Safety Precautions
The Video Transmission System
Do not block or obstruct air vents, as this may cause short circuits, re 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 speci-
ed 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 specications 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 ve and six (by law,
“indoor use” is dened as use in a building or similar location 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
res or gas pipes, or near electrical mains.
In all EU member states, operation of 5150-5250MHz
is restricted to indoor use only.

Overview
The DC-Link- ULR1/LR2 is a high-performance WHDI video transmission system which
transmits uncompressed video and audio signals up to 1200m(ULR1)/700m(LR2) with
low latency (1 ms delay).
Due to the conscious decision not to implement DFS (Dynamic Frequency Selection),
which is compulsory for outdoor use, the device has a longer range, greater stability
and better usability than comparable systems, t
Transmitter and receiver both have 3G-SDI and HDMI connectors (Plug & Play). When
a video source is attached, the transmitter automatically selects the input (SDI is priori-
tised). The receiver’s 3G-SDI and HDMI outputs can be used simultaneously.

Characteristics
• 1200m (ULR1)/700m (LR2) Range
Transmission ranges of up to 1000m 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
• 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 9.0-18.0V 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
• Plug-and-Play Design
Ready to use without the need for complex conguration
• 1 Year Manufacturer’s Warranty

Operation
Transmitter
1. Connect the two omni-directional antennas to the 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.
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 can be used simultaneously.
Ensure that the antennas are connected rmly, that all other connections are stable,
and that the batteries are suitable.

Antenna Positioning
Position the antennas on transmitter and receiver as shown in the illustration. This
ensures the best possible RF performance.
Install the transmitter and the receiver as high as possible (at least 2 metres above
ground level) to maintain a good line-of-sight. During operation, try to keep the trans-
mitter and the receiver at similar heights.
Avoid obstacles such as walls, trees, water and steel structures between transmitter
and receiver.
The connection is at its strongest when the at surfaces of the transmitter and receiver
face each other.
