2-2 Installing the PTX-PRO PTX-PRO User and Technical ManualWARNING - RF Power HazardWARNING The unit has high levels of RF power. Exposure to RF or microwave power can cause burns and may be harmful to health.• Remove power from the unit before disconnecting any RF cables and before inspecting damaged cables and/or antennas.• Avoid standing in front of high gain antennas (such as a dish antenna) and never look into the open end of a waveguide or cable where RF power may be present.The following guidelines for safe operation were derived from OET bulletin 65, August 1997, as recommended by the Federal Communications Commission (FCC).The PTX-PRO was designed to provide services to broadcast ENG users under CFR 74 subpart F and 74.601 TV pickup stations. This unit, operated without an antenna, will not create RF energy exceeding 1.0 mW/cm2, the FCC limit for exposure. Once connected to an antenna, the potential for harmful exposure will be greatly enhanced.In this situation, a certain distance from the radiator is to be maintained. Calculations need to be performed to understand what that safe margin for exposure is. This is known as the Maximum Permissible Exposure (MPE) limit.Calculations provided are for common antennas often utilized in the ENG environment. The following formula used is that suggested by OET 65.Calculating MPEEIRP = P * (10 ^ (G / 10)) = (antilog of G/10) * PP = RF power delivered to the antenna in mWG = Power gain of the antenna in the direction of interest relative to an isotropic radiatorR = distance to the center of radiation of the antenna in centimetersS = MPE in mW/cm² (milliwatts per square centimeters)ConversionsdBi to numeric gain = Antilog (dBi/10)Feet to centimeters = Feet * 30.48Centimeters to Feet = cm * .03284 π = 12.57User InputRF power delivered to the antenna = WattsAntenna gain (referenced to isotropic antenna) = dBiDistance from the center of radiation = Feet

An audio circuit can carry one analog balanced channel or two digital AES/EBU channels.A.3.3 MPEG Audio inputMPEG audio circuits must be configured in pairs with the MRC Radio Configurator software:•Audio 1 - LEFT/RIGHT or Digital AES/EBU.•Audio 2 - LEFT/RIGHT or Digital AES/EBU.A.3.4 AES/EBU Audio inputThe PTX-PRO only provides digital audio when operating in digital mode.In digital mode, the PTX-PRO receives a digital signal and routes the data to the MPEG decoder and then to the COFDM demodulator. The PTX-PRO audio switching circuitry connects the input of the MPEG decoder to the AUDIO connector. When configured for digital audio input (AES/EBU), the MPEG decoder provides two paired channels of digital data (+ and –), or four individual channels. All four circuits are balanced inputs, with each pair (+ and –) sharing one ground.A.4 Video ConnectionsThe PTX-PRO provides several video options on the front panel, using 75 Ohm BNC connectors, as described in the following table and in Section 1.1, Front Panel Controls, Indicators, and Connectors on page 1-2. Note If your PTX-PRO has only 3 BNC connectors on the front panel, your SDI and ASI share the same connector. A.5 Data ConnectionsThe PTX-PRO has an RS-232 data connector on the rear panel for the following purposes: • Remote Control using a STRATA RX Remote Control Panel• Radio Programming using a PC• Wayside Data communication.Operation Mode Connector SignalsSignal Input NTSC/PAL (525/625) or 70 MHz IFMonitor (output) 70 MHzSDI/SD/HD (input) SDI (525/625) or HD-SDIASI INPUT ASI inputSignalGround
A-6 PTX-PRO Specifications PTX-PRO User and Technical ManualTo access both radio and Wayside data, connect the DB-9 female RS-232 connector of the Multipurpose Data Cable (shown) to the PTX-PRO RS-232 connector. The Multipurpose Data Cable contains two DB-9 female connectors and one DB-9 male connector and contains band markers indicating connections to HOST, WAYSIDE, and RS-232 connectors. •The HOST DB-9 male connector is a Data Terminal Equipment (DTE) device that connects to a PC. When you connect the Multipurpose Data Cable to a HOST DB-9 male DTE device, you also must connect a null modem between the DTE device and the HOST male connector. If the HOST connector is connected to a DCE device, you cannot use a null modem cable, but you will need a straight pin-to-pin extension cable.•The WAYSIDE DB-9 female connector is a Data Communication Equipment (DCE) device connector that connects to a modem, GPS, etc. When you connect the Multipurpose Data Cable to a WAYSIDE DB-9 female DCE device, you also must connect a null modem between the DCE device and the WAYSIDE female connector. If the WAYSIDE connector is connected to a DTE device, you cannot use a null modem cable, but you will need a straight pin-to-pin extension cable.The following table shows programming connections using the Multipurpose Data Cable.Connector Pin Function1N/C2 Receive Data3 Transmit Data4N/C5GND6N/C7 Transmit Data (sends Wayside data to an external device)8 Receive Data (carries Wayside data from an external device)9N/C995511661166995555116699REDREDWHTWHT557766443322118899998811223344667755998811223344667755WHTWHTREDREDBLKBLKRADIO (M)RADIO (M)WAYSIDE (F)WAYSIDE (F)RADIO (M)RADIO (M)WAYSIDE (F)WAYSIDE (F)RADIO/WAYSIDE RADIO/WAYSIDE (F)(F) RADIO/ RADIO/WAYSIDE (F)WAYSIDE (F)1569
