Baguhin ang RS232 TTL D2 sa SBus para sa flight control sa wireless video data link transmiter-receiver
A customer asked us to change the D2 data interface to SBus before shipment. So that he can directly link his flight control equipment after receiving the goods.
Our wireless video data link has three data interfaces, D1, D2, and D3, as long as the customer requires, we can change D2 to support SBus or RS485 interface. We can add an RS232 TTL converter SBus module to the inside of the transceiver box. This video is to demonstrate and test whether the SBus modification is successful.
Here we receive the UART data sent by the computer through a UART-to-SBus module, and then through this UART-to-SBus module, simulate receiving the SBus signal from the drone operating joystick. And send it to our wireless video data link receiver, D2 interface, which has been modified to SBus in, D2 ngayon ay maaaring makatanggap ng data ng SBus sa.
Sa kabilang panig, Nakakonekta din kami ng isang wireless video data link transmiter, na kung saan ay isang aparato na konektado sa drone, ito ay magpapadala ng natanggap na signal ng SBus sa flight control device ng drone sa pamamagitan ng D2 data interface. Ngayon ito ay SBus out. Wala kaming mga drone at flight control equipment dito upang gayahin ang proseso ng pagtanggap ng SBus. Sa pamamagitan ng dalawang modyul, ang natanggap na signal ng SBus ay na convert sa UART at ipinadala sa computer.
Ipinapakita ng screen ng computer na natanggap nito ang data ng SBus, na simulates ang buong proseso ng pagpapadala at pagtanggap ng SBus sa pamamagitan ng aming wireless video data link. Kung ang customer ay kumonekta sa kanyang flight control equipment at drone sa SBus out dito, he will receive the SBus signal from a far away distance like a computer, and then he can control the drone by his operating joystick, even in another test video over 110km long-range video data test.
Why do we use D2 instead of D3 to change to the SBus interface? Because D3 is a multi-purpose interface, in addition to the common RS232 TTL data function, it is also a special interface for UART AT commands. The web UI can do some common configurations. Engineers often use UART commands to query and modify parameters through the D3 interface. So we can use D2 to modify it to SBus or RS485 interface.
