Thread: Dynamixel MX64T 3pin TTL and 4pin RS485 version

  1. Dynamixel MX64T 3pin TTL and 4pin RS485 version

    Hi all,

    I am currently working on a three joint robotic arm with MX64T,MX28T and AX12A used for joint 1, 2 and 3 respectively. I am using the Arbotix-M Robocontroller to control them.


    I wanted to replace the MX-28T with a MX-64T as I needed more torque and therefore I ordered a new one. But the problem is I have received a 4pin MX-64T which I think is the RS485 communication version and not the TTL version. All my other servos in my system uses the 3pin TTL. So is there any way of using this 4pin MX-64T in my system or do I need to get a replacement?

    Any help will be greatly appreciated. Thanks.

    a 4pin MX-64T
    There is no such thing -- that's a MX-64R.
    Your absolutely best bet is to return it in exchange for a MX_64T.
    If your order was actually for an MX-64T, I'd expect the dealer would recognize the mistake is on their part.

    Sorry that was a typo on my end.

    But yes I have spoken to the dealer and they are sorting it out now.

    Thanks for your help.
