I recommend you start a new thread and give a lot more information on what you have and where you are stuck.  There are plenty of examples floating around.  But to help, we need to know protocols and any code to show where you are stuck.

Hi,

Thank you very much. I manage to control the shutter finally. Indeed need to convert data using bytes-to-string. However, my shutter still doesn't reply me anything. The read buffer is just empty.

Best,

Lu
