1. Introduction to the CT2020HD
1.1 Preliminary Remarks
The present manual is provided for users and operators of the CT2020HD Transmitter.
It is intended to support the installation, operation, maintenance and daily use of the
unit in general.
The manual should be kept with the CT2020HD Transmitter and may be consulted
when questions occur. If problems should remain after you have read the manual
carefully or if you have any further questions concerning the functionality or operation
of the Transmitter, please contact the Customer Service.

Video Inputs
The CT2020HD accepts only HDSDI information at the input:
1.3 Description
General Information on D-ENG (Digital Electronic News Gathering)
The introduction of the DVB standard established the basis for digital broadcast video
transmission making efficient use of the available bandwidth. Powerful compression
algorithms allow a reduction in the amount of data to be transferred, while
maintaining the high quality standards for video and audio signals used in broad-
casting applications. New modulation techniques and error correction algorithms
ensure a secure signal transmission even when the transmission conditions are poor.
The DVB-T standard was established for terrestrial digital TV broadcasting, in
particular considering the difficult conditions of radio transmission. The highly efficient
OFDM multicarrier modulation procedure enables transmission without interference
even under multipath propagation conditions occurring with non-directional
transmission or reception. Practical experience soon has proved that the DVB-T
standard guarantees ruggedness of transmission to an extent even allowing mobile
reception.
Increasing miniaturization, in particular of MPEG encoders and OFDM modulators,
enables using the DVB-T standard for mobile portable transmission systems.
Previous analog FM systems were adversely affected by signal reflections directly
resulting in video and audio interferences. Such effects do not occur when the digital
ENG system (D-ENG) is deployed. Even mobile transmission from moving vehicles or
the use of omni-directional antennas on the transmitting or receiving side does not
impair the picture or sound quality at all, opening a completely new range of
applications in TV production and news gathering.

2. Installing the Equipment
2.1 Safety instructions
Warning
The regulations of VDE0100 must be observed for
installation and operation of the unit.
Caution
•Establish all other connections before starting the unit by
connecting it to 12VDC. Essential a valid video signal must be
connected to the desired input before power on the CT2020HD.
•When you connect the CT2020HD as described in the following
sections, make sure that the "Caution" instructions given there
are observed.
•Make sure that there is sufficient air circulation to ensure
adequate cooling of the unit.
External forced ventilation may be required if the unit is installed
in a rack or cabinet.

Chapter 3: Options and Upgrades
2.2 Connectors
1 Input connector of the CT2020HDFigure
•RF Connector
The RF output signal of the Low-Power Amplifier is fed out at the N(f)
connector on top of the unit.
The CT2020HD provides a RF output of about 400 mW (+26dBm).
Connecting Signal Sources
The Video signal supplied by the camera has to be applied to the HDSDI BNC(f)
connector of the transmitter.
The Audio signal supplied by the camera has to be applied to the Audio in 5pol Lemo
connector of the transmitter.
Connecting the RF Output
A Omni directional antenna with N(m) connector can be directly mount at the RF out
socket.
Connecting the UHF Data Input (optional)
A UHF antenna with SMA (m) connector can be directly mount at the UHF in socket.

Connecting the 12VDC Supply Voltage
Caution
When using a battery or power pack, make sure that the maximum
supply current is at least 3A and the output voltage matches the
input voltage range of the CT2020HD.
Failure to comply with these requirements may cause fatal
damage to the battery/power pack and/or CT2020HD.
Battery Powered Operation of the CT2020HD
Many types of batteries are available on the market and we tried to support the best
ones.
2.3 Shut-Down
Caution
To shut-down the unit, first disconnect it from the 12VDC supply
voltage.
After disconnection from the supply voltage by removing the battery or disconnecting
the 12VDC supply cable, the other connecting cables can be removed from the unit.
