Carefully unpack your new equipment to avoid damage.
• Locate all parts and accessories and verify that they are listed on the packing list.
Note DO NOT discard the container or packing material until you have inspected the
equipment and are sure there is no shipping damage. The container and
packing must be available in case you need to file a damage claim with the
shipping carrier.
• Inspect the equipment for damage and that it is clean and dry.
• Inspect the cables, connectors, switches, and displays to ensure that they are not
broken, damaged, or loose.
If you discover damage after unpacking the system, report the damage as follows:
• Immediately file a claim with the shipping carrier.
• Forward a copy of the damage report to Vislink Customer Service.
• Contact Vislink Customer Service to determine the disposition of the equipment. See
Section 4.1, Getting Support for Your PTX-PRO on page 4-1.
2.2 Preparing to Install the PTX-PRO
The following sections describe the things you should consider before installing the DXL8000.
2.2.1 Operating in Safety
CAUTION Ensure that the power being supplied matches the power required by
the equipment. You can find power ratings for equipment on a rating
plate, usually on the rear panel. 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.
2-2 Installing the PTX-PRO PTX-PRO User and Technical Manual
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
Installing the PTX-PRO 2-3PTX-PRO User and Technical Manual
Calculation steps:
1. [P] RF power input. Watts to milliwatts = Watts * 1000
2. [G] Antenna gain dBi. Numeric gain = Antilog (dBi/10)
3. [EIRP] Multiply P * G
4. [R] Centimeters to feet = Centimeters * .0328
5. Square R
6. Multiply R² * 4π
7. [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.

2.2.2 Powering and Grounding the PTX-PRO
For safe operation, all equipment must be properly grounded.
• Connect the unit to a common (vehicle or aircraft) ground.
• Make the ground wire as short and straight as possible.
CAUTION Be sure the equipment grounding follows applicable electrical codes.
Never modify a grounded power plug to connect to an ungrounded
receptacle.
Ensure that the power being supplied matches the power required by
the equipment. You can find power ratings for equipment on a rating

Operating the PTX-PRO
This chapter describes how to use the PTX-PRO Transmitter (PTX-PRO).
3.1 Powering Up
Before powering up the PTX-PRO, make sure to connect the cables to the correct connectors
and fully mate and lock the connections.
CAUTION Make sure the power supplied matches the power required by the unit.
When you set the PWR switch to I (on), the following sequence occurs:
1. The PWR LED above the PWR switch illuminates and changes colors from red, to green,
to amber, and finally to green and should remain green.
2. The alphanumeric display lights up and displays a self-test screen, then the version of
the firmware, and finally the default screen. The PTX-PRO uses the last settings in use
when power was turned off.
Test the performance of your PTX-PRO by setting up a link and transmitting and receiving video
and audio. If the PTX-PRO does not power up normally, see Chapter 4, Troubleshooting.
3.2 Using the Display Screen
The screen on the PTX-PRO transmitter displays the values of the selected preset and the
output power. For example:
Preset #1
0.00W C 1
The Control switch lets you monitor status and set functions, displayed on the PTX-PRO
screen. The Control Switch cycles through information when you turn it clockwise (for
Monitoring information; see Section 3.3) or counterclockwise (for Setting parameters; see
Section 3.4).

3.3 Monitoring PTX-PRO Operations
Review Monitor screens by turning the Control switch clockwise. The sequence of screens
depends on the mode.
• Analog IF mode routes a 70 MHz IF signal through the transmitter to the Signal input
connector.
• ASI In mode supplies an ASI stream to the RF output monitor connectors.
• COFDM mode supplies a 70 MHz CODFM IF to the RF output and monitor connectors.
• Ext. IF mode supplies a 70 MHz IF input signal to the Signal Input connector of the
transmitter.
• LMS-T mode uses a single carrier modulator and supplies a configurable LMV-S signal
to the RF output and monitor connectors.
The following table shows the Monitor screen sequences of each mode.

PTX-PRO Specifications A-5PTX-PRO User and Technical Manual
The PTX-PRO provides a maximum of four audio circuits. 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.
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 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.

A-6 PTX-PRO Specifications PTX-PRO User and Technical Manual
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.
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.

• Device Server
Also called Serial-to-Ethernet converters, the device
servers take serial RS-232 data and convert it to the
format needed for an Ethernet network.
You can use a Lantronix UDS-10 because it accepts data
via a DB-25 connector, and connects to the network via an
RJ-45 connector.
• Interface Cable
This cable connects to
the PTX-PRO data
connector (DB-9) on one
end and connect to the
device server on the
other (for example, a
DB-25 connector in the
case of the UDS-10).
This is a custom cable
which you will have to
fabricate.
