介绍
The wireless video data RC control link realizes long-range two-way wireless video, 音频, and data transmission, and the longest air-to-ground transmission distance can reach about 22km.
The wireless video data RC control link provides multiple service interfaces, 包括 3 Ethernet ports, 1 RS232 serial port, 和 1 control serial port.

RJ45以太网端口
The three Ethernet ports are internally bridging (with the same IP address), and the wireless network port is in the transparent transmission mode of IP data.
For applications that require HDMI/SDI/AV/AHD video 传送, the video transmitter must add H265/H264 encoding board, which can be directly connected to the 4Pin Ethernet port for matching use.
RS232 data serial port
1 channel RS232 serial port for transparent data transmission, 3PIN PH1.25mm spacing socket, the signal of each PIN pin is shown in the figure below. The default baud rate is 115200, which can be changed through the Web UI or the AT command of the control serial port.
Control serial port
Control serial port (C-TTL), 3PIN PH1.25mm pitch socket, see the above picture for the signal of each PIN pin. The upper computer can configure and view the parameters and working status of the wireless link device through the AT command of the control serial port.

应用:
The use of wireless video data RC control link can realize long-distance two-way wireless data communication, point-to-point two-way communication, and point-to-multi-point star network two-way communication.
In point-to-multi-point communication, if two access nodes need to communicate through the central node, each node is in the same wireless local area network, and all access nodes and the central node share the wireless working bandwidth, and the device will automatically average Assign system speed. The data transmission from the central node to the access node is called the downlink, and the data transmission from the access node to the central node is called the uplink.
In point-to-point or point-to-multi-point communication, the downlink and uplink share the wireless working bandwidth. When the device is shipped, the default setting is the ratio of uplink rate to downlink rate = 4:1. 因此, if the device is used to transmit IP Camera video data, the IP camera should be connected to the access node.
The device will automatically and dynamically adjust the wireless transmission rate according to the carried business data stream. When the amount of carried business data is smaller, the transmission distance will be farther under the same conditions. 因此, when the device is used to transmit IP Camera video data, the wireless transmission distance can be improved by appropriately reducing the IP Camera video encoding bit rate.

常问问题
Q: Do you have equipment that supports 5km ground transmission between densely populated buildings?
一个: All transmission distances mentioned in our price list or website refer to the transmission distance from the drone in the visual range to the ground receiver.
Q2: How does the dual frequency of this model work? When one frequency is interfered with, will it automatically jump to another frequency?
A2: Vcan1806 supports two frequencies working simultaneously: 1.4G (1420～1530MHz) and 600Mhz (566~678MHz).
When 1.4GHz is interfered, 600MHz can still allow the device to work normally. When 600MHz is interfered, 1.4GHz will also allow the device to maintain good communication.
Just like the drone in the air and the ground workstation are connected by two links at the same time. If one link is interfered, the other link can also keep the two devices unobstructed between our wireless video data transceiver.
The original FHSS frequency hopping function is also supported. If there is interference at 1.4GHz, our device will automatically search between 1420-1530Mhz and automatically switch to the frequency with the strongest signal. 例如, if there is interference at 1420Mhz, it may automatically switch to 1500Mhz, which is the frequency with the least interference.
Q3: What is the maximum transmission rate supported by this bidirectional dual-band frequencies of drone wireless link?
A3: Support 100Mbps.
第四季度: What is the ID and password for accessing the web UI page management?
A4: Both the 用户名 和 密码 for accessing the web UI management interface are 行政 默认情况下.
