U2D2
can be connected to the USB port of the PC with the enclosed USB cable. It supports both 3Pin TTL connector and 4Pin RS-485 connector to
link up with various DYNAMIXELs.
DYNAMIXEL.
Be careful as recommended voltage for each DYNAMIXEL could be vary by model.
Please refer to e-Manual for recommended supply voltage and power connection with various power supplies.
PC to UART
U2D2 is able to connect ROBOTIS controllers that support 4Pin UART communication such as OpenCM9.04, CM-150 and CM-200 to the PC with
the enclosed USB cable.
In case of unstable communication with U2D2, check if there is a reference voltage difference in the communication.
Please check PC and other devices are grounded properly.
Failing to do so might cause damages on the U2D2.
