About
Product model and standard
Hollyland Cosmo 400 Long Range Wireless HDMI/SDI Transmission Suite utilizes
today’s most advanced wireless video transmission technology, which can
realize the broadcast-class and uncompressed 3G SDI/HDMI HD video signal
transmitted with no compression and zero delays. The suite includes one
transmitter and one receive, where the transmitter provides a 3G/HD SDI input
and an HDMI input, and the receiver also provides a 3G/HD SDI output and an
HDMI output. The wireless HD suite has 2 stick antennas in the transmitter
side, and 5 internal antennas on the receiver side, and it can work in a
5.1-5.9GHz frequency band and be flexibly software configured to licensed or
ISM band of global different regions, as well as the side panel of both
transmitter and receiver has been installed a frequenc y select knob, which
provides maximum 10 workable frequency channels, and supports maximum 4 sets
working simultaneously. The wireless suite can accept a wide range DC power
input, which is suitable for many kinds of camera battery models. The suite
also can sustain t8 kV ESD (HBM, c- ontact discharge), the industry-class
metal case, and professional heat d- esign would guarantee the most robust
reliability.

Installation details and cautions
Transmitter side
- Install 2 Omni-directional and high efficiency antennas to transmitter’s RP-SMA female antenna connectors.
- There is one1/4-20 screw in transmitter metal case, which are located on the bottom of case. So the user can utilize a 1/4 screw to ISO518 hot-shoe converter fix the transmitter into camera.
- Install battery into battery buckle if your product model includes battery buckle options; please note the battery model must match the battery buckle type.
- The user can also utilize a subsidiary LEMO 4 pin-male to D-type receptacle power cable to get power input from an outside power source.
- All TX installation guidelines see below figure.
Receiver side
- There is one 1/4-20 screw nut in the bottom side of receiver. The user can utilize a 7″ articulating arm and crab clam to install the receiver on one tripod.
- Install battery into battery buckle if your product model includes the option of battery buckles; please note the battery model must match the battery buckle type.
- The user can also utilize a subsidiary LEMO 4 pin-male to D-type receptacle power cable to get power input from an outside power source.
- All RX installation guidelines see below figure
- Ensure the frequency knobs of the transmitter and receiver are set with the same number, and this will make sure the transmitter and receiver work with same RF frequency.
- If the camera is on and video input is OK, TX side ‘video’ indicator will ight
- Before RX finished wireless link with TX, 4 RSS indicators and ‘Video’ indicators are off when wireless link is OK, RSSI indicators will light first, and ‘RSS’ will indicate the received RF signal strength. If the receiver d detects wireless video normal internally from air interface, Video indicator will light. Before that, if SDI or HDMI video out port of the receiver has HD monitor connected, it will display an OSD of ‘Link Connecting..like below picture.
- The system will spend 20-30 seconds on constructing the link, and real link period will depend on the current wireless channel condition. When wireless link is set up, “RSSI” light willight and indicate current received wireless signal strength, as well Video” indicators willight, and then connected HD monitor will display the video and audio accordingly.
Typical connection instruction
Connect camera SDI or HDMI output to transmitter SDI or HDMI input port, and
the transmitter can fixed in hot-shoe port of the camera. Connect HDMI or SDI
output port of the receiver to SDI or HDMI input port of the HD monitor. Make
sure all antennas and batteries are equipped normally. See below diagram.
Getting started
After finishing all steps above, system is workable, follow below steps.
- Ensure the video source output of the camera is OK, and the HD monitor is power on and switched to connected video input port.
- Ensure all input, output SDI or HDMI cables are connected.
- Ensure 2 TX antennas are installed, and it is better to keep TX 2 antennas with orthogonal angle each other for best RF perfomance. Like below figure.
- Ensure both the transmitter and receiver installed the battery or DC input port connected to outside power source. Then tum power switch of transmitter and receiver to ‘ON’ respectively, then ‘Power indicator will light.
Operation instruction
Input video port selection of transmitter
The transmitter has a 3G SDI video input port and a HDMI video input port, and
the system will detect valid video source automatically of SDI and HDMIport,
and then switch it as main video input channel. If both SDI and HDMI have
valid video input, the system will take SDI input as priority.
RSSI indicators
The receiver will calculate received RF signal strength intermally and 5
“RSSI” LEDs will be used to indicate wireless signal power and quality. The
user can observe the RSSI LED status to know if the current wireless link is
reliable or not. From 1 to 5 lit LEDs show RSSI from Min to Max. 
Frequency selection and configuration
The wireless suite can work in 5.1-5.9GHz frequency band and be flexibly
software configured to licensed or ISM band of global diferent regions, as
well as the side panel of both transmitter and receiver has been installed a
frequency select knob, which provide maximum 10 workable frequency channels,
and support maximum 4 sets working simultaneously. See below frequency knob
figure.
Storage conditions
Products storage temperature should be -20°C-60°C. For long time storage
requirement, please use original carbon boxes, and avoid from high humid, acid
base or dusty place.
Maintenance
Warning: To ensure your safety, place choose original adapters. And provide
stable AC input according to this manual.
Trouble shooting
Normal problems
-
No output on display
Check TX and RX power first, and see if TX or RX battery is existed, then check if TX antenna and RX antenna installed right. After that, check Video indicator, if TX Video’ indicator is not light, then check SDI or HDMI cable is plugged in and video source is ready please. Finally may check input video format is compatible with this product specs. -
Poor output video quality
Check if SDIl or HDMI input or output cable is plugged well, then check how many receiver side ‘RSS” LEDs is lit, there should be 2-3 RSSI LED lit if the user want to get better video quality; if there is only 1 RSSI LED or no LED lit, that means the received wireless signal is weak, and should decrease the transmission distance or try to change to other frequency channels in case
some exist interference.
