Recommended Standard Designations
Electronic Industries Association (EIA) designations supersede Recommended Standard (RS)
designations. Reference to the old RS designations (e.g., RS-232) may appear where it might
concern actual text displayed on the unit’s rear panel, Serial Interface, or Web Server Interface
pages. All other references in the manual use the EIA designations.
