Product overview
The Xingkai XK-F415E provides a wireless connection for carrying camera imagery alongside aircraft and payload control information. It can transmit encoded HD camera network traffic, flight-control data, gimbal commands and remote-controller data simultaneously. Transparent serial and SBUS transmission support integration with these control paths, while the ground end exchanges data with a ground station through serial connections or UDP/TCP network ports. Point-to-point, point-to-multipoint and relay operation give the equipment several network arrangements, and users can set the channel encryption key.
The hardware comprises airborne and ground endpoints with an equipment size of 125 × 95 × 42mm and weight of no more than 650g. Its antenna configuration distinguishes the endpoints: two 30cm foldable rubber antennas for the airborne end and two 120cm fiberglass omnidirectional antennas for the ground end. Main and secondary antenna connections accompany a J30 connector carrying Ethernet, three UART channels, SBUS and DC power. Two additional Ethernet ports support up to three cameras airborne and three monitoring computers on the ground.
Integration requires a DC20–28V supply, with DC24V specified as the standard input and consumption limited to 65W. The operating-frequency specification is 1420–1530MHz, with optional 600MHz or 1.4GHz band configurations also offered. Bandwidth settings are 3, 5, 10 and 20MHz. At 20MHz, the central and subordinate nodes share at least 100Mbps of bandwidth in one direction; this is a shared network resource. Transmission latency is specified at no more than 15ms. Operating temperatures span −30°C to 60°C, and maintenance includes local, remote and OTA upgrades.
