RX Series

 

Connection to UART

To control RX Series with a personally made Main Controller, the signal of Main Controller UART should be converted into RS485 type signal. The following is a recommended circuit diagram.

The power of Dynamixel is supplied via Pin1(-), Pin2(+).

(The above circuit is built into Dynamixel-only controller.)

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 DIRECTION 485 as follows:

In case of DIRECTION485 Level = High: The signal of TxD is output to D+ and D-.

In case of DIRECTION485 Level = Low: The signal of D+ and D- is output to RxD.

 

Pin Assignment

The pin assignment of a connector is as shown below. The RX-series Dynamixel has  two 4pin connectors on it and those two connectors have the same function. So, you may use any of the two when connecting the actuators.

Wiring

Wiring should be done Pin2Pin as shown below. By connecting as such, several RX-series can be controlled on a BUS.

Caution : Please pay special attention to avoid incorrect pin assignments in wiring. Otherwise, Dynamixel may be damaged.

 

Confirmation of Connection

The LED of Dynamixel flickers once if the power is supplied to Dynamixel properly via wiring.
