1.2 TI Precision Labs - RS-485: How far and fast can RS-485 communicate?

설명

2019년 12월 11일

Questions about RS-485 regarding distance and speed are commonly asked. This video provides an example of how a fast data rate on a long distance transmission line can be affected by the cable's parasitic capacitance, parasitic resistance, and system's jitter. Ultimately, strong drive strength RS-485 drivers are desirable but the quality of the communication medium (cabling) is the limiting factor for far distance transmission.
