Question 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? (For example, one frame of sbus is 25 bytes, how many frames are sent by the client within 1 second?) 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. In addition, when you test serial 1, do you lose data in a short-distance test or a long-distance test?

Question 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, please check the below link. https://ivcan.com/change-rs232-to-ttl-of-wireless-video-data-link-modem/ 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, for example, 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.

Q: Question 1: The serial 3 - sbus connection must be established 10 seconds after TX900 finishes the booting sequence. Otherwise, TX900 will not be booted and those can not be paired.

serial 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.

下訂單時, TX900可新增內建Sbus接口.

D2是複合介面, 包括接地, Sbus in and Sbus out.
地面遙控側, 您需要將其連接到TX900的D2 sbus-in接口.
On the air flight control side, 您需要將其連接到TX900的D2 sbus-out接口.

TX900之前不需要Sbus接口, 並且需要一個外部 TTL 至 Sbus 轉接板

問題 1: 連續劇 3 – 必須建立 sbus 連接 10 TX900 完成啟動序列後的秒數. 否則, TX900無法啟動且無法配對.

連續劇 3 是系統調試埠, 復用為透傳串口. 系統啟動過程中, 如果連續 3 接收資料, the system startup may be suspended, and the problem you mentioned will appear.
請確保TX900已開機, 啟動witin10s時不向D3串口發送數據, 10s後隨便發送數據.

問題 2: 如果我們使用串行 1 用於小型匯流排, the sbus data frame is corrupted during working.

當您使用串行 1 連接到 sbus 模組, what is the amount of data on the sbus? (例如, sbus的一幀是 25 位元組, 客戶端在時間內發送了多少幀 1 第二?)
我用的是串口 1 to connect to the sbus module for testing. 每20ms發送一幀Sbus資料就可以了 (相當於發送 50 1秒內的幀數). 我不知道你為什麼說有問題.
另外, 當你測試串行時 1, 短距離測試或長距離測試會遺失資料嗎?

問題 3: 您的TX900遠距離無線視訊發射器和接收器支援Sbus和TTL嗎?

We-can-make-the-D2-serial-port-for-Sbus-D1-and-D3-serial-ports-for-TTL-or-RS232

我們可以製作Sbus的D2串口, D1, 和 D3 TTL 或 RS232 串列埠.

我收到的無人機無線視訊資料收發器串列埠是RS232. 我需要 Sbus 和 TTL 用於飛控和相機雲台. 我現在該怎麼辦?

1. 如果可以開啟收發器, 並將硬體從RS232更改為TTL, 請檢查以下連結.

2. 如果您不想透過拆開收發器外殼來改變硬件, 您也可以在收發器外部新增適配器.

它是免費的. 下單的時候告訴我需要rs232還是Sbus就可以了.

My TX-900 default data serial port is UART, 現在我如何將其更改為Sbus以支援我的無人機遙控器?

你需要買一對 (兩塊) 轉換板的. UART 至 Sbus 和 Sbus 至 UART.

如果您在訂購 TX900 時沒有請求 Sbus 接口, 我們的 TX900 的三個資料連接埠將是 RS232 或 UART TTL.
是否有RS232資料接口, 您可以使用RS232轉Sbus模組並將其連接到TX900外殼來實現此功能.
