Product Installation

Installation of Transmitter

1. Install the antennas to the antenna connectors , and arrange them to be fan-shaped.(As shown in the figure below)
   

2. Please install the transmitter on the 4K camera through the V-mount plate on its back, and use the V-mount battery to power up the transmitter and the camera simultaneously. (As shown in the figure below)

3. Please connect the transmitter properly to the camera using a HDMI/SDI cable. (Please note that “HDMI” or “SDI” will appear on the OLED display when the corrsponding cable is connected.)
   

Installation of Receiver

1. Install the antennas to the antenna connectors, and arrange them to be fan-shaped. (As shown in the figure below)
   

2. Please place the receiver at a height of around 1.5 to 2 meters above the ground. The receiver can be installed through the 3/8″ screw hole in the bottom.

3. Please connect the receiver to a monitor with a HDMI/SDI cable. (Please note that “HDMI” or “SDI” will appear on the OLED display when the corrsponding cable is connected.)
   

4. The receiver can be powered by the battery mounted on the V-mount plate, or connected to the XLR port via a power adapter. If both are connected , the battery will be used in priority, and will automatically switch to the power adapter when the battery runs out.

Tally

Tally

• First, plug the Tally indicator into the transmitter’s Tally output , and connect the switch console to the receiver’s Tally input. Then, the transmitter’s Tally indicator can be controlled by the switch console. The transmitter’s Tally indicator is turned on when the receiver is triggered by low level.
• The Tally port is 3.5 mm phone jack.

Tally output pinout

Tally input pinout

RS232/RS422 transparent transmission

RS232&422 port is RJ45 connector, baud rate can be modified through the display menu UART-Baudrate. The pinout is shown as below:

RTSP Streaming

Please select “Video-RTSP”from the sub-menu to enable the RTSP function. After the setting is completed, please connect the LAN port of the transmitter or receiver to a PC or other device.

Take the VLC application as an example. After opening the VLC application, please select “Open Network Stream” and fill in “rtsp:// IP address of the corresponding transmitter encoding board: 10000/live” in the address field, then click “Play” to start streaming.

Notes:

• The IP address is on the label on the back of the device.
• The transmitter must be connected to the video source, and the IP address of the terminal streaming device (such as a computer) must be in the same network segment as the IP of the encoding board in the transmitter. Otherwise, the RTSP streaming mode will not work.
  
  

Firmware Upgrade

Firmware upgrade through USB port

Please copy the latest firmware to the root directory of a USB disk(FAT-32 format) and connect it to the transmitter and receiver respectively, and select “Systemupgrade-yes” in the menu bar on the display. The display will show “Pls Wait…”, which means the upgrade is in progress. Once the upgrade is completed, the system will restart automatically.

Note: The firmware for the transmitter is different from that of the receiver. The upgrade process may take approximately one minute.

Troubleshooting

1. HDMI input matches HDMI/SDI output; SDI input matches HDMI/SDI output.
   The SDI and HDMI output cannot be supported simultaneously by the receiver.
   The corresponding input and output operations can be selected based on the display instructions. For details, please refer to the button operation.

2. Please connect the transmitter to the video source, and the receiver to the monitor, then power them up.

3. If the connection fails, please restart the transmitter and receiver. If the connection still fails, please refer to the button operation instructions to do re-pairing.

4. If no video source is displayed on the monitor after switching the video source resolution, please re-plug the HDMI cable of the transmitter or receiver. If there is still no signal after unplugging and plugging the HDMI cable, please restart the transmitter and receiver.

5. If the connection cannot be established after switching the channel, please restart the transmitter and receiver.

6. If the image is interfered, please try to switch the channel. For channel switching, please refer to the channel switching instructions.

7. Never power up the product without the original antennas and power adapter.

8. During use, the surrounding environment might affect wireless transmission quality. These situations are below:
   a: Walls, large metal plates, and appliances may disrupt wireless transmission.
   b: When using the equipment in crowded environment, please place the transmitter and receiver at the height of around 1.5-2 meters above the ground.
   c: If 5GHz wireless devices are used nearby, these may also increase interference, which can be solved by switching to a different channel.
   d: To achieve best wireless transmission performance, please arrange the antennas to be fan-shaped at the transmitter and receiver side with a clear line of sight.
