1 Tutorial
This guide is written for first-time Dynamixel PRO users, but, familiar with C and C++
programming languages.
1.1 Roboplus
1.1.1 Preparation
i. RoboPlus installation (Windows only)
- RoboPlus is a software package that allows you to easily control and program all
ROBOTIS products.
- This guide contains information regarding the use of RoboPlus’s Dynamixel
Wizard to test Dynamixel PRO.
- You may download the most current version of RoboPlus at
http://www.robotis.com/xe/download.
ii. Wiring of Dynamixel PRO 54 series
- To operate a Dynamixel PRO, at least, a USB-to-Dynamixel dongle and 24V
power supply (for high-power operations) or ROBOTIS’ conventional 12V SMPS
(for low-power operations) are required.
- Dynamixel PRO 54 series can be powered via external power cable or 4-pin cable;
however, it is recommended to use an external power supply (via power cable) for
better stability.
- As illustrated below, use a 4-pin cable to connect the USB-to-Dynamixel dongle
and Dynamixel PRO.
- Connect one end of the power cable to Dynamixel PRO; the other end to the
power supply.

Page 6 / 139
- Please note the schematic below.
- Dynamixel PROs can be connected in series (daisy chain) with the 4-pin cables for
communications (and low-power operations). However, power (high-power
operations) must be supplied in parallel (individually).
iii. Wiring of Dynamixel PRO 42 series
- Similar to the 54 series, the 42 series requires a 24V power supply.
- Dynamixel PRO 42 series can be powered by the 4-pin cable (low-power
operations). Connecting via SMPS-to-Dynamixel is also allowed.
- A USB-to-Dynamixel dongle connects to SMPS-to-Dynamixel; then SMPS-to-
Dynamixel to Dynamixel PRO(s).
iv. Wiring of Dynamixel PRO 54 & 42 series
- First, connect an USB-to-Dynamixel dongle and Dynamixel PRO via 4-pin cable.
- Second, connect a dedicated power supply to Dynamixel PRO via power cable.
For multiple Dynamixel PROs they can be connected in series, for
communications (daisy chain) and low-power operations, and parallel
(individually), for high-power operations, as illustrated below.

- Please note the schematic below.
v. USB-to-Dynamixel dongle (RS485 setting)
- Dynamixel PRO communicates via RS485.
- Set the switch on the left hand side of the USB-to-Dynamixel dongle to RS485
(#2).
vi. COM Port Latency Time setting
- To control Dynamixel PRO using a USB-to-Dynamixel dongle, it is recommended
to modify the Latency Time of the Port. Please refer to the images below to adjust
the Latency Time.
- Under Windows Device Manager à Port à USB Serial Port (right mouse
click)à properties à Port Setting -> Advanced à Latency Timer (msec) à set to
1msec.

- Click “Ok” to confirm.
1.1.2 Dynamixel Wizard
i. Operating a Dynamixel PRO
- Supply 24V power to Dynamixel PRO once the wiring is complete. For safety,
finish connecting the wires before supplying the power.
- Open RoboPlus to run Dynamixel Wizard.
- Select a COM Port that refers to the correction of USB-to-Dynamixel dongle to
your PC and click button to connect to USB-to-Dynamixel.
- Once the port is connected, select ‘DXL 2.0’ and ‘57600,’ then click ‘Start
Searching.’ Dynamixel PRO’s Default ID setting is 1 and baud rate of 57600 bps.
