Various Cabling Methods
Caution
The Dynamixel-X Series cable assembly through hollow case. Organize the entangled cable before assembling the back case.
Do not assemble the back case with entangled cable. The entangled cable can be squashed by the case and cause communication error. If you use two cables through the hollow case, the cables will be damaged. Use only one cable through the hollow case.
The Dynamixel-X Series adopted a new gold-plated JST connector for secure and reliable communication. The connector used for previous Dynamixel is Molex.
To control Dynamixel-X Series actuators via OpenCM or USB2Dynamixel, please use the JST-Molex Convertible Cable enclosed in the package.
However, the Molex-JST convertible cable is NOT included in the XL430 model. Please purchase a convertible cable when using a controller and interface that supports the JST connector.

Dynamixel SDK:
Provides various control environment just like Dynamixel
Dynamixel SDK is a software development kit that provides Dynamixel control functions using packet communication. The API of Dynamixel SDK is designed for Dynamixel actuators and Dynamixel-based platforms. You need to be familiar with C/C++ programming language for right use of the software. This e-Manual provides comprehensive information on ROBOTIS products and applications.
Supported Protocols
To control Dynamixel, communication should be established according to the protocol of Dynamixel. There are versions 1.0 and 2.0 of the Dynamixel protocol. The Dynamixel SDK supports both, and the user can use both protocols simultaneously using the Dynamixel SDK. Refer to the following manuals for details on the protocols.
- Dynamixel Protocol 1.0
- Dynamixel Protocol 2.0 (Recommended protocoltype)
Supported Devices
The Dynamixel SDK can be used on PCs such as desktops or laptops, as well as on tablets, and also on SBCs like Raspberry Pi and UpBoards. In addition, it can be used with embedded boards that support the Arduino IDE. Dynamixel uses TTL and RS485 communication. In order to use computer and Dynamixel, we recommend USB2Dynamixel or U2D2 as interface device.
Supported Operating Systems
The Dynamixel SDK supports all three operating systems: Windows, Linux, and MacOS.
Supported Languages
The Dynamixel SDK supports various programming languages: C, C++, C#, Python, Java, MATLAB and LabVIEW.
In addition, Dynamixel SDK supports ROS, so it can be used as ROS library using C++ or Python modules.
- C: *Dynamic library and source code of this library and examples
- C#, Java, MATLAB, LabVIEW: Support based on dynamic library using C language
- C++: *Dynamic library and source code of this library and examples
- Python: Python module and examples
- ROS: ROS library using C++ and Python modules
(* Dynamic library (*.dll, *.so, and *.dylib files) / .dll: dynamic-link library on Windows / .so: shared object on Linux / .dylib: dynamic library on macOS)
