Dyanmixel RX-24F

I am trying to operate RX-24F motors. I am currently using the link below for a schematic and code

But nothing is happening. the LEDs of the MAX board, Arduino Mega 2560 and the motor all turn on. I tried uploading the program by first disconnecting the receive and transmit pins but still nothing. I checked the Servo ID and Baud rate and both match the ones in the program.

The datasheets seem to be the same.

I even tried using the ax-12 library but it does not work.

can anyone help please?
