Frequently Asked Questions

Question 17:  Which type of cable is recommended for RS-485 / RS-422 connections?

Answer:  Inexpensive Cat 5 shielded cables (STP - shielded twisted pair) generally exceed the recommendations for RS-422 (although its characteristic impedance is 100Ω rather than the required 120Ω). This makes it an excellent choice for RS-485 and RS-422 systems.
