Frequently Asked Questions

Question 16:  When do I need to turn ON the terminator (120Ω End-of-Line Resistor)?

Answer:  Turn ON the Terminator - End of Line Resistor (120Ω), to prevent interference on the data line.  However, since the Terminator will increase the load on the data circuit, we recommend to turn ON the Terminator only when data rate is over 19,200bps or when the distance exceeds 660 feet (200m).
