals using 4:2:2 or 4:2:0 MPEG2 encoding. The encoded signal is then internally modulated with one of the user-selected formats: COFDM, or optional QAM or VSB. (Refer to Figure 3). For additional flexibility, an ASI Out port is provided, enabling the NewsCaster VT2 to be used as a standalone ASI Encoder 4:2:2MPEG2EncoderModulatorAnalogFM Mod DVB-S orVSB or QAMControl Unit with Dynamic Color Bar/IDUp Converter andPower AmplifierRF OutputCoax CableSDI Video 4 x Audio2 switchableTo DigitalASI70 MHzNote: Optional Lower Cost 4:2:0 Encoder AvailableRF Head

NewsCaster VT2 Features M17-0002-00A Rev 4 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 three options or functions that can be selected: “Normal”, STANDBY” and V.PRES.STBY”. In the “NORMAL” mode, the NewsCaster VT2 amplifiers are powered and transmitting. 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 the Standby switch is switched to “NORMAL”, the unit will remain in STANDBY” until on-frequency lock has been obtained. 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” in 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 know way of knowing this. By causing one of the ID characters to blink, one can quickly tell that the link is operating properly. 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. When the Dynamic Color Bar Generator is activated, a 1 kHz test tone is inputted to the active audio channels. The left channel will be a CW tone. The right channel will be a pulsed tone.
NewsCaster VT2 Features M17-0002-00A Rev 4 16 User Manual 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). To recall the Preset, simply press appropriate key. The display will indicate the Newscaster VT2 has been re-configured per the Preset. Frequency Coverage: Nucomm’s NewsCaster VT2 transmitters are available in single-, dual-, and tri-band configurations. This manual covers all the models in the NewsCaster VT2 series. The NewsCaster VT2 series radios provide full coverage of the 2, 7 & 13GHz US frequency bands, and/or other bands as required internationally, from 1 to 15.5 GHz. The US frequency bands are given in Table 1 through Table 5. Band and channel selections are made and clearly displayed via the front panel LCD interface. Antenna Operation: The Newscaster VT2 can control a number of antenna functions, including: Polarization switching Directional-Omni antenna switching Selection between RWI or NSI Antennas Coax Cable Requirements: The NEWSCASTER VT2 Control Unit and RF Head are typically connected with a single Coax or Triax cable, which carries the 70MHz IF and the Control Data signals, and in a typical system, the power to the RF Head, which is diplexed onto the center conductor of the cable for coax, or through the inner shield when Triax is used. The cable conductor must carry 2 to 3 amps of current at +48 volts. .The center conductor of Belden 1694A/RG 6U coax (or equivalent), and the inner shield of the Belden 8232A/RG59U triax are large enough to carry this current with a minimum of voltage drop. When using video cable such as RG 58, or Belden 1505/RG-59U, the voltage drop through the center conductor is too great to carry the diplexed +48volts. To support the use of these cables which may be existing in the Nycoil and must be used, Nucomm has provided an auxiliary power (“AUX Power”) connector that routes the power to external wires. Refer to Section 4.7 for details. The standard coax cable required between the Control Unit and the RF Head must have an impedance of 75 Ohms. The Newscaster will on occasion, be used to replace systems that use 50 Ohm RF or video type coax cable in an existing Nycoil. On special request, Nucomm can configure the Newscaster VT2 system to operate using these 50 Ohm cables. Again, depending on the type of coax cable used in the pre-existing Nycoil, the power to the RF Head may require the use of the AUX Power option. RF Head Features: The rugged NewsCaster VT2 RF Head, as shown in Figure 4, includes: • IF to RF Up-Converter • RF Power Amplifier • Low Noise Frequency Synthesizer • Diplexer that splits the +48 volts, the 70 MHz and the Control Data. • DC to DC Converter • Optional Pan & Tilt Controller • Optional Omni/Directional Antenna switch.
NewsCaster VT2 Features M17-0002-00A Rev 4 17 User Manual • 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 omni-directional antenna(s). Other Standard Features: • Digitally synthesized microwave oscillator tuning. • RS232/RS485 Remote. • RF Power Output Adjustments. • Field Programmable RF and ASC settings. Other Options: • Remote Control Software allowing the NewsCaster VT2 to be fully monitored and controlled from an IBM Compatible PC through a RS232C/RS485 port. • High Power Amplifier (20 Watt Analog, 10 Watt Digital). • Mounting Adapter Plates enabling mounting of the RF Head and High Power Amplifier to the Pan and Tilt.

NewsCaster VT2 Installation M17-0002-00A Rev 4 31 User Manual 4.5 CONTROL UNIT ELECTRICAL INSTALLATION 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. 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. Video 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 Connectors 70 MHz input and output ports (75Ω 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 Audio 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.) Pin # Function G Ground + Positive - Negative
NewsCaster VT2 Installation M17-0002-00A Rev 4 32 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. 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. 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.

NewsCaster VT2 Installation M17-0002-00A Rev 4 34 User Manual 4.6 RF HEAD MECHANICAL INSTALL Nucomm’s mast mounted transmitter consists of a single RF head (containing the up-converter, 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). The legacy system is no longer manufactured. In a typical installation of Nucomm's NewsCaster VT2, the RF Head (and HPA if configured) are mounted on the Pan & Tilt mechanism, which is attached to a pneumatic mast atop an ENG/OB van. (See Figure 12 for a typical mounting setup.) To ease the mounting of the RF Head (and legacy HPA if configured) to the Pan & Tilt, mounting adapter plates are available. The plate is first mounted to the Pan & Tilt with (4) 1/4-20x.750" flat head screws, then the RF Head (and legacy HPA if configured) are mounted to the adapter plate(s). For cases when the mounting adapter plate is not used, the hole pattern of the RF Head (and legacy HPA) base plate has been provided (See Figure 28). Note: The RF Head(s) should be mounted so that the heat sink fins are vertical during operation.

STANDBY Transmitter is in STANDBY until switched to another mode. Frequency synthesizer is locked on frequency. V. PRES. STBY This mode is only selectable when input is set to VIDEO. If no video is present, the transmitter will switch to STANDBY after a two-second delay (minimum). Use this mode to remotely place the transmitter into STBY when a video signal is removed. If the Test Generator is installed, the user may set Color Bars to be activated rather than have the unit go into STBY. See Section 5.4. V-BLK STB This mode is only selectable when input is set to VIDEO. If the camera is capped, or black video is present at the video input (no vertical interval signals present) the NewsCaster VT2 will switch to Standby within 30 seconds. If the black video or black burst is removed, the unit will switch to Standby in 2 seconds. When the video signal is reapplied, the unit will return to Normal mode within 2 seconds. If TEST GEN is installed, the user may select Color Bars to be activated rather than having the unit go into STBY. AUDIO (7) The AUDIO quick key is used for basic audio sub-carrier mode (LINE/AES) selection and gain changes. Note: You can NOT change Audio Sub-Carrier frequencies via this interface.

NewsCaster VT2 Operation M17-0002-00A Rev 4 51 User Manual Figure 29: NEWSCASTER VT2 Front Panel Controls and Indicators The gain or mode selection is made using the left or right arrow keys and edited using the standard editing procedure. Additional audio sub-carriers are selected with the up and down arrows. To edit sub-carrier frequency, refer to Settings in Section 5.4. The gain adjustment allows for ±6 dB of gain, and can be used to compensate for variance in line levels. Audio levels will be expressed in dBm when using analog modulation, and in dBu when in digital, per the following: PdBm + Gain -18 = PdBu 0.0 dBm = -18 dBu If LINE is selected, the unit accepts balanced 600-Ohm inputs at +8 dBm Analog (-10 dBu Digital). At 1 KHz input, headroom is +18 dBm Analog (0.0 dBu Digital). If AES is selected, the unit accepts data from the backplane AES port(s) and decodes the Group 1 audio from the SDI stream. If only two audio channels are configured, they will be the first channel in Group 1. Four LED’s indicate the status of the audio channel: GREEN: On and working - OK. GREEN Flashing: Over modulation. RED: Trouble indication. OFF: Off, or not configured. INPUT (8) The INPUT key brings up the Input Screen to select the mode of the input BNC connector. Press ENT, then use the up and down arrows to select the desired format. Press ENT to confirm entry. To return to the Standard Screen, press the Input key or wait 15 seconds. When analog modulation is selected, the input selections will be: Composite - The signal applied at the INPUT connector is routed through the internal low pass filter to modulate the output. Typically, this filter has a bandwidth of about 4.0 MHz for NTSC and 5.6 MHz for PAL. The NTSC filter selectivity ensures the higher frequency video components do not interfere with the 4.83 MHz audio subcarrier. SDI - SDI is converted to Composite via an internal circuit and then processed as a Composite signal. External 70 MHz FM - The input bypasses the modulator, and is routed directly to the heterodyne up-converter. When digital modulation is selected, the input selections will be: Input Video CH=**** 7,037.500MHz BAND=6-7G LOW 0.0dBm A 1 4 2 3 5 8 3 12 13 11 10 9 7 6 14
