Ensure that the electrical supply is protected by over-current protection devices as required by the applicable electrical codes. If necessary, consult a licensed electrician. PTX-PRO User and Technical Manual Installing the PTX-PRO 2-1 WARNING - RF Power Hazard WARNING 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 MPE EIRP = P * (10 ^ (G / 10)) = (antilog of G/10) * P P = RF power delivered to the antenna in mW G = Power gain of the antenna in the direction of interest relative to an isotropic radiator R = distance to the center of radiation of the antenna in centimeters S = MPE in mW/cm² (milliwatts per square centimeters) Conversions dBi to numeric gain = Antilog (dBi/10) Feet to centimeters = Feet * 30.48 Centimeters to Feet = cm * .0328 4 π = 12.57 User Input RF power delivered to the antenna = Watts Antenna gain (referenced to isotropic antenna) = dBi Distance from the center of radiation = Feet 2-2 Installing the PTX-PRO PTX-PRO User and Technical Manual Calculation steps: 1. 2. 3. 4. 5. 6. 7. [P] RF power input. Watts to milliwatts = Watts * 1000 [G] Antenna gain dBi. Numeric gain = Antilog (dBi/10) [EIRP] Multiply P * G [R] Centimeters to feet = Centimeters * .0328 Square R Multiply R² * 4π [S] Divide (R² * 4π) into EIRP S = Power Density in milliwatts per square centimeters. Note At frequencies above 1500 MHz, S must not be greater than 1. Reference FCC OET Bulletin 65, August 1997 - Evaluating Compliance with FCC Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields The following graph and associated table show the permissible exposure distance for various antennas. Graphs and data will vary, based on the actual transmitter, output power, frequency, and antenna utilized. One plot provides the permissible output of the transmitter for digital modulation, and the other plot for analog modulation. This information is provided, in accordance with the requirements set forth by the FCC, as a guide for you assuming that users of this equipment are licensed and qualified to operate the equipment per the guidelines and recommendations contained within the product user guides and in accordance with any FCC rules that may apply.

Each audio circuit is a 3-wire balanced circuit capable of carrying one tone or voice signal. An audio circuit can carry one analog balanced channel or two digital AES/EBU channels. A.3.3 MPEG Audio input MPEG 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 input The 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 Connections The 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. Operation Mode Connector Signal Input NTSC/PAL (525/625) or 70 MHz IF Monitor (output) 70 MHz SDI/SD/HD (input) SDI (525/625) or HD-SDI ASI INPUT ASI input Signal Ground Note Signals If your PTX-PRO has only 3 BNC connectors on the front panel, your SDI and ASI share the same connector. A.5 Data Connections The 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. PTX-PRO User and Technical Manual PTX-PRO Specifications A-5 To 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. RADIO (M) RADIO/ WAYSIDE (F) WAYSIDE (F) RADIO/WAYSIDE (F) RED WHT BLK WHT RED RADIO (M) WAYSIDE (F) 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.
