question about PC control AX-12+

i've bought a USB2Dynamixel to control the AX-12+, and i've succeeded to control it ,change its ID number,its speed...

but before i bought your USB2Dynamixel,i tried to use other USB-TO-TTL device to control it,and i use MFC AxtiveX Comm to program.

i found it's useless,AX-12+ can't understand the instruction i send to it!

i wonder why i can't control it without USB2Dynamixel.

is that because USB2Dynamixel is essential to control AX-12+ through PC and other USB-TO-TTL device can't take the place of it.

I use many different controller with the AX-12.  As long as you send a properly formatted signal you can communicate with an AX-12 network.


AX-12 default to 1Mbps and the bus is half duplex.  Most off-the-shelf  USB to RS232 TTL are not half duplex and would require an external circuit.

Thanks for your help, Mike!

 

Yes, the 1Mbps is not the baud rate for the normal serial port. There are many USB 2 serial devices out there which can't open the COM port.

This is probably because they do not support the communication speed. Thus, I recommend using our USB2Dynamixel.
