عند تقديم الطلب, يمكن إضافة TX900 إلى واجهة Sbus المدمجة.
D2 is a composite interface, including GND, Sbus in and Sbus out.
On the ground remote control side, you need to connect it to the D2 sbus-in interface of TX900.
On the air flight control side, you need to connect it to the D2 sbus-out interface of TX900.
TX900 did not require a Sbus interface before, and an external TTL to Sbus adapter board was required
جدول المحتويات
سؤال 1: The serial 3 – sbus connection must be established 10 seconds after TX900 finishes the booting sequence. خلاف ذلك, TX900 will not be booted and those can not be paired.
مسلسل 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.
سؤال 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? (على سبيل المثال, one frame of sbus is 25 بايت, how many frames are sent by the client within 1 ثانية?)
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.
فضلاً عن ذلك, when you test serial 1, do you lose data in a short-distance test or a long-distance test?
سؤال 3: Does your TX900 long-range wireless video transmitter and receiver support Sbus and TTL?
We can make the D2 serial port for Sbus, د1, 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, يرجى التحقق من الرابط أدناه.

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. عند تقديم الطلب, please tell us what kind of interface you need, على سبيل المثال, 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.

عند تقديم الطلب, please try to tell me which data serial ports you need. We can install the sbus module in our drone transceiver TX900, as shown in the picture above. In case you don’t tell us that you need a sbus interface, we will make it a default RS232 or UART TTL universal data interface.
If your engineer finds that there is still a need for an sbus interface, you will have to use the following conversion module.
RS232 to Sbus Converter Module
If you did not request a Sbus interface when you ordered the TX900, the three data ports of our TX900 will be RS232 or UART TTL.
If there is an RS232 data interface, you can use the RS232 to Sbus module and connect it to the TX900 shell to achieve this function.
