NewsCaster VT2 Description M17-0002-01A Rev 0.0 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 GHz 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. 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 Rev B 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 10 Watt 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 GHz 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 M17-0002-01A 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.
NewsCaster VT2 Features M17-0002-01A Rev 0.0 16 User Manual 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 solid tone. The right channel will be a pulsed tone. 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. 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 & 13 GHz US frequency bands, and/or other bands as required internationally, from 1 GHz to 15.5 GHz. 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. This cable carries the 70 MHz IF and the Control Data signals—and in a typical system, carries 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 +48 volts. 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 . The Newscaster will on occasion, be used to replace systems that use 50  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  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.
NewsCaster VT2 Features M17-0002-01A Rev 0.0 17 User Manual 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. • Optional Four Form C Relay contacts controlled from the Control Unit.

NewsCaster VT2 Installation M17-0002-01A Rev 0.0 29 User Manual 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 re-shipment, as needed. 4.2 PRE-INSTALLATION CHECKOUT NOTE: The NEWSCASTER VT2 Control Unit and RF Head conventionally are connected with either a single TNC Coax or Triax cable. In a typical system, +48 VDC is fed to the RF Head through this cable along with the 70 MHz IF and Control Data signals. However, there is a distinct different between the two types of cables. For the TNC Coax, the signals are diplexed onto the center conductor of the cable. For the Triax, the signals are diplexed on the inner shield of the cable. WARNING! DO NOT connect the wrong type cable to the wrong type unit, since doing so will damage one of the connectors and result in intermittent failures. Connect the NewsCaster VT2 IF output to the RF Head via an appropriate IF cable. (Refer to Table 7.) Connect the RF output of the RF Head through a 30 Watt, 30 dB attenuator to a spectrum analyzer and observe the output frequency on the analyzer display. Note that the frequency and level correspond directly to the LCD display on the front panel of the VT2. NOTE: The power level displayed on the LCD is for indication only. 4.3 CABLES AND CONNECTORS Detailed drawings and pin-outs of the NewsCaster VT2 cables and connectors are shown throughout this section. Please contact Nucomm Customer Service if additional detail is required. 4.4 CONTROL UNIT MECHANICAL INSTALLATION The NewsCaster VT2 Control Unit is shipped pre-assembled. Mount the Control Unit in a standard 1RU E.I.A. rack space, using all 4 rack screws.

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) – (Serial Digital Interface) This signal combines both digital audio and digital video into one signal. • ASI IN – (Asynchronous Serial Interface) Similar to SDI, this signal combines both digital audio and digital video into one signal. • ASI OUT – (from the internal encoder) The Output ASI connector provides an output of the encoded MPEG stream, and can be used to feed a satellite modulator or external transport stream multiplexer. • Video (Input) – It is an analog video signal that is proportional to the received signal deviation. 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 70 MHz” 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. (Refer to Figure 6, Detail 2). Note: When “External 70 MHz” input is selected, the 70 MHz out is a loop-through only. Figure 7: Control Unit, Audio Connector
NewsCaster VT2 Installation M17-0002-01A Rev 0.0 33 User Manual 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.) 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. These are: (a) Modulated 70 MHz signal (b) Inter-unit control data (c) +48VDC for the RF Head. For cases when an existing non-conforming IF cable that cannot handle +48 VDC, the AUX Power option must be fitted on, which 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 +48 VDC 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 – 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 Figure 8 for pin-out.

NewsCaster VT2 Operation M17-0002-01A Rev 0.0 51 User Manual Mode (6) The MODE key is used to select from the following operating modes: • Normal: Transmitter is active, with or without a video (or composite) input signal. • Standby: Transmitter is in STANDBY until switched to another mode. Frequency synthesizer, however, 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 5.3.) • V-BLK STBY: 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 the TEST GEN function 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 FM audio mode, line/AES selection and gain changes. After the Audio Button is pressed, the Audio options will appear. The user must then select the desired audio channel. Once the desired audio channel is selected, the arrow keys are used to scroll through the parameter list. The gain or mode selection is made using the left or right arrow keys and edited using the standard editing procedure. Additional audio channels are selected with the up and down arrows. To edit sub-carrier frequency, refer to Section 5.4.1. Note: When changing the sub-carrier frequency range, the values are altered by highlighting the character and using the arrow keys to increase or decrease the value. To enter the value, move the cursor to the “M” (last character) and press the “ENT” Button. 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
NewsCaster VT2 Operation M17-0002-01A Rev 0.0 52 User Manual If LINE is selected, the unit accepts balanced 600  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) Pressing the INPUT key, brings up the Select Input Screen. This allows the user to decide upon the type of input to be fed to the unit. 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 and sent to the FM modulator. (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 sub-carrier.) 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: Composite - In this mode, the input signal is passed through the MPEG Encoder and converted to digital, then routed to the digital modulator. SDI - The Input is routed through the MPEG Encoder, and then to the digital modulator. External 70 MHz Digital - The input bypasses the modulator, and routes to the heterodyne up-converter. ASI - Input bypasses the Encoder and goes to the digital modulator. The ASI rate must be at or below the maximum digital modulation rate. TEST GEN (9) This key allows editing of the 16 character ID, and selection of the waveform display. This is only selected when the input type is set to “VIDEO”. The LED is illuinated when the Generator is active.
NewsCaster VT2 Operation M17-0002-01A Rev 0.0 53 User Manual When TEST GEN is enabled, the green LED is lit and the LCD displays the current pattern and ID. The menu will time-out after 30 seconds. Pressing TEST GEN a second time, disables the TEST GEN function. ANTENNA CONTROL (10) The SELECT key is used to change the antenna polarization. PAN &TILT (11) When Pan & Tilt is pressed, the Red indicator LED is lit to indicate P/T power is enabled. Any joystick movement will move the antenna in that direction. A display for P/T elevation and aximuth is available. When operating the Pan & Tilt, the antenna movement MUST also be physically monitored to reduce the danger of hitting power lines, etc. When the desired position is reached, press Pan & Tilt again to disable power to the motor and reduce the possibility of unintentional antenna movement. ANTENNA SELECTION (12) This key toggles between Omni or Directional for antenna selection. If no Omni is connected, then this function should be disabled. (See Options in Section 5.3.) HI/LOW RF POWER (13) This key selects whether the unit will operate in HI or LOW power mode. MODULATION MODE (14) This key selects whether the unit will operate in Analog or Digital mode. 5.3 UPPER LEVEL MENU The Upper Level Menu allows the user to access sub-menus in order to vary the operational parameters of the unit. Refer to Figure 29 and Figure 30 for tree diagrams of the menu system. To enter the Main Menu, hold () and press “ENT”. To select a sub-menu, move the cursor to the desired item and press “ENT”.

(Alarms are listed by priority and not by occurrence.) Use the Left and Right Arrow Buttons to scroll through all the options.
NewsCaster VT2 Operation M17-0002-01A Rev 0.0 54 User Manual INPUT MENU The Input Menu is used only to set the type of signal that is to be inputted to the unit. • Composite • SDI • 70 MHz • ASI MODULATION MENU The Modulation Menu allows the user to change any of the associated analog or digital parameters. The Modulation Menu is broken down into two sections: Mode and Parameters. (Refer to Figure 7.) Mode Mode allows the user to select the Digital Mode of Operation (COFDM, DVB-S, and VSB). Parameters The Parameters Sub-menu has Analog (FM) parameters and Digital (COFDM, DVB-S, and VSB) parameters. FM PARAMETERS The FM (analog) parameters are divided into two sections: Audio and Video. FM Audio Settings Under the FM Audio sub-menu, there are four channels to choose from. They are: • SC1L (Audio 1 Left) • SC1R (Audio 1 Right) • SC2L (Audio 2 Left) • SC2R (Audio 2 Right) Each has an identical set of parameters. 1. Input - selects the type of audio input source going to the VT2 (Line [analog source], Tone [self-generated source], AES/EBU [digital source], and Off. 2. Insertion - adjusts the input audio level from –40 dB to –20 dB. 3. Gain - adjusts the audio output level from –6 dB to +6 dB. 4. Freq - allows the user to select the FM Audio Channel sub-carrier bandwidth. FM Video Settings Under the FM Video sub-menu, the operator may change three parameter settings. These are: 1. Inverse - which can set the video waveform to Normal (in-phase) or Inverted (180° out-of-phase). 2. Emphasis - allows the operator to switch between Video Emphasis Mode or Video Flat Mode. (In Video Emphasis Mode, the lower video frequencies are rolled-off, while high frequencies are amplified.) 3. Filter - sets the bandwidth of the video filter. This is used to ensure that the audio sub-carriers do not cause interference with video signal when required. The choices are: Bypass (filter off) or bandwidths of 3.9 MHz, 4.5 MHz, 4.75 MHz, or 5.6 MHz.
NewsCaster VT2 Operation M17-0002-01A Rev 0.0 55 User Manual COFDM PARAMETERS The COFDM (digital) parameters consists of five options: 1. Power - toggles the COFDM modulator “On” or “OFF”. 2. Constellation - provides several different methods of modulating the signal for transmission: • QSPK • 16-QAM • 64-QAM 3. Code Rate Under the Code Rate sub-menu, the user can set the amount of error correction. The Code Rate (as well as Guard Interval, Bandwidth, and Modulation) is instrumental in setting the proper Data Rate. The options for the Code Rate sub-menu are: • 1/2 - code rate used for channels with the greatest amount of noise. • 2/3 • 3/4 • 5/6 • 7/8 - code rate used for channels with the least amount of noise. 4. Guard Interval - COFDM carriers have a precise spacing between each frequency. This spacing ensures that only one carrier is addressed at a time, and that no crosstalk exists between carriers. Under the Guard sub-menu, the user can set the amount of delay interval between symbols. The options for this sub-menu are: • 1/32 - shortest delay between symbols. • 1/16 • 1/8 • 1/4 - longest delay between symbols. 5. Bandwidth - The bandwidth is the span or width of a carrier frequency. Under the Bandwidth sub-menu, the user can select the size of the carrier bandwidth. The options for this sub-menu are: • 6 MHz - usually used for a “split-channel” due to having the faster “band re-growth” drop-off rate.

A parameter may have been inadvertently missed or set to the wrong value. If that doesn’t solve the problem, then make a check of all internal cabling of the NCVT2 Control Unit, ensuing that all cables are properly seated and fastened tightly (if applicable). Also check to see if all jumpers (if any) have been installed properly. Finally, check all power supply voltages of the Control Unit, ensuring that they are within their specified limits. WARNING!!! To minimize the possibility of Electro-Static Discharge (ESD) damage, ensure that all equipment is properly grounded and that you are using ESD protective practices and equipment! NOTE: With COAX / TNC cables, the +45 VDC is on the center pin of the cable. For TRIAX cables, the +45 VDC is carried on the inner shield instead.
