Dynamixels not found

[boutboutnico]

Hi all,
I have a weird problem. In fact, the all dynamixels are not recognize by the cm-5. I checked the all wire, nothing. I have try to do a recovery with the bioloid_ver115.hex, nothing else. Robot terminal send back to me the following error : error 8100. I have checked the other topic which talk about this but they don't hepl me. Even, in the behavior controller, it is not able to find the motors. I don't know what to do!!
Help is welcome
Nico

When I had this problem it was because I had managed to plug one of the bus connectors into a dynamixel the wrong way round. This effectively shorts the signal lead of the bus to 0v and stops all comunication. Just try connecting one dynamixel into the CM5 and see what you get.

I have tryed to put just one dynamixel into the bus but the cm-5 does not recognize even one dynamixels. I have tryed with different and nothing.
thanks for help

So I have may be the solution. I did not try on all dynamixels but I don't know why I must set the ID for each. Then, the cm-5 is able to find the dynamixel.
That's work.
