Safety Precautions
The Video Transmission System
Do not block or obstruct air vents, as this may cause short circuits, fire or electric
shocks. Turn the device off immediately if it comes into contact with liquids.
The Power Supply
The device may be used with batteries or AC-DC power supplies of the voltage
specified on the device or in the enclosed documentation.
If batteries are used, please ensure that the batteries are compatible and have no
cracks or leaks.
Please use the enclosed power adapter. When using a third-party power adapter,
please ensure that the adapter conforms to the specifications of the device and has
the correct polarity.
Remove the power supply if:
-The device will not be used for an extended period of time
-The power cable is damaged
-The exterior of the device is damaged.
Operating Environments
-Due to current regulations governing the use of radio-based systems, this
device is authorised for indoor use with the pre-installed channels five and six
(by law, “indoor use” is defined as use in a building including places
assimilated thereto in which the shielding will typically provide the necessary
attenuation).
-Do not place the device on metallic surfaces, to ensure effective data transfer.
-Do not place the device on dirty or damp surfaces.
-Do not use the device in the proximity of water or in high humidity, near open
fires or gas pipes, or near electrical mains.

Overview
The DC-Link-LR1 is a high-performance WHDI video transmission system which
transmits uncompressed video and audio signals up to 700m with low latency
(1 ms delay).
Due to the conscious decision not to implement the DFS (Dynamic Frequency
Selection) System, which is compulsory for outdoor use, the device has a longer
range, greater stability and better usability than comparable systems, but is only
authorised for indoor use.
Transmitter and receiver both have 3G-HD-SDI and HDMI connectors (Plug & Play).
When a video source is attached, the transmitter automatically selects the input (SDI
is prioritised). The receiver’s 3G-HD-SDI and HDMI outputs may be used
simultaneously.
Four receivers may be used for every transmitter.
The DC-Link-LR1 Video Transmission System is compatible with the DC-Link-CLR1
Video Transmission System.

Characteristics
!700m Range
Transmission ranges of up to 700m are possible with good line-of-sight and optimum
antenna positioning
!Rapid and Reliable Connectivity
The decision not to implement the DFS System compulsory for outdoor use, as well as the
preinstalled transmission channels, mean there is no need for complex pairing procedures. In
addition, transmission stability is increased
!Real-Time Transmission
With a latency of less than 1ms, the system is suitable for live monitoring applications
!Uncompressed Transmission
10-bit, 4:2:2 transmissions via 3G-SDI and HDMI without format conversion
!Supports Formats up to and including 1080p 60Hz
!2- Channel Audio Transmission
Embedded audio transmission on CH1 & CH2 via SDI and HDMI, incl. formats such as Dolby
TrueHD, DTS-Master etc.
!License-free Frequency Band
Functions in the license-free 5GHz ISM frequency range from 5.1-5.9GHz
!Multicast Support
1:1 or 1:n transmissions with up to four parallel systems
!Metadata- and Timecode Transmission
!AES-128 Encryption
!Metal Casing
Transmitter and receiver are extremely durable
!Variable Input Voltage
Input voltage range from 6.5-16.8V DC allows the system to be operated with a variety of
batteries or power supplies
!Status Displays
Status displays for DC power, video and RSSI signal strength
!Mount
1/4" tripod mount
!Battery Adapter Plate
Delivered with NPF/V-Mount battery plates as standard

Operation
Transmitter
1. Connect the two omni-directional antennas to the RP-SMA male connectors.
2. There is a ¼“ tripod mount at the base of the transmitter if required.
3. Use the enclosed 4-pin male-to-D-TAP cable to connect to a power supply with a
suitable voltage.
4. In order to comply with local laws, please ensure you select the appropriate
frequency for your country (more information on page 10).!
Receiver
1. There is a ¼“ tripod mount at the base of the receiver if required.
2. Use the enclosed 4-pin male-to-D-TAP cable to connect to a power supply with a
suitable voltage.
3. Ensure you have selected the frequency that corresponds to that of the
transmitter.
Signal Distribution
Connect the camera’s SDI or HDMI output to the transmitter’s SDI or HDMI input. If
both SDI and HDMI inputs are active, the transmitter will prioritise the SDI signal.
Connect the receiver’s SDI or HDMI output to the SDI or HDMI input of the
monitoring/recording device. During active transmission, both the SDI and the HDMI
output on the receiver may be used simultaneously.
Ensure that the antennas are connected firmly, that all other connections are stable,
and that the batteries are suitable.

Operation
Antenna Positioning
Position the antennas on transmitter and receiver at right angles as shown in the
illustration. This ensures the best possible RF performance.
Install the transmitter and the receiver as high as possible (at least 1.5 metres above
ground level), to maintain a good line-of-sight. During operation, try to keep the
transmitter and the receiver at similar heights.
Avoid obstacles such as walls, trees, water and steel structures between transmitter
and receiver as much as possible.
The connection is at its strongest when the flat surfaces of the transmitter and
receiver face each other (see illustration).

ENGLISH

Operation
Choosing a Frequency
The system functions with 10 channels in the license-free 5 GHz ISM frequency band.
Both the transmitter and the receiver have a frequency
selector with positions from 0-9. Only channels 5 & 6
are permitted for use within Europe.
Both the transmitter and the receiver have to be set to
the same channel in order to communicate with each other. If several systems are
used at once, then the channels used should be as far from each other as possible to
avoid interference or a reduction in range. A maximum number of 4 systems
simultaneously is recommended.
Authorised Channels by Country (Selection)
Please ensure you are aware of the local regulations regarding radio frequencies in
the relevant country before operating the system.
