Cable to connect XL430 to OpenCM 9.04 C-Type

Technical Support
1

Hi, in order to build a less hardware intense version of my XL430-based azimuth thruster I just try to connect the XL430-W250-T to my C-Type OpenCM 9.04 board.

I have a a small collection of cables, put nothing that fits.

The eManual is quite elaborate on the connector types, but a direct lead to the right cable (incl. ROBOTIS part number) woud be helpfull.

Thanks in advance for your replies…

Kai

Assuming that you also use a 485-EXP board (OpenCM 485 Expansion Board - ROBOTIS) to power the XL430 servo, then you also need this “convertible” cable (Robot Cable-X3P 180mm (Convertible) (10pcs) - ROBOTIS).

#1. If you are using OpenCM 9.04 standalone without extension board, you have to make your own custom cable.

As the X series uses JST connector types, you might need either to make a Molex to JST convertible cable on your own or to buy Robot Cable-XL320 (Convertible) 130mm (recommended). Feel free to see the connector information from e-Manual for your reference.

#2. If you have an extension board (OpenCM485 EXT), highly recommend to get Robot Cable-X3P (Convertible) 180mm provided by ROBOTIS e-Shop (Note that it is using different molex type in size compared to the one above.)

Hope you find this helpful,

Thank you very much for the information regarding the XL320 Convertible Cable. Surprisingly, ROBOTIS-USA does not carry this item, I’ll drop them a note!

Oh… I see,

Thank you for your report. I’ve already contacted people in charge to add the convertible cable between XL-320 and X (TTL).

Thanks again,

Question: Is there a drawback when not using the OpenCM 485? Since there is a considerable amount of soldering involved, I would like to avoid this…

You do not have to go with OpenCM 485 board. It is designed to extend more DYNAMIXEL ports and support 24V voltage units such as DYNAMIXEL-P series or DYNAMIXEL-X with V model.

  • OpenCM9.04 only pass up to 5 - 16 input voltages

For your information, Robot Cable-X3P (Convertible) 180mm would not have you do a soldering task if used.

…would not have you do a soldering task if used.

I was referring to the I/O Header strips one has to solder to the OpenCM 9.04 in order to connect it to the EXP485… :wink:

According to this Robotis e-manual link (OpenCM 9.04), the minimum soldering work can be done with/for the Power connection/cable (which must be custom made), then you can buy/use the XL-320 Convertible Cable (오류안내 페이지 | ROBOTIS) to link your XL430 directly to the OpenCM-904/C bus. They show an example power circuit for the AX12 but it should work for the XL430 in the same way, as both need 11-12 V for power.
