Introduction
The Real Freedom Data Transmitter is an important Real Freedom wireless camera
system which allows you to remotely control up to six Real Freedom Camera Back Transmitters and to
provide camera control of most brands of broadcast camera.
Compact and fully weatherproof, the data transmitter simply connects with a single cable to any remote Real
Freedom Downconverter within the Real Freedom camera system. This enables the unit to be placed
anywhere without deploying additional infrastructure or cable. Once connected, intelligent connectivity
notifies the Real Freedom Receiver of the presence of the data transmitter within the network.
All setup and control functionality on the Real Freedom Data Transmitter is accessed from the intuitive
interface on the Real Freedom Receiver or remotely via an IP web page. External system wet and dry tally
connectivity is accessible on the rear of the Real Freedom Receiver.
The Real Freedom Data Transmitter provides full wireless camera control functionality when paired with the
Real Freedom Receiver, allowing RJ45 IP connectivity with operator/remote control panels. Up to six control
panels controlling cameras from differing manufacturers may be networked through a single UHF channel.
The Real Freedom Data Transmitter is fully compatible with the BSI Real Freedom Fiber Antenna Extender
for long distance remote operation to any receive points in the network.
Configuration examples
Example 1
This example shows a simple configuration with eight downconverters connected to a single receiver.
Figure 1: The data transmitter receives camera control data from a Remote Control Panel (RCP) via the Real Freedom
Receiver and transmits a GMSK-modulated narrow band UHF signal of between 430 MHz and 490 MHz. For maximum
flexibility, plug the data transmitter into any downconverter.

Example 2
This example shows networked camera control of six cameras over one UHF frequency.

Installation and configuration
Designed to be compact and fully weatherproof, the Real Freedom Data Transmitter connects to any remote
downconverter enabling the unit to be placed almost anywhere.
Overview
The main installation and configuration steps for a Real Freedom Data Transmitter are as follows:
1. Connect an antenna to the data transmitter.
2. Pole or surface mount the data transmitter.
3. Connect the data transmitter to a Real Freedom Downconverter attached to a Real Freedom Receiver or
Real Freedom Fiber Remote unit.
4.
Preparation
When planning the installation locations for data transmitters, you should take note of the following points:
•In general, you should install data transmitters in an area where they can be accessed easily by support
technicians. This area should also be out of reach or inaccessible to anyone that does not need to gain
access, such as fans at a sporting event or attendees at a conference.
•Ideally, place the data transmitters so that there is a line of sight from the transmitter to the
downconverter, and in a place where nothing will obstruct the path, such as dense metal objects that may
cause reflections and multipathing of the signal.

Unpack the data transmitter
Unpack the Real Freedom Data Transmitter and refer to the packing list to ensure that all items are included.
Report any missing items immediately to the Real Freedom Team.
Inspect the data transmitter for signs of damage. Report any damage to the Real Freedom Team.
Additional items required for installation
To install a Real Freedom Data Transmitter, you will require the following additional items:
•Antenna.
Either a BSI or third-party antenna with a standard N-type connector. Connect the antenna directly to the
transmitter via the antenna port.
•LEMO cable (LEMO 4-pin HGG0K-304-CLLP).
Use the LEMO cable to connect the data transmitter to a downconverter.
•Real Freedom Downconverter.
Connect the downconverter to a receiver or fiber remote unit using a coaxial cable with BNC connectors.
It is recommended that you use good quality 50 Ohm cable to connect to a receiver or 75 Ohm cable to
connect to a fiber remote unit.
Pole mount a data transmitter
The Real Freedom Data Transmitter is supplied with a removable mounting bracket which allows you to
mount the unit to a pole for temporary or permanent installation. The mounting bracket can be secured to
vertical or horizontal poles of between 1.44 and 2.68 inch (36.5 to 68 mm) in diameter.
Figure 3: Data transmitter mounting bracket (yellow)
Precautions
You should read these precautions before you pole mount a data transmitter.
•Before attaching a data transmitter to a pole or camera mount, ensure that the pole or mount can support
the weight of the data transmitter (0.97 lb. / 0.44 kg), antenna, attached cables, and any other devices
that you intend to attach to the pole. This is particularly important if you intend to attach the data
transmitter to the end of the pole.
•The data transmitter must be mounted vertically with the antenna port facing up.
•When attaching the mounting bracket to the data transmitter, do not overtighten the screws as it may
result in thread damage.
•The data transmitter becomes hot during operation. It is recommended that you mount the unit in a
well-ventilated area where it will not be touched accidentally.

Real Freedom | Data Transmitter Product Manual 10 of 22
Temporary installation
For temporary installation, use cable ties.
1. If not already attached, attach the mounting bracket to the back of the data transmitter using the four
screws (M3 x 8) provided.
Do not overtighten the screws as it may result in thread damage.
2. Pass at least two cable ties through the slots in the mounting bracket and around the pole.
3. Close and tighten the cable ties to secure the data transmitter to the pole.
Permanent installation
For permanent installation, use hose clamps.
1. If not already attached, attach the mounting bracket to the back of the data transmitter using the four
screws (M3 x 8) provided.
Do not overtighten the screws as it may result in thread damage.
2. Pass the hose clamps through the slots in the mounting bracket and around the pole.
3. Tighten the hose clamps to secure the data transmitter to the pole.
Installation using a ¼-20 UNC mount
Mount a data transmitter on a standard Manfrotto lighting stand, camera mount, repro arm, magic arm,
clamp, or Dado kit using a ¼-20 camera mount screw.
Figure 4: Data transmitter ¼-20 UNC mounting screws (yellow)
1. If not already attached, attach the mounting bracket to the back of the data transmitter using the four
screws (M3 x 8) provided.
Do not overtighten the screws as it may result in thread damage.
2. Either thread a ¼-20 screw through the screw hole in the mounting bracket into the hole in the mount or
screw the data transmitter onto the mounting screw.
3. Tighten to secure the data transmitter.
Surface mount a data transmitter
Depending on the installation type and site, you may wish to mount a data transmitter onto a vertical surface,
such as a wall.
1. If attached, remove the mounting bracket from the back of the data transmitter. The bracket is secured
with four screws (M3 x 8).
2.
masonry plugs into the holes, as necessary.
