XK-F403E Wireless Video and Data Link
XK-F403E combines network video, telemetry and remote-control data in one wireless radio system. Xingkai specifies the radio configuration, air and ground quantities and accessories for the terminal equipment and link layout your project requires.
- Ethernet traffic, UART telemetry and SBUS control share the wireless link, with TTL, RS232 or RS485 selected to suit the serial terminals.
- Point-to-point and point-to-multipoint relay arrangements let you specify the endpoint roles for the required platform and ground equipment.
- A 140 × 114 × 29 mm enclosure and device weight of ≤470 g define the radio installation footprint and equipment-weight budget.
- The reference RF-output entry is 2 × 33 dBm, adjustable, giving you a configuration value to assess together with antennas, electrical load and deployment conditions.
XK-F403E Wireless Video and Data Link Overview
XK-F403E carries network traffic, flight-control data, camera-control data and remote-control data through one wireless link. Transparent serial and SBUS transmission support the control paths alongside IP video, so the radio configuration can follow the terminals selected for your project.
The radio is 140 × 114 × 29 mm with device weight of ≤470 g. Its listed RF-output entry is 2 × 33 dBm, adjustable, while electrical consumption is ≤20 W at the stated 33 dBm condition. These are different measurements: plan the electrical load separately from RF output, and include the antennas, cables and mounting components in the installation budget.
Xingkai checks the full model configuration and terminal arrangement, then quotes the required radio units and accessories. Confirm the exact supplied electrical and frequency configuration, quantities and delivery terms before ordering; similar model names or range suffixes are not a basis for assuming interchangeable equipment.

Connections and Integration
Use F403E’s Ethernet path for network video, UART TTL/RS232/RS485 for the selected telemetry or payload terminal, and SBUS for remote control. The ground station exchanges data through serial or UDP/TCP connections. Choosing the serial electrical form makes the required terminal wiring explicit.
The selected technical-table configuration accepts 12–30 V DC, nominal 22 V, with ≤20 W consumption at 33 dBm. Budget that electrical load alongside the connected equipment; it is separate from the listed adjustable 2 × 33 dBm RF-output configuration.
Specify the F403E Electrical and Radio Configuration
The quotation identifies the supplied F403E electrical configuration, selected 600 MHz or 1.4 GHz band, bandwidth and terminal connections. Provide both endpoint installations so the radio quantities, RF/antenna arrangement and accessories follow the equipment you need to connect.
List the network-video source, UART terminal models and TTL, RS232 or RS485 requirement, plus any SBUS path. Give the actual supply range at each end, requested band/bandwidth, endpoint roles, concurrent traffic and quantities.
Xingkai checks the terminal plan against the selected 12–30 V DC, nominal 22 V configuration. The quote identifies the supplied radio version, band, 3/5/10/20 MHz bandwidth, electrical connections and agreed RF/antenna and cable scope.
Agree the actual supplied RF configuration and required antenna connections; the reference lists adjustable 2 × 33 dBm, with electrical consumption ≤20 W at 33 dBm. Confirm both supplies, the 140 × 114 × 29 mm installation, accessories, quantities and delivery terms.
Xingkai supplies and ships the confirmed F403E configuration, endpoint quantities and listed accessories according to the agreed order.
FAQs
The selected F403E technical-table configuration lists 12–30 V DC, nominal 22 V. Compare the supply’s actual operating range with those limits, including its highest output, rather than checking only the nominal 24 V label. Send those supply details and the other loads at that endpoint. If the quoted radio version has different requirements, agree its power arrangement before retaining a supply or selecting an external converter.
Identify each retained unit’s full version, selected 600 MHz or 1.4 GHz band, bandwidth and settings. Show which endpoints must send video together and which UART terminals use TTL, RS232 or RS485. Request the proposed multipoint arrangement, added-unit role and changed terminal/RF connecting items against that retained system. The nodes share operating bandwidth in one direction, so an extra radio does not establish an independent full-rate allocation.
Keep the listed 2 × 33 dBm RF configuration separate from electrical consumption and application capacity. Do not turn it into a single 66 dBm setting or two independent video-link allowances. Describe the antenna/RF connections, selected operating mode and traffic your installation requires, then have that supplied arrangement identified in the quotation. Compare the complete proposed installation and its power needs, rather than choosing from an added power number or a distance label.
XK-F403E carries IP video through a network connection. Provide the camera model and output type so Xingkai can check the video-to-network and encoding arrangement. Any encoder or interface equipment required between the camera and radio should be identified separately in the configuration and supply list. Do not assume that the camera’s HDMI connector is a direct radio input.
Start with the F403E’s ≤470 g device entry, then add the actual air-side antennas, RF leads, data/power cables, mounting parts and any encoder. Identify which existing components will remain and which new items are quoted. Compare that complete onboard assembly with the alternative, keeping ground equipment separate. The RF-output notation does not define an antenna package or its installed weight.
