• 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-ULR1 is a high-performance WHDI video transmission system that transmits uncompressed video and audio signals up to 1000m 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 authorized for indoor use. The 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 prioritized). The receiver’s 3G-HD-SDI and HDMI outputs may be used simultaneously.

Characteristics

• 1000m 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, means 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
  The 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 configuration

Operation

Transmitter

1. Connect the two omnidirectional 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 prioritize 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 firmly, that all other connections are stable, and that the batteries are suitable.
Antenna Positioning

Position the antennas on the 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 meters 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).
Choosing a Channel

1. To press and hold the “Menu” key with 2s, this unlock icon” “is shown on the OLED.
2. To press key “+” or “-” to select this desired channel and then press this “MENU” key to confirm

The system functions with 4 channels in the license-free 5 GHz ISM frequency band. Both the transmitter and the receiver have a frequency selector with positions from 1-4. Both the transmitter and the receiver have to be set to the same channel in or 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.
RSSI Display
The RSSI (Wireless Received Signal Strength Indicator) display shows the strength of the signal, allowing the operator to ensure the system is working reliably.

video signal
2-3 LEDs| Radio signal strength is normal and video quality is good
4-5 LEDs| Radio signal strength is very strong and video quality is very good

Establishing a Connection
Once all previous steps have been performed, turn on the transmitter and the receiver using the power switch. Once the transmitter recognizes a video input, the video format will show on the LCD screen.
It takes approximately 10-30 seconds for the transmitter to connect to the receiver. During this brief period, the receiver’s video displays “Waiting for connection”.

Maintenance

Please do not attempt to repair, modify or alter these devices under any circumstances.
Clean the devices with a soft, clean, dry, and lint-free cloth. Do not open the devices, they contain no user-serviceable parts.
Storage
The devices can be stored at temperatures between -20°C and 60°C. For long- term storage, please use the original transport case and avoid environmental conditions such as high humidity, dust, or excessively acidic or base surroundings.
Warning!
To ensure your own safety, please use only high-quality brand-name batteries, and follow the safety information and instructions provided by the manufacturer.

Troubleshooting

| Possible Cause| Possible Solution
---|---|---
No video output| Lack of power| Check power supplies of transmitter and receiver and ensure that all cables are
connected correctly and that there is sufficient power
Antennas| Ensure antennas are not damaged and are firmly connected
Video connection cable| Examine the transmitter’s “Video” LED display. If the LED is dark, check the HDMI or SDI connection cable
Frequency selection| Ensure that the transmitter and receiver are set to the same channel
Unsupported video format| Check your selected video format against the product’s technical specifications
Inadequate video quality| Connections| Check to ensure that all SDI or HDMI cables are firmly connected
The range is too great or the signal is obstructed| Check how many “RSSI” LEDs are lit on the receiver. For decent quality, at least 2-3 LEDs should be lit. If only one is lit, the signal is weak and the distance between transmitter and receiver should be reduced. Alternatively, obstacles between the devices should be removed or another channel selected
A radio signal is experiencing interference| Wait one minute then restart the transmitter and receiver or change the frequency channel
