The wireless video data RC control link provides multiple service interfaces, உட்பட 3 ஈதர்நெட் துறைமுகங்கள், 1 RS232 serial port, மற்றும் 1 control serial port.
There is more and more unmanned equipment, and the mutual interference between links is becoming more and more serious. The anti-interference ability of the link is particularly important. For this reason, we specially launched a strong anti-interference video transmission, which supports automatic jumping of 22 அதிர்வெண் புள்ளிகள். frequency supports 15-150 kilometers transmission distance, supports dual network ports 4 தொடர் துறைமுகங்கள் (232, TTL, 485, 422 விருப்ப), 2-way Sbus, supports high and low temperatures -40 க்கு +85 டிகிரி. Support point-to-point, புள்ளி-க்கு-பலபுள்ளி, Mesh ad hoc network. Supports small form factor micro boards.

RJ45 ethernet port
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 பரவும் முறை, 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.

விண்ணப்ப:
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-multipoint star network two-way communication.
In point-to-multipoint 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-multipoint 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. எனவே, 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. எனவே, when the device is used to transmit IP Camera video data, the wireless transmission distance can be improved by setting appropriately reducing the IP Camera video encoding bit rate.
