===== USB2AX: Getting started =====

==== Installation ====

=== Linux === 
No driver needed, just plug the USB2AX in a USB port and the Status LED should light up very briefly in red then in solid green.\\
The USB2AX should appear as ///dev/ttyACM*//.

The user must be part of the **dialout** group to have access to the serial port!

If the Status LED stays red and the device does not appear in ///dev//, check that __USB Modem (CDC ACM) support__ is enabled in the kernel. All recent desktop distributions have it enabled by default.

If you plan on using Robotis' Dynamixel SDk for Linux, have a look [[product:usb2ax:faq#qdynamixel_sdkhow_do_i_use_it_with_the_usb2ax|here]]!


=== MacOS ===
Same as for Linux, except the USB2AX will appear as /dev/tty.usbmodem*****.

=== Windows XP, Vista, 7, 8, 8.1 ===


Before the first use, you will need to install the [[https://raw.github.com/Xevel/usb2ax/master/firmware/lufa_usb2ax/USB2AX.inf|USB2AX.inf driver file]] (//Right click > Save as...// to download it).

For Windows 8 and 8.1, you need to follow the procedure to disable driver signature enforcement before you can install the driver ([[http://www.howtogeek.com/167723/how-to-disable-driver-signature-verification-on-64-bit-windows-8.1-so-that-you-can-install-unsigned-drivers/|ENG]] / [[http://wiki.cybedroid.net/index.php?title=D%C3%A9sactivation_de_signature_de_pilotes|FR]]).


The installation is similar to the one for [[http://arduino.cc/en/Guide/Windows#toc4|the Arduino Uno]] ([[http://arduino.cc/en/Guide/UnoDriversWindowsXP|step-by-step under XP]]).

  - Plug the USB2AX into a USB port. The Status LED should light up red and Windows might start looking for a driver [Vista, 7]. You can cancel the search, the driver is not on Microsoft's servers.
  - Open the Device Manager. (//Start Menu > Control panel > System and Security > System > Device Manager//).
  - In the //Ports (COM & LPT)// section, you should see a "USB2AX" device with a little exclamation mark. //Right click > Update Driver Software > Browse my computer for Driver software//
  - Here, navigate to and select the //USB2AX.inf// driver file.
  - Windows will do the rest. If it raises concerns because the driver is not signed, continue.

Once installation is complete, the Status LED should turn solid green.

==== Example of use ====


//This part explains how to connect the USB2AX and make a Dynamixel servo  move using RoboPlus Dynamixel Manager, on Windows.//

{{product:usb2ax:usb2axv3.1_connected_s.jpg}}

=== 1) Gather the required parts ===

  * USB2AX
  * a compatible Dynamixel servo (AX-12A for example)
  * Dynamixel cable(s)
  * a way to power the servo (see [[faq#Q: How to power the servos?]])
  * a computer running Windows

=== 2) Installation ===

[[#Windows XP, Vista, 7|Install the driver of the USB2AX]], and the latest version of [[http://support.robotis.com/en/software/roboplus_main.htm|RoboPlus]].

=== 3) Make the servo move! ===

  * Plug the 3-wire dynamixel cable between the USB2AX and the first servo, and wire-up all other servos.
  * Plug the USB2AX in the USB port, it should appear as a Virtual COM port.
  * Apply power to the servos.
  * Run RoboPlus Dynamixel Wizard, open the corresponding COM port and run "Search" (DXL1.0).
  * You should be able to make the servos move by changing the "Target Position" value.
