A device with an RS-485 or RS-422 port might include a built-in termination resistance you can connect to a bus if needed or leave disconnected. Use only two terminating resistors! Typically, twisted pair wire has an impedance of about 120 ohms, so we use 120-ohm resistors at the ends on the longest cable runs. WebInstead of using pull-up or pull-down resistors, the parallel 120-Ohm end-of-line terminators provide a hassle-free and effective way of termination. However, since the Terminator will increase the load on the data circuit, we recommend to turn ON the Terminator only when the data rate is over 19.2kbps or the distance exceeds 660 feet (200m).
