HCL536 aircraft transmitter receiver supports 2 operating modes: Access Node or Central Node. It is a web controlled wireless video transmitter and supports up to 16 Access Nodes connected to one Central Node. All nodes share the entire transmission bandwidth (maximum 30 Mbps @ 20 MHz throughput).
The data from the central node to the access node is referred to as downlink, while the data from the access node to the central node is called uplink. The ratio of uplink and downlink data streams can be controlled through the Web UI.
Supported Multiple Network Modes
Point-to-Point Network
Point to Multipoint Network
Relay Network
Mesh Networking
Frequently Asked Questions
Q1. This Ethernet aircraft transmitter receiver support IP camera, what if I want HDMI or SDI video input?
The default video input is IP RJ45 Ethernet port. For cameras with HDMI, SDI, AHD or AV output, we recommend using our mini encoder device to encode the video/audio signal into digital data for transmission. At the receiver end, you can connect directly to your computer or NVR. For HDMI monitor output, our decoder device can convert the digital data back into HDMI video and audio signals.
Q2. For the 800MHz and 1.4G band? Which one would be better?
If your local area has DVB-T or DVB-T2 digital television signal in the 170-860Mhz range, the 1.4G band would be better. Additionally, since GPS antennas on drones point upward and transmitter antennas point downward, the 1.4G frequency has negligible effect on GPS signals.
Q3. Does it support using multiple cameras on the transmitter to only one receiver?
Yes, there are two solutions for multiple cameras:
1. 4 IP cameras -> Net Hub -> Transmitter ↔ Receiver -> Computer Screen
2. 4 IP cameras -> NVR HDMI output -> HDMI encoder IP output -> Transmitter ↔ Receiver -> computer screen.
Q4. Does the transmitter on the air give failsafe command to the flight controller when the connection between air and ground will be lost?
The serial port is transparent and doesn't actively send data to the flight controller. This is controlled by the ground station. You can monitor the link status via LED indicators:
| Link LED |
Wireless link status |
| No light |
This node is not connected with the wireless network |
| Red light |
The wireless link signal is weak |
| Orange light |
The wireless link signal is in middle |
| Green light |
The wireless link signal is strong |
Q5. Can the transmitter and receiver be interchanged for use with change in the setting?
Yes, the difference between transmitter (on drone) and receiver (on ground) is:
1. Device type: transmitter is the access node and receiver is the central node.
2. Rate ratio of the downlink and uplink. Over 30km, the best rate ratio is 4:1 or 3:2.
