I am going to develop a pan/tilt unit for CCTV system.
The stepper motors inside the pan/tilt unit will be controlled by Pelco RS485 keyboard (https://www.pelco.com/controllers-keyboards).
I use Arduino UNO Board , ST6600 drivers and stepper motors type JK42HS40-1704 for this project.
The pan/tilt work well by a analogue joystick. Now I go further to Pelco RS485 keyboard.
I hope somebody in this forum can give me the idea how to converter RS485 signal to analogue signal or some other idea for my project. Thank you.
