Installing the PTX-PRO
This chapter describes how to install Transmitter (PTX-PRO).
CAUTION If you modify the product without authorization from Vislink, you will void
the warranty.
2.1 Unpacking the PTX-PRO
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.

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.

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.

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).
If you do not turn or press the control switch within 7 seconds, the screen reverts to the default
display. You can lock the display by pressing the Control switch; the display continues to update
the information. To unlock the display, press the Control switch again; the default screen
displays.
Use the CHAN and OFFSET Switches to select which channel to use. Verify the channel by
turning the Control switch clockwise to view the Channel Monitor screen, as shown in the
following example:
