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.

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.

用于无线视频数据音频RC控制链路的Sbus

下订单时, TX900可以添加到内置的SBU界面.

the sbus pin define in the 15km－150km transceiver D2 interface — SBU PIN在15 km－150km收发器D2接口中定义

D2是一个复合界面, 包括GND, sbus in and sbus out.
在地面遥控侧, 您需要将其连接到TX900的D2 SBU-IN接口.
在空中飞行控制侧, 您需要将其连接到TX900的D2 SBU-OUT接口.

TX900不需要SBU界面, 并且需要外部TTL到SBUS适配器板

题 1: 连续剧 3 – 必须建立 sbus 连接 10 TX900 完成启动序列后的秒数. 除此以外, TX900无法启动且无法配对.

串行 3 是系统调试端口, 复用为透传串口. 系统启动过程中, 如果连续 3 接收数据, 系统启动可能会暂停, 就会出现你提到的问题.
请确保TX900已开机, 启动witin10s时不向D3串口发送数据, 10s后随便发送数据.

题 2: 如果我们使用串行 1 用于小型总线, sbus数据帧在工作过程中损坏.

当您使用串行 1 连接到 sbus 模块, sbus 上的数据量是多少? (例如, sbus的一帧是 25 字节, 客户端在时间内发送了多少帧 1 第二?)
我用的是串口 1 连接到sbus模块进行测试. 每20ms发送一帧Sbus数据就可以了 (相当于发送 50 1秒内的帧数). 我不知道你为什么说有问题.
此外, 当你测试串行时 1, 短距离测试或长距离测试会丢失数据吗?

题 3: 您的TX900远距离无线视频发射器和接收器是否支持Sbus和TTL?

我们可以制作Sbus的D2串口, D1, 和 D3 TTL 或 RS232 串行端口.

我收到的无人机无线视频数据收发器串口是RS232. 我需要 Sbus 和 TTL 用于飞控和相机云台. 我现在该怎么办?

1. 如果可以打开收发器, 并将硬件从RS232更改为TTL, 请检查以下链接.

2. 如果您不想通过拆开收发器外壳来改变硬件, 您还可以在收发器外部添加适配器.

一位客户在发货前没有告诉我们他需要什么样的连接器.
客户必须使用外部转接板来连接飞控和云台相机, 如下图所示.
给后续连接带来很多麻烦. 当您下订单时, 请告诉我们您需要什么样的界面, 例如, TTL (UART) 连接飞控和Sbus 连接云台云台.

无人机RS232改为Sbus和UART遥测的成本?

它是免费的. 下单的时候告诉我需要rs232还是Sbus就可以了.

我的TX-900默认数据串口是UART, 现在我如何将其更改为Sbus以支持我的无人机遥控器?

你需要买一对 (两块) 转换板的. UART 至 Sbus 和 Sbus 至 UART.

当您下订单时, 请尝试告诉我您需要哪些数据串行端口. 我们可以在我们的无人机收发器TX900中安装sbus模块, 如上图所示. 如果您不告诉我们您需要 sbus 接口, 我们将其设为默认的RS232或UART TTL通用数据接口.
如果您的工程师发现仍然需要 sbus 接口, 您将必须使用以下转换模块.

RS232 转 Sbus 转换器模块

如果您在订购 TX900 时没有请求 Sbus 接口, 我们的 TX900 的三个数据端口将是 RS232 或 UART TTL.
是否有RS232数据接口, 您可以使用RS232转Sbus模块并将其连接到TX900外壳来实现此功能.
