Pinout

Power

The pin composition of CM-700 power is as below.

External 5-Pin Port

Users can create a sensor to control and connect to the 5 pin peripheral device connection port. However, composing the wrong circuits may damage your controller’s circuit, so please learn more about circuit before doing so.
Below is the 5 pin layout information for a peripheral device.

  1. OUT : 5V Output Possible (Maximum Allowed Current 0.9A)
  2. VCC (5V)
  3. ADC : The analog signals from the sensor made by the user can be read.
  4. GND
  5. NC : Not Used

Communication Device Connection Port

The functions of pins on the communication device connection port are as follows.

  1. TXD : Transmit Signal Terminal
  2. RXD : Receive Signal Terminal
  3. VCC : Supply Voltage (2.7 ~ 3.6V)
  4. GND : Ground Level (0v)

3-Pin Connector Port

The functions of pins on the 3-pin connector port are as follows. Please refer to Pin Assignment for more information.
Please be careful not to change the direction considering the angular part.

  1. GND : Ground Level (0v)
  2. VDD : Supply Voltage (It is equal to the voltage of battery)
  3. DATA : Data Transmission Pin

WARNING: Check the pinout! The pinout of Dynamixel can differ from the pinout of connector manufacturer.

4-Pin Connector Port

The functions of pins on the 4-pin connector port are as follows. Pleaser refer to Pin Assignment for more information. (It is compatible with 4-pin of DX and EX Series.) Please be careful not to change the direction considering the angular part.

  1. GND : Ground Level (0v)
  2. VDD : Supply Voltage (It is equal to the voltage of battery)
  3. DATA+ : Data Transmission Pin
  4. DATA- : Data Transmission Pin

WARNING: Check the pinout! The pinout of Dynamixel can differ from the pinout of connector manufacturer.

Sub-Board Connector Information

The pin layout of the connector which connects CM-700 and SUB board is as below.

Connecting Power

The CM-700 which consists of a micro-controller, is divided into a power department, various connectors, and SUB board. Depending on the connection of each board, the working voltage range may change so please refer to the below information to make your own battery.

Dynamixel In Use Min. Voltage Max. Voltage Li-Po Conversion Ni-MH Conversion
AX-12A 9 12 3 cells 8 ~ 10 cells
DX-117 12 18.5 3 ~ 5 cells 10 ~ 15 cells
RX-10 9 12 3 cells 8 ~ 10 cells
RX-28 12 18.5 3 ~ 5 cells 10 ~ 15 cells
RX-64 12 18.5 3 ~ 5 cells 10 ~ 15 cells
EX-106+ 12 18.5 3 ~ 5 cells 10 ~ 15 cells
MX Series 10 14.8 3 ~ 4 cells 9 ~ 12 cells

Connect the battery into the CM-700’s battery socket, and then set the power switch to supply power. Once the power is supplied, the POWER LED will turn on, and one of the MODE LED will start blinking.

How to Operate

Connect to PC

For the PC and CM-700 to communicate, LN-101 must be connected to CM-700 Port.

Wireless Communication

ZIG-110 wireless communication module can be connected to CM-700.

Fuse Replacement

There is a fuse to prevent from damaging the circuit due to over current.
If the CM-700 does not turn on, there is a high chance your fuse is blown. Replace the fuse right away.

※ The fuse size of CM-700 is as below, and you may use a product with a capacity between 125V / 5A ~ 10A. (It is the same as CM-510)
