RS-485 compliant drivers deliver a minimum differential output of 1.5 V over a 60-Ω load, while compliant receivers can detect a minimum differential input of 200 mV.
Q: How does the differential signal method in RS485 improve data communication over RS232? This "current" driven principal is how an 4-20 milliampere analog signal can work over 100’s of feet. In the end, the cable you use needs to work for the application where you use it.

It is NOT ok to contact this poster with commercial interests.
