Communication Circuitry

Connection to UART

To control DYNAMIXEL-P with a custom made Main Controller, the signal of Main Controller UART should be converted into RS-485 signal. The following is a recommended conversion circuit diagram.

NOTE: Above circuit is designed for 5V or 5V tolerant MCU. Otherwise, use a Level Shifter to match the voltage of MCU.

The power is supplied via Pin1(-) and Pin2(+) of DYNAMIXEL. (The above circuit is built into DYNAMIXEL-only controllers)

In the above circuit diagram, the direction of data signal of TxD and RxD in the TTL Level is determined according to the level of TX_Enable_5V as follows:

Pin Arrangement

Connector pin arrangement is shown below. DYNAMIXEL-P has two 4-pin connectors arranged in pin-2-pin configuration. In this arrangement there’s no priority in the connector order and DYNAMIXEL-P can be driven like the MX-series.
Additionally there is a 2-pin connector dedicated for power input for high-current operations.

WARNING : When wiring please pay attention to the pin arrangement. Incorrectly connected DYNAMIXEL-P may be damaged severely.

Confirmation of Connection

The LED of DYNAMIXEL-P flickers once if the power is supplied to DYNAMIXEL-P properly via wiring.


The output horn has been redesigned. Please refer to below comparisons between DYNAMIXEL PRO and DYNAMIXEL-P.
