Hi lkp857, this is my opinion..
lkp857 WROTE:Can we send a command to turn on/off the servo? or some other thing that it can do?
To turn ON/OFF servo you need to connect/disconnect the servo supply. You can add mosfet/relay or any switching component at the servo supply and it should be able to handle in high current (because servo operate in high current). For 'some other thing that it can do' maybe you can refer to Cytron IFC Servo Card functions.
