Serial Monitor Max485 and Dongle

Using Arduino Networking, Protocols, and Devices
#1

I am working on several Halloween Skeleton. I was able to get Ardunio Nano with several Servos, LEDs, and IR sensors working with one USB. But I could not get run several Ardunio with servos, LEDs, and IR sensors on RS485 in long distance. I have some Max485 and a dongle. I could not find any example codes for RS485 on the serial monitor that can run several Ardunio Nano on RS485. Look at the attached file which I have on my wiring diagram. I need the code for each Arduino and how to run a Serial monitor withMax485.

cannot see attached wiring diagram file?
what USB-RS485 dongle are you using?
what software are you using on the PC to communicate with the dongle?
can you show us your code?
