XK-F311E Wireless Video and Data Link
Build a video, telemetry and control link around a compact 102 × 55 × 26 mm radio. XK-F311E combines network data, serial data and SBUS control for unmanned-platform projects, with separate air-unit and ground-unit power requirements.
- ≤160 g device weight gives platform builders a defined radio weight for their installation budget.
- 8–30 V DC input, nominal 12 V, supports integration around a selected DC supply.
- Network, UART (TTL/RS232) and SBUS connections carry different project data over the link.
- Point-to-point and point-to-multipoint relay modes allow the unit layout to follow the project.
XK-F311E Wireless Video and Data Link Overview
XK-F311E is a compact wireless video and data link for companies connecting cameras, control equipment and a ground station. Its network and transparent serial-data functions let video traffic and control data travel through the same radio system, while the terminal interfaces determine the connection arrangement.
The listed air and ground radios share a 102 × 55 × 26 mm enclosure and a device-weight rating of ≤160 g. Their electrical loads differ: the air unit is listed at 9 W and the ground unit at 7 W. This separation helps you size the supply at each end rather than treating the pair as one electrical load.
Xingkai checks the requested frequency configuration, terminal interfaces and unit quantities when preparing the model and accessory quotation. The supplied radio units, antennas and cables are identified before the order is confirmed.

Connections and Integration
F311E carries the onboard network-video stream alongside UART TTL/RS232 telemetry and SBUS control. At the ground station, serial or UDP/TCP connections deliver the data to the receiving equipment. Identify each terminal’s electrical level so video transport and the control wiring form one usable installation.
The listed air and ground bandwidths are 10 MHz and 2.5 MHz respectively. Plan the two endpoint roles together, selecting the 1400–1495 MHz or 2400–2483 MHz configuration around the equipment and traffic required in each direction.
Configure the F311E Air and Ground Roles
Provide the platform camera/control connections and the ground receiving equipment as one link plan. Xingkai quotes the selected F311E frequency configuration, air/ground roles, UART level and accessories, with each endpoint’s supply requirements identified separately.
Identify the network camera or encoder, TTL or RS232 telemetry terminals and SBUS requirement. State the desired 1400–1495 MHz or 2400–2483 MHz configuration, traffic in each direction, existing endpoint equipment, actual supplies and required unit quantities.
Xingkai checks the proposed terminals and endpoint arrangement against the listed air 10 MHz and ground 2.5 MHz roles. The quotation identifies the selected frequency configuration, radio roles, UART level and agreed antennas, cables and interface-equipment scope.
Confirm the 8–30 V DC inputs, with 9 W allowed for the air radio and 7 W for the ground radio. Check the 102 × 55 × 26 mm device against the installation space, then agree configuration, accessories, quantities and delivery terms.
Xingkai supplies and ships the agreed F311E endpoint configurations and listed accessories according to the confirmed order.
FAQs
An external network encoder needs its own space, wiring and power alongside the 102 × 55 × 26 mm F311E radio. The air radio’s 9 W entry does not cover the encoder or camera. Send the camera output format and any encoder already selected, plus the remaining mounting space and available power. Mark retained equipment and any encoder/supply items to be quoted separately before choosing the final onboard layout.
No. That entry is the serial-port rate. The separate downlink-throughput entry is 2–15 Mbps at 10 MHz bandwidth. For a camera project, give the encoded stream bitrate and any concurrent data traffic so the proposed radio configuration can be checked against the actual traffic, rather than using the serial value as a video-capacity figure.
The ≤160 g entry is a device-weight rating. It does not specify the complete assembly carried by your platform. Include antenna, cable and mounting requirements when requesting the configuration; confirm those components separately before fixing the installation weight budget.
Identify the role first. F311E lists air 10 MHz/9 W and ground 2.5 MHz/7 W entries, so a spare labelled only with the family name is not a complete role specification. Send the retained units’ full versions, selected frequency and settings, and show whether the new unit replaces an endpoint or adds one to a multipoint arrangement. Request that exact role and its connecting accessories in the quotation.
F311E lists 2.5 dBi for the air side and 7 dBi for the ground side. Describe the moving platform’s antenna location separately from the ground position and viewing/coverage direction. Identify any existing antennas and their supported frequency before reusing them with the selected 1.4 or 2.4 GHz configuration. Have the intended antennas and leads identified for each endpoint rather than copying one end’s parts to the other.
