目录
Thank you for choosing CVW's professional wireless HD audio
and video transmission product. Read the following precautions
carefully before using this product:
* Do not use this product for a long time in the sun or dusty place.
* Be sure to use this product within the temperature and humidity ranges.
Do not operate the product under vibration or strong magnetic fields.*
* Do not put conductive materials in the product vents.
* Do not open the product yourself without the guidance of our professionals.
* Before power-on, make sure that the adapter input voltage is AC110V-220V,
and that the output voltage and current meet the product specifications.
* Before power-on, make sure that the antenna is installed.
* This product is a 5GHz WIFI device. When there are devices with the same
frequency around, there may be mutual interference. In this case,
solve the problem by switching the frequency channel of the product.
Special Precautions
When installing the machine with the double-thread screw supplied with
the product, tighten the product with the fastening screw plate. Do not hold
the machine for rotary tightening to prevent the screw from being unable to
be removed from the machine.
The RS232 and Tally function interfaces of this product are non-standard
physical interfaces. If you need this function, communicate with the sales staff.

Product Features
BeamLink Duo is a set of 2TX-to-1RX full-HD audio and video wireless
transmission system. The 2 video channel transmission shares one wireless
channel and supports the highest video resolution up to 1080P/60Hz.
This system is based on 5G wireless network technology for transmission,
along with advanced 4×4 MIMO and Beam-Forming technology. Image
processing is performed using H.264 coding-decoding technology,
and the video quality is sharp and the latency is lower.
Brief Introduction
This product supports HD-SDI&3G-SDI input and output as well as HDMI full-HD
input and output, with the highest resolution of 1080P/60Hz. With the use of H.264
coding-decoding technology with high compression ratio and high definition,
the images have high definition, and the latency is as low as 70ms.
2 transmitters and 1 receiver share one wireless channel
Beam-Forming
Combined with 4×4 MIMO and Beam-Forming technology, this product has
advantages over other WiFi products in the market in terms of transmission
distance and image bitrate. Beam-Forming technology makes wireless signals
more concentrated and stronger in the direction from which they are transmitted
to the receiver, allowing them to transmit farther and be less susceptible to
interference from other signals, thus making them more stable.
Packing List
The following items are included in the product package
Power supply cable

Streaming Function
When using the functions in streaming mode, the transmitter needs to
switch to streaming mode. At this time, the word “RTSP” is displayed
on the transmitter ’s OLED display, the SDI and HDMI at the receiver have
no video output, and the image is transmitted to the streaming media
software through the LAN port of the receiver for decoding display.
The streaming mode depends on software decoding. Comply with lots
of streaming media software. The following is an example of common VLC
streaming media software:After the transmitter and receiver establish a
network connection, the transmitter network indicator is always on,
the receiver network connection is normal; the transmitter is connected to
the HDMI or SDI video source, and the receiver’s network port is connected
to the streaming device.
Take the VLC of the PC as an example. After running VLC, select to turn on
the network stream.Fill in the address “rtsp://corresponding transmitter
encoding board IP address/media/live/0”. Click “Play” to start streaming.
Note that the transmitter must be connected to the video source, and the
IP address of the terminal streaming device (such as a computer) must be
the same network segment as the IP address of the encoding board.
Otherwise, the streaming will fail.

(TX-to-RX<2m)
Precautions
a. Do not plug in or pull out the HDMI cable of the transmitter and receiver
during normal use.
c. When the OSD prompts that code matching fails after trying code matching,
reboot the transmitter and receiver to see whether they can be connected
normally. Perform code matching again when it is still unable to be
connected after restarting.
d. When there is no video source output since a blank screen appears during
the receiver output after switching the video source resolution, pull out
and then plug in the HDMI cable of the transmitter or receiver. If the HDMI
cable cannot be recovered after removal and insertion, power off and
restart the transmitter and receiver.
e. When the network cannot be connected for a long time after switching
frequency channel, reboot the transmitter and receiver.
f. When the transmitter and receiver devices are connected normally,
there is no output on the monitor at the receiver, or the video output is
abnormal, re-plug the HDMI cable of the receiver and check whether the
monitor is on standby. If it is still unable to output normally after the above
operation, try to replace the display device.
2. If there is a picture jam or mosaic during use, it is generally caused by
interference in the network. Therefore, try switching the network frequency
channel to avoid the interference band. The frequency switching
operation refers to the frequency switching operation instructions.

b. Connect the transmitter to the video source and connect receiver to
a monitor via HDMI and then power on the transmitter and receiver.
1. If transmitter or/and receiver use HDMI cable:(a~f)
25 26

3. When using the device, be sure to install the antenna before turning on the
power. Failure to do so may result in damage to the device.
4. When used, the surrounding environment will affect the quality of wireless
transmission. Poor operating environment may cause image sound disorder,
such as picture pause, noise, etc. Therefore, pay attention to the following:
Walls, large metal plates, and appliances can affect wireless transmission.
Try to avoid using in these environments.
In case of using in crowded conditions, the transmitter and receiver should
be raised as high as 1.5-2m or more.
If a 5GHZ wireless device is used nearby, it may also cause interference to
wireless transmission. Such issue can be solved by switching the frequency
channel. It is recommended to switch the product frequency to the
intermediate frequency in the case of interference.
Do not place the transmitter and receiver in a metal shelf, which will
affect the wireless transmission. If it is unavoidable, consider leading
the antenna out.
The transmitter and receiver are 1.5-2m above the ground. The antenna
is fan-shaped and facing forward, and the transmission effect is the best.
