RS-485. Use of the two terms—RS-422 and RS-485—can be confusing in engineering drawings. When drawings include Liebert SiteLink-E wiring details, Liebert suggests labeling any occurrences of RS-422 as “RS-422 (RS-485 four-wire).” Vertiv | Liebert® SiteLink-E™ Installation Manual |... - Page 24 During the transmission of a logic 0 (less than -200mV), the network will be in the space state (ON, logic 0). Liebert’s DIAG boards can serve as bias on RS-485/RS-422 networks. Apply bias in the middle of the network, and apply termination only at the two end devices.
