I am having trouble connecting the RX-64 Dynamixel servo to the RX 
bridge + Arbotix microcontroller (from here: http://code.google.com/p/arbotix/wiki/home). I am powering everything properly 

and I know that the code I upload to the microcontroller is being 
received because I added a simple blink command to pin 0 of the 
arbotix and I see the LED blink accordingly. The problem is that the 
Dynamixel does not seem to respond to any commands. 

I took the code from here (http://code.google.com/p/arbotix/wiki/ 
GettingSetup) but when I plug everything in, the RX-64 does not move 
(I do see a red light on the back of the RX-64 flash once though). 

It looks like the motor does not send anything back either.

After looking on the signal line, it looks like the baud rate is approx = 58800 which is within 3% of 57600 (which is acceptable according to the rx-64 datasheet). On the scope I also see two long stretches of "HIGH" which I believe corresponds to the 0xFF command that precedes every instruction to the motor.

Thanks in advance for any assistance and I apologize if this isn't the 
correct place to post questions (in which case, I'd appreciate a 
redirection!) 

Ilya.
