Sbus for Wireless Video Data Audio RC control Link TX900
목차
문제 1: The serial 3 – sbus connection must be established 10 seconds after TX900 finishes the booting sequence. 그렇지 않으면, TX900 will not be booted and those can not be paired.
연속물 3 is the system debugging port, which is multiplexed for the transparent transmission serial port. During the system startup process, if serial 3 receives data, the system startup may be suspended, and the problem you mentioned will appear.
Please ensure that the TX900 is powered on, do not send data to the D3 serial port while starting witin10s, and send the data casually after 10s.
문제 2: If we use serial 1 for sbus, the sbus data frame is corrupted during working.
When you use serial 1 to connect to the sbus module, what is the amount of data on the sbus? (예를 들면, one frame of sbus is 25 바이트, how many frames are sent by the client within 1 초?)
I use serial 1 to connect to the sbus module for testing. It is okay to send a frame of Sbus data every 20ms (equivalent to sending 50 frames in 1s). I don’t know why you said there is a problem.
게다가, when you test serial 1, do you lose data in a short-distance test or a long-distance test?
문제 3: Does your TX900 long-range wireless video transmitter and receiver support Sbus and TTL?
We can make the D2 serial port for Sbus, D1, and D3 serial ports for TTL or RS232.
The serial port for the drone wireless video data transceiver I received is RS232. I need Sbus and TTL for the flight controller and camera gimbal. What should I do now?
1. If you can open the transceiver, and change the hardware from RS232 to TTL, 아래 링크를 확인해주세요.

2. If you don’t want to change the hardware by disassembling the shell of the transceiver, you can also add an adapter outside the transceiver.
The following picture is the adapter board of rs232 to S-Bus.
One customer didn’t tell us what kind of connector he needed before delivery.
The customer had to use an external adapter board to connect the flight control and the PTZ camera, as shown in the picture below.
It brings a lot of trouble to the follow-up connection. When you place an order, please tell us what kind of interface you need, 예를 들면, TTL (UART) to connect to the flight control and Sbus to connect the PTZ camera gimbal.
Cost of changing RS232 to Sbus and UART telemetry for UAV?
It is free. Just tell me whether you need rs232 or Sbus when you place an order.
My TX-900 default data serial port is UART, Now how can I change it to Sbus to support my drone remote controller?
You need to buy one pair (two pieces) of the converter board. UART to Sbus and Sbus to UART.
