Product Overview
BeamLink-Duo Plus is a multi-channel wireless video transmission system based on a
5GHz band that supports 2-channel wireless video and audio transmission, Tally, and
pan-tilt-zoom (PTZ) camera control, with video resolution up to 1080p/60Hz. It is widely
used in live streaming, TV and filming, multimedia education, etc.
Product Highlights
Two channels of transmission only occupy one wireless channel
Supports simultaneous two-channel video and audio signals transmission, and each
video channel’s highest resolution can reach 1080p/60Hz. These channels use the
same wireless channel, greatly saving spectrum resources.
High-quality and low-latency video frame
Supports HD-SDI & 3G-SDI input and output, supports HDMI full HD input and output,
highest resolution can reach 1080p/60Hz. Compared with H.264 technology, H.265
technology offers higher color reproduction, showcasing the image more colorful.
4* 4 MIMO and Beamforming technologies make the wireless beams more concentrated,
signal-to-noise ratio higher, which result in a farther transmission distance and a stronger
interference immunity.

Packing List
Important Reminders:
* All the transmitters come with an NP-F battery holder and are preinstalled with a
V-mount connector; the receiver is preinstalled with a battery slot and V-mount
connector.
* The transmitter can be attached to the camera handpiece or handle area via magic arm.
* The receiver can be fixed on the light stand or tripod via 1/4 or 3/8 screw hole.
System Connectivity Diagram
BeamLink-Duo Plus consists of 2 transmitters and 1 receiver. All transmitters support
one HDMI and one SDI input. The receiver support 2 HDMI and 2 SDI outputs. It not
only can control Tally, RS232/RS422-enabled functions like camera control, but also
can do implement RTSP streaming via LAN port. See the diagram below:
Point-to-Point Mode and RTSP Streaming Mode
The system supports point-to-point mode and RTSP streaming mode working
simultaneously, which means that HDMI, SDI, and LAN ports can output video
signals at the same time. In so doing, this solution can be widely applied to
different scenarios.
RS232/422 Transparent Transmission
The RS232/422 port can support the pan-tilt-zoom (PTZ) camera control.
* If you need Tally function, please contact our sales staff and provide them with your
switch console interface’s model and definition to make customization more convenient.
* If you need RS232/RS422 function, please contact our sales staff to confirm and
provide them with the model and definition for your PTZ camera and controller
interface to make customization more convenient.

Whether all the antennas are positioned at the ideal angle or not.
Transmission Distance
Factors to Influence Distance
The system supports low gain mode and high gain mode.
For wireless transmission bitrate, as bitrate increases, transmission distance decreases.
The system supports H.265 technology that ensure high quality transmission through
a bandwidth of 4Mbps.
Metal, walls, other objects and human body that block wireless transmissions
downgrade signal strength.
Whether there is any other wireless interference or not.
Transmission Distance and Gain Mode Selection
The corresponding relationship between the maximum transmission distance,
installation height, and wireless gain mode is described below in an open and
unobstructed scenario. The following data is the approximate distance obtained
during actual tests.

(Prioritizing use of high gain mode)
Short press the LNA ON/OFF button, the "SCAN..." will be displayed on the OLED
screen. It means that the receiver is based on the current wireless environment to
scan all the available channels. Once the scanning is completed, the channel quality
of all available channels will be displayed as stars on the OLED screen. (as depicted
in the diagram) The more the stars, the better the reception.
Place the transmitter and receiver in a higher position to avoid the signal blocking.
