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.

Metric Conversion

Metric conversion information is provided on the inside back cover of this manual. Comtech EF
Data provides this information to assist the user in cross-referencing non-Metric to Metric
conversions.
